WalkthroughJDBC incremental readers can use a configured or detected server timezone. SQL generators accept the timezone when building datetime offset conditions, and dialect implementations provide timezone queries or parsing. The change also adds timezone parsing utilities and related tests. ChangesJDBC timezone-aware incremental queries

Datetime bounds now know their way.

Add defaults for the new timezone members, but document the signature change as breaking.
The default Failure for SqlGenerator.getServerTimezone does not preserve direct custom implementations that still use the old getDataQueryIncremental signature. It only removes the new abstract-method requirement.
SqlGeneratorBase provides the new incremental method itself, so subclasses that inherit it are not affected by that signature change. However, the new abstract getServerTimezoneQuery breaks existing subclasses that do not implement it. Give that member an unsupported default. Do not imply that this fixes the changed incremental-query signature for direct implementations or subclasses that override it.
Document the getDataQueryIncremental signature change in the release notes.

Include connection acquisition in the timezone fallback.
When no timezone is configured, jdbcUrlSelector.getConnection runs outside the Success/Failure handling. If connection acquisition fails after retries, defaultTimeZone is not used.

When MySQL returns an unparseable @@system_time_zone value, ZoneId.of fails and TableReaderJdbcBase falls back to defaultTimeZone. For a datetime offset, this timezone reaches getGenericTimestampString and can produce incorrect incremental predicates.
A current numeric offset is not safe because it does not preserve DST rules. Use an explicit regional server.timezone value for MySQL SYSTEM deployments, or fail detection when no such value is configured instead of silently using the generic default. This is a narrow conditional ingestion error, not evidence of irreversible data loss.

Update getServerTimezoneQuery and its timezone-detection flow so MySQL SYSTEM
deployments use an explicitly configured regional server.timezone or fail
detection when none is configured; do not substitute a fixed current offset or
allow an unparseable system zone to silently fall back to the generic default.
After applying the fix, consider running `coderabbit review --agent` for local

Use server.timezone for DST-observing DB2 deployments.
SqlGeneratorDb2.getServerTimezone converts CURRENT TIMEZONE into a fixed ZoneOffset. The JDBC readers pass that value to getGenericTimestampString, which formats each Instant as a local DB2 timestamp. If a datetime bound comes from another DST season, the generated predicate can use the wrong timestamp and omit or duplicate incremental rows.
Configure server.timezone with a regional ZoneId for DST-observing DB2 deployments. Keep automatic CURRENT TIMEZONE detection for deployments that use a fixed offset. TableReaderJdbcBase already gives the explicit setting precedence, so this correction is DB2-specific and does not require changing SQL Server.

Update the DB2 timezone resolution path around SqlGeneratorDb2.getServerTimezone

Preserve a region-based timezone for SQL Server DST deployments.
When server.timezone is not configured, SqlGeneratorMicrosoft converts DATEPART(TZOFFSET, SYSDATETIMEOFFSET()) into a fixed ZoneOffset. A datetime bound from the opposite DST season is then converted with the discovery-time offset, so the generated incremental predicate can use a local boundary that is one seasonal offset away. This can skip rows or include rows outside the requested range.
Use CURRENT_TIMEZONE_ID() on SQL Server versions that support it, map its Windows timezone name to a Java ZoneId, and retain explicit server.timezone or a fixed-offset fallback for older or fixed-offset deployments. Do not derive a region from the current offset alone.

Update getServerTimezoneQuery and getServerTimezone so supported SQL Server
versions use CURRENT_TIMEZONE_ID() and map the returned Windows timezone name to
a Java ZoneId, preserving a region-based timezone for DST changes. Keep an
explicitly configured server.timezone authoritative, and retain the current
fixed-offset discovery as a fallback for older SQL Server versions or
fixed-offset deployments; do not infer a region from the current offset alone.

Specify the options as you specify the database-definition arguments when using the PROC SQL statement CONNECT TO. ... A Boolean value that determines whether the SAS/SHARE driver for JDBC returns the data set label for each data set in the library that your program accesses.
(libname 'filepath'; libname 'filepath';...)
`dbms`
The name of the DBMS your program will access; the value must be eight characters padded with blanks. The default is "SQLVIEW ", which specifies that SAS data sets will be accessed. If you are not accessing SAS data, specify the name of the foreign DBMS as it is defined using SAS/ACCESS software.
`dbms_options`
Options for the foreign DBMS your program will access. Specify the options as you specify the database-definition arguments when using the PROC SQL statement CONNECT TO.
`remarks`
A Boolean value that determines whether the SAS/SHARE driver for JDBC returns the data set label for each data set in the library that your program accesses. If the value is True, the labels are returned; the default value is False.
Note: When this property is set to True, any operation that involves reading and returning data set labels can result in poor performance because each data set must be opened in order to read the label. For example, if this property is set to True, performance may be degraded when using the ShareNetDatabaseMetaData.getTables() method to retrieve a description of the tables in a catalog.
`undoPolicyNone`
A Boolean value that determines whether changes to the data are undone when an UPDATE or INSERT statement generates errors. When the value is set to True (the recommended setting), the changes are not undone; when the value is set to False, the server attempts to undo the changes.
`routerUrl`
The URL of the Message Router. The `routerUrl` property value must be specifies as follows:
(routerUrl http://your_server/cgi-bin/shrcgi)
where `http://your_server/cgi-bin/shrcgi` is the URL of the Message Router (`shrcgi` or `shrcgi.exe`), one of the tunnel feature's server programs.
## Feature Support Details
This section discusses the support that the SAS/SHARE driver for JDBC provides for various common DBMS features. It also lists the SQL data types and table types that are supported.
### Stored Procedures
SAS software does not support stored procedures. While we provide the class ShareNetCallableStatement, none of its methods are supported.
### Foreign DBMS Metadata
When the ShareNetConnection class establishes a connection with a SAS/SHARE server, it creates a ShareNetDatabaseMetaData object for SAS data sets only. If your program connects to a foreign DBMS, no metadata will be returned.
### SQL Catalogs
SAS software does not support SQL catalogs. Parameter input that specifies SQL catalog information to SAS/SHARE driver for JDBC methods is ignored.
### Supported SQL Data Types
The following list identifies the SQL data types that are supported by the SAS/SHARE driver for JDBC:
* CHAR
* VARCHAR
* INTEGER
* FLOAT
* DOUBLE
* DATE
* TIME
* TIMESTAMP
### Supported Table Types

# SAS/SHARE^{®} Driver for JDBC Specifics
The SAS/SHARE driver for JDBC complies with version 2.0 of the Java Database Connectivity (JDBC) API specification from Sun Microsystems. However, some features such as record-level locking and scrolling are not supported with SAS software. The remainder of this page discusses other details about our implementation of the JDBC specification.
## Connecting to a Database
The getConnection methods in the JDBC DriverManager establish a connection to a database. Connection arguments can be specified in either a URL or a java.util.Properties object.
Note: If you specify the connection arguments in both the java.util.Properties object and the URL, the values in the URL will take precedence.
The URL must be of the form:
jdbc:sharenet://hostname:portnumber<?`property-1`=`value-1`<...&`property-n`=`value-n`>>
where
`hostname`
specifies the name of the machine where the SAS/SHARE server is running
`portnumber`
specifies the port the SAS/SHARE server is configured to use
`undoPolicyNone`
A Boolean value that determines whether changes to the data are undone when an UPDATE or INSERT statement generates errors. When the value is set to True (the recommended setting), the changes are not undone; when the value is set to False, the server attempts to undo the changes.

JDBC Best Practices
Use JDBC Batch Update for Large Inserts
It is a best practice to insert and update large amounts of data in batches. When
performing a large number of parameterized inserts, use JDBC Batch Update. When you
submit multiple SQL statements in batch instead of individually, the number of round
trips to the database is reduced, which results in significant performance improvement.
Here is an example:
PreparedStatement pstmt = null;
pstmt = connection.prepareStatement("INSERT INTO \"USERS\"VALUES (?, ?, ?)");
pstmt.setString(1, "john_doe");
pstmt.setInt(2, 25);
pstmt.setString(3, "like to walk");
pstmt.addBatch();
pstmt.setString(1, "john_moe");
pstmt.setInt(2, 50);
pstmt.setString(3, "like to play");
pstmt.addBatch();
pstmt.setString(1, "john_coe");
pstmt.setInt(2, 60);
pstmt.setString(3, "like to eat");
pstmt.addBatch();
pstmt.executeBatch();
SAS Federation Server conforms to the following Oracle JDBC rule:
For any given statement, an application should not modify the value argument passed to
a setXXX method after the setXXX method is called and before the subsequent
execute, executeQuery, executeUpdate, excuteBatch, or
clearParameters method is called. An application can modify the value argument
after the execute, executeQuery, executeUpdate, excuteBatch, or
clearParameters method is called, if there is a subsequent setXXX method call that
overwrites the previous value or if the statement is not reused. Failure to conform to this
restriction can result in unpredictable behavior.
Statement Pooling
Use the statement pooling feature when executing the same statement multiple times.
Statement pooling improves performance by reducing processing for the allocate and
prepare statements.
Invoking last and isLast Methods
Some databases and underlying drivers do not support a scrollable result set. In this case
when requesting this type of a result set the following error message within an exception
is returned: Unable to create Statement with requested result set
concurrency[1008]. Here is an example of this request:

### OUTPUT Statement
* OUTPUT OUT=SAS-data-set keyword=names <…keyword=names> </ options>;
The OUTPUT statement specifies an output data set to contain statistics calculated for each observation. For each statistic, specify the keyword, an equal sign, and a variable name for the statistic in the output data set. All of the names appearing in the OUTPUT statement must be valid SAS names, and none of the new variable names can match a variable already existing in the data set to which PROC NLIN is applied.
If an observation includes a missing value for one of the independent variables, both the predicted value and the residual value are missing for that observation. If the iterations fail to converge, all the values of all the variables named in the OUTPUT statement are missing values.
Table 6 summarizes the options available in the OUTPUT statement.

Chapter 5 / OPTIONS Procedure
SAS system options control how SAS formats output, handles files, processes data sets, interacts with the operating environment, and does other tasks that are not specific to a single SAS program or data set. You use the OPTIONS procedure to obtain information about an option or a group of options. Here is some of the information that the OPTIONS procedure provides:
- the current value of an option and how it was set
- a description of an option
- valid syntax for the option, valid option values, and the range of values
- where you can set the system option
- if the option can be restricted by your site administrator
- if the option has been restricted
- system options that belong to a system option group
- system options that are specific for an operating environment
- if an option value has been modified by the INSERT or APPEND system options
- system options that can be saved by the OPTSAVE procedure.
For additional information about SAS system options, see *SAS System Options: Reference*.

Identify Where an Option Was Set
You can specify the VALUE option in a PROC OPTIONS statement to identify the option’s scope and the method that was used to set the option. If an option’s value is set using multiple methods (for example, in an OPTIONS statement or in multiple configuration files), the VALUE option identifies which method determines the effective value. If the method is a configuration file, the VALUE option identifies the file path.
Use the following PROC OPTIONS statement to specify the VALUE option:
proc options option=option-name value;

if the next statement is SET, MERGE, or UPDATE. Different, but significant,
problems arise when the next statement is RETAIN. DATASTMTCHK= enables you
to protect yourself against overwriting the input data set.
DATE System Option

L1: # How the SAS/SHARE^{®} Driver for JDBC Works
L2:
L3: With the SAS/SHARE driver for JDBC, you can interactively view and update SAS data or any other data that is accessible through a SAS/SHARE server. The following diagram shows how an applet created using the SAS/SHARE driver for JDBC communicates with a SAS/SHARE server:
L4:
L5: 【0†Image: [SAS/SHARE driver for JDBC diagram]】
L6: The Web browser on the client machine requests an HTML document from the Web server. The server responds by sending the document to the browser. If the browser detects an applet tag in the document, it sends additional requests to the Web server for the Java classes used by the applet. After the classes are downloaded to the client machine, the applet begins running.
L7: The applet uses the JDBC driver classes to establish a connection to the SAS/SHARE server. After the connection is established, the driver provides SQL (Structured Query Language) access to the SAS/SHARE server. The applet can send SQL statements to the server and retrieve the results generated by those statements.
L8: The SAS/SHARE driver for JDBC supports the SQL statement SELECT to obtain data as well as the SQL statements CREATE, UPDATE, INSERT, and DELETE to modify data. The results for an SQL SELECT statement are the set of rows and columns specified by that statement. The result of an SQL UPDATE statement is the number of rows modified by that statement.
L9: The JDBC driver classes accept a URL that identifies the SAS/SHARE server. The URL is of the form ` jdbc:sharenet://hostname:portnumber`. Hostname is the name of the machine where the SAS/SHARE server is running and portnumber is the port the SAS/SHARE server is configured to use.
L10: By default, the JDBC classes use socket-based communication with the SAS/SHARE server. Socket communication with applets can be restricted by the Java security manager. The security manager is provided by the browser, and each browser has a different set of restrictions imposed on applets. Most security managers restrict socket-based communication and only allow applets to open socket connections to the same machine that provided the applet classes.
L11: This means the SAS/SHARE server and the Web server that provides the Java classes must run on the same machine. The 【1†tunnel feature】 eliminates this restriction, enabling you to install your Web server and your SAS/SHARE server on different machines.
L12: For more information about the JDBC API specification as provided by Sun Microsystems, visit the 【2†JDBC page†java.sun.com】.

TIMEZONE= System Option 393
hh specifies an hour by using one or two digits. If you specify an offset, the hour is required.
mm specifies minutes by using one or two digits. Minutes are optional.
ss specifies seconds by using one or two digits. Seconds are optional.
time-zone-ID
specifies a region/area value that is defined by SAS. When you specify a time zone ID, the time zone that SAS uses is determined by time zone name and Daylight Saving Time rules.
Note Time zone IDs are compatible with Java time zone names.
See For a list of time zone IDs, see Appendix 1, “Time Zone Information and Time Zone Names,” on page 471.
Details
You set the TIMEZONE= option to a time zone ID or a time zone name in order for SAS to use a particular time zone. The time zone setting affects the following SAS components:
- times that are recorded by events and logs
- time of data set creation or modification
- DATE() function
- DATETIME() function
- TIME() function
- TODAY() function
- time zone functions TZONEOFF(), TZONEID(), TZONENAME(), TZONES2U(), and TZONEU2S(),
- time zone formats B8601DXw., E8601DXw., B8601LXw., E8601LXw., B8601TXw., E8601TXw., NLDATMZw., NLDATMTZw., and NLDATMWZw.
You set a time zone by specifying a time zone ID or a time zone name. A time zone ID is a region and an area separated by a forward slash ( / ). For example, America/New_York and Asia/Osaka are time zone IDs.
A time zone name is a three- or four-character name for a time zone. For example, EST is Eastern Time and JST is Japan Time. SAS determines the time by using time zone rules, including daylight saving time rules, before using a time value.
Some time zones names are valid for different locales. For example, CST is Central Standard Time, Cuba Daylight Time, and China Standard Time. SAS uses the value of the LOCALE= system option to determine the region and area to use. If TIMEZONE='CST' and LOCALE='zh_CN', SAS uses the Asia/Beijing time zone. If the time zone name does not exist for the locale, SAS searches all time zones and sets the time zone to the first match that it finds.</excerpt>

- The CONNECT statement is required.
- PROC SQL supports multiple connections to JDBC. If you use multiple simultaneous connections, you must use the alias argument to identify the different connections. If you do not specify an alias, the default JDBC alias is used. The functionality of multiple connections to the same JDBC data source might be limited by the particular data source driver.

<title>Accessing Your Favorite Database with SAS® and JDBC</title>

a JDBC driver using the service provider mechanisms that were introduced with JDBC
4.
URL
This option specifies the JDBC connection string to use to connect to your data
source. It is used as is and is not modified or parsed by SAS/ACCESS Interface to
JDBC. The Teradata JDBC connection string used in this paper is as basic as you can
get. It is jdbc:teradata://teradata.sas.com.
In addition to those three options, you must set these options for the JDBC driver.
USER (alias: UID)
This option specifies the user name to use to connect to your data source through a
call to DriverManager.getConnection(String url, Properties info). If the user name
contains spaces or non-alphanumeric characters, you must enclose it in quotation
marks. The user name must be set with this option and cannot be set using the
URL= option.
PASSWORD (alias: PWD)
This option specifies the user password to use to connect to your data source. If the
password contains spaces or non-alphanumeric characters, you must enclose it in
quotation marks. If you do not want to enter your password in plane text, see PROC
PWENCODE in the Base SAS® 9.4 Procedures Guide for a method to encode it. The
user password must be set with this option and cannot be set using the URL= option.
SCHEMA
This option specifies the schema that you want to use when loading and accessing
tables in your data store. If the schema name contains spaces or non-alphanumeric
characters, you must enclose it in quotation marks. The SCHEMA= option is required
if your JDBC driver is older than 4.1 or if your database vendor did not implement
the Connection.getSchema method. If SAS/ACCESS Interface to JDBC cannot
discover your SCHEMA by calling Connection.getSchema or if the SCHEMA= option is
omitted, this error message is displayed in your SAS log.
ERROR: java.lang.AbstractMethodError
ERROR: Error retrieving DatabaseMetaData: java.lang.AbstractMethodError
PRESERVE_NAMES
Many modern data source today allow for the use of mixed-case table and column
names. This option preserves spaces, special characters, and case sensitivity of the
table and column names in your data source. Use this option when connecting to
data source that allow for mixed case table and column names.
LIBNAME STATEMENT
The SAS/ACCESS Interface to JDBC LIBNAME statement extends the SAS global LIBNAME
statement so that you can assign a libref to your data source. This feature lets you reference
a table in your data store directly in a DATA Step or SAS procedure. You can use it to read
from and write to your data source as if it were a SAS data set. This example shows the
basic LIBNAME statement to connect to Teradata.

* * *
public class MVADriver
extends java.lang.Object
implements java.sql.Driver
MVADriver class implements the Driver interface.
The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL.
When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register a driver by doing Class.forName("foo.bah.Driver").

### executeQuery
public ResultSet executeQuery(String query)
throws SQLException
Execute a SQL statement that returns a single ResultSet.
Specified by:
`executeQuery` in interface `Statement`
Parameters:
`query` - Typically this is a static SQL SELECT statement.
Returns:

Executes an SQL INSERT, UPDATE or DELETE statement.
Specified by:
`executeUpdate` in interface `Statement`
Parameters:
`sql` - A SQL INSERT, UPDATE or DELETE statement.
Returns:
The row count for INSERT, UPDATE or DELETE.
### execute
public boolean execute(String sql)
throws SQLException
Execute a SQL statement that may return multiple results. Under some (uncommon) situations a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this, unless you're executing a stored procedure that you know may return multiple results, or unless you're dynamically executing an unknown SQL string. The "execute", "getMoreResults", "getResultSet" and "getUpdateCount" methods let you navigate through multiple results. The "execute" method executes a SQL statement and indicates the form of the first result. You can then use getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).
Specified by:
`execute` in interface `Statement`
Parameters:
`sql` - An SQL statement
Returns:
True if the next result is a ResultSet. False if it is an update count or there are no more results

Do not send PROC OPTIONS through executeQuery.
The SAS IOM JDBC driver treats executeQuery as an SQL operation that returns an MVAResultSet. SAS documents PROC OPTIONS as writing the option listing to the SAS log, not as returning a result set. Therefore, timezone detection can fail and TableReaderJdbcBase uses defaultTimeZone. When that default differs from the SAS timezone, incremental datetime filters can use the wrong timestamp boundary. Replace this with a supported result-producing timezone query or require an explicit serverTimeZone.

around lines 88 - 89:
Replace the PROC OPTIONS statement returned by getServerTimezoneQuery with a
supported query that returns the SAS server timezone through executeQuery, or
require an explicit serverTimeZone if no result-producing query is available.
Ensure timezone detection does not fall back to defaultTimeZone because the
query produces no result set.

<excerpt>citeturn0search12 [wordlim: 200] Published: 2.0 years ago; Crawled: 6 months ago; The methods of the JDBC `ResultSet` interface are used to return values and to convert value to different types as supported by the JDBC specification. ... With this method, you specify the required return type.The common types such as String, Integer, byte[] are supported, as well as new types that can be used for DATE, TIME, TIMESTAMP, and INTERVAL values.
# JDBC Returned Values
The methods of the JDBC `ResultSet` interface are used to return values and to convert value to different types as supported by the JDBC specification. Methods of JDBC `CallableStatement` that have the same signature are used to return values from procedure calls.
When a CLOB and BLOB object is returned from a ResultSet, no data is transferred until the data is read by various methods of `java.sql.CLOB` and `java.sql.BLOB`. Data is streamed in large blocks to avoid excessive memory use.
Array objects are returned as instances of `java.sql.Array`.
Methods added in Java 8 are supported and the behaviour of the `getObject(int columnIndex)` method for retrieving TIMESTAMP WITH TIME ZONE has changed. In versions before 2.4.0, this method returned a `java.sql.Timestamp` object. It now returns a `java.time.OffsetDateTime` object which contains the time zone offset value as well as the other fields of the TIMESTAMP.
A new method, `getObject(int columnIndex, Class<T> type)` is available. With this method, you specify the required return type. The common types such as String, Integer, byte[] are supported, as well as new types that can be used for DATE, TIME, TIMESTAMP, and INTERVAL values. The table below shows which Java classes are the most appropriate for the specified SQL TYPES. In addition, you can use these Java types for values of SQL type that are not fully matched. For example, `java.time.LocalDateTime` can be used to retrieve a DATE value.
<table id="e1">
<tr><td>java.util.UUID = UUID</td></tr>
<tr><td>java.time.LocalDate = DATE</td></tr>
<tr><td>java.sql.Date = DATE</td></tr>
<tr><td>java.time.LocalTime = TIME</td></tr>
<tr><td>java.sql.Time = TIME</td></tr>
<tr><td>java.time.LocalDateTime = TIMESTAMP</td></tr>
<tr><td>java.sql.Timestamp = TIMESTAMP</td></tr>
<tr><td>java.time.OffsetTime = TIME WITH TIME ZONE</td></tr>
<tr><td>java.time.OffsetDateTime = TIMESTAMP WITH TIME ZONE</td></tr>

<excerpt>citeturn0search2 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; Conversion between TIME and TIMESTAMP is performed by removing the DATE field values of a TIMESTAMP value or by appending the fields of the TIME value to the fields of the current session date value. ... When a value is assigned to a datetime target, e.g., a value is used to update a row of a table, the type of the value must be the same as the target, but the WITH TIME ZONE or WITHOUT TIME ZONE characteristics can be different. ... When an SQL session is started (with a JDBC connection) the local time zone of the client JVM (including any seasonal time adjustments such as daylight-saving time) is used as the session time zone displacement.
If the types are not the same, an explicit CAST must be used to convert the value into the target type.
Comparison
When values WITH TIME ZONE are compared, they are converted to UTC values before comparison. If a value WITH TIME ZONE is compared to another WITHOUT TIME ZONE, then the WITH TIME ZONE value is converted to AT LOCAL, then converted to WITHOUT TIME ZONE before comparison.
It is not recommended to design applications that rely on comparisons and conversions between TIME values WITH TIME ZONE. The conversions may involve normalisation of the time value, resulting in unexpected results. For example, the expression: BETWEEN(TIME '12:00:00-8:00', TIME '22:00:00-8:00') is converted to BETWEEN(TIME '20:00:00+0:00', TIME '06:00:00+0:00') when it is evaluated in the UTC zone, which is always FALSE.
Functions
Several functions return the current session timestamp in different datetime types:
CURRENT_DATE | DATE
CURRENT_TIME | TIME WITH TIME ZONE
CURRENT_TIMESTAMP | TIMESTAMP WITH TIME ZONE
LOCALTIME | TIME WITHOUT TIME ZONE
LOCALTIMESTAMP | TIMESTAMP WITHOUT TIME ZONE
HyperSQL supports a very extensive range of functions for conversion, extraction and manipulation of DATE and TIMESTAMP values. See the Built In Functions chapter.
Session Time Zone Displacement
When an SQL session is started (with a JDBC connection) the local time zone of the client JVM (including any seasonal time adjustments such as daylight-saving time) is used as the session time zone displacement. In version 2.7.0 a Java Calendar object with the local time zone of the client JVM is created and used. Therefore when a seasonal time adjustment for daylight saving time is made while the session is open, the SQL session zone displacement is changed. In some older versions of HyperSQL, the SQL session time displacement was not changed when a seasonal time adjustment took place.
To change the SQL session time zone displacement, use the following commands:

<excerpt>citeturn0search3 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; The return type of different versions of a function can be the same or different. ... RETURN CURRENT_TIMESTAMP;
### Return Statement
The RETURN statement is required and used only in functions. The body of a function is either a RETURN statement, or a compound statement that contains a RETURN statement.
The return value of a FUNCTION can be assigned to a variable, or used inside an SQL statement.
An SQL/PSM function or an SQL/JRT function can return a single result when the function is defined as RETURNS TABLE ( .. )
To return a table from a SELECT statement, you should use a return statement such as `RETURN TABLE( SELECT ...)` in an SQL/PSM function. For an SQL/JRT function, the Java method should return a JDBC `ResultSet` instance.
To call a function from JDBC, use a `java.sql.CallableStatement` instance. The `getResultSet()` call can be used to access the `ResultSet` returned from a function that returns a result set. If the function returns a scalar value, the returned result has a single column and a single row which contains the scalar returned value.
RETURN
return statement
`<return statement> ::= RETURN <return value>`
`<return value> ::= <value expression> | NULL`
Return a value from an SQL function. If the function is defined as RETURNS TABLE, then the value is a TABLE expression such as RETURN TABLE(SELECT ...) otherwise, the value expression can be any scalar expression. In the examples below, the same function is written with or without a BEGIN END block. In both versions, the RETURN value is a scalar expression.
CREATE FUNCTION an_hour_before_max (e_type INT)
RETURNS TIMESTAMP
RETURN (SELECT MAX(event_time) FROM atable WHERE event_type = e_type) - 1 HOUR
CREATE FUNCTION an_hour_before_max (e_type INT)
RETURNS TIMESTAMP
BEGIN ATOMIC
DECLARE max_event TIMESTAMP;
SET max_event = SELECT MAX(event_time) FROM atable WHERE event_type = e_type;
RETURN max_event - 1 HOUR;
END
In the example below, a table is defined as the return value. The select statement provides the data to be returned.
CREATE FUNCTION recent_customers(IN since_date DATE)

## Date Time and Interval Functions
Functions to report the time zone.
### Functions to Report the Time Zone.
TIMEZONE
`TIMEZONE()`
Returns the current time zone displacement for the session. This value is the same as SESSION_TIMEZONE if the user has not changed the TIME ZONE of the session. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
SESSION_TIMEZONE
`SESSION_TIMEZONE()`
Returns the initial (default) time zone displacement for the current session. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
SESSIONTIMEZONE
`SESSIONTIMEZONE()`
Returns the same value as SESSION_TIMEZONE. (HyperSQL)
DATABASE_TIMEZONE
`DATABASE_TIMEZONE()`
Returns the time zone displacement for the database engine. This is based on where the database server process is located. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
DBTIMEZONE
`DBTIMEZONE()`
Similar to DATABASE_TIMEZONE. Returns a string. Works in ORA compatibility mode only.(HyperSQL)
### Functions to Report the Current Datetime
CURRENT_DATE
`CURRENT_DATE`
CURRENT_TIME
`CURRENT_TIME [ ( <time precision> ) ]`
LOCALTIME
`LOCALTIME [ ( <time precision> ) ]`
CURRENT_TIMESTAMP
`CURRENT_TIMESTAMP [ ( <timestamp precision> ) ]`
LOCALTIMESTAMP
`LOCALTIMESTAMP [ ( <timestamp precision> ) ]`
These datetime functions return the datetime value representing the moment the function is called. `CURRENT_DATE` returns a value of DATE type. `CURRENT_TIME` returns a value of TIME WITH TIME ZONE type with the time zone of the SQL session. `LOCALTIME` returns a value of TIME type. `CURRENT_TIMESTAMP` returns a value of TIMESTAMP WITH TIME ZONE type with the time zone of the SQL session. `LOCALTIMESTAMP` returns a value of TIMESTAMP type. If the optional `[ ( <time precision> ) ]` or` [ ( <timestamp precision> ) ]` is used, then the returned value has the specified fraction of the second precision. When the functions are used multiple times in a single SQL statement, the returned values represent the same point of time.
From version 2.7.0 the functions return values with microsecond precision. </excerpt>

<excerpt>citeturn0search5 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; Several functions return the current session timestamp in different datetime types: ... When an SQL session is started (with a JDBC connection) the local time zone of the client JVM (including any seasonal time adjustments such as daylight-saving time) is used as the session time zone displacement. ... The literal representation of interval values consists of the type definition, with a string representing the interval value inserted after the word INTERVAL.
## Interval Types
Interval types are used to represent differences between date time values. The difference between two date time values can be measured in seconds or in months. For measurements in months, the units YEAR and MONTH are available, while for measurements in seconds, the units DAY, HOUR, MINUTE, SECOND are available. The units can be used individually, or as a range. An interval type can specify the precision of the most significant field and the second fraction digits of the SECOND field (if it has a SECOND field). The default precision is 2, following the Standard. The default second precision is 0. The default precision is too small for many applications and should be overridden.
`<interval type> ::= INTERVAL <interval qualifier>`
`<interval qualifier> ::= <start field> TO <end field> | <single datetime field>`
`<start field> ::= <non-second primary datetime field> [ <left paren> <interval leading field precision> <right paren> ]`
`<end field> ::= <non-second primary datetime field> | SECOND [ <left paren> <interval fractional seconds precision> <right paren> ]`

<excerpt>citeturn1search3 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; When an SQL session is started (with a JDBC connection) the local time zone of the client JVM (including any seasonal time adjustments such as daylight-saving time) is used as the session time zone displacement. ... The standard function `ABS(<interval value expression>)` can be used to convert a negative interval value to a positive one.The literal representation of interval values consists of the type definition, with a string representing the interval value inserted after the word INTERVAL. ... `EXTRACT ({YEAR | MONTH | DAY | HOUR | MINUTE | SECOND | TIMEZONE_HOUR | TIMEZONE_MINUTE | DAY_OF_WEEK | WEEK_OF_YEAR } FROM {<datetime value> | <interval value>})` ... You can use the URL property hsqldb.translate_dti_types=false to override the default behaviour.
The individual fields of both datetime and interval values can be extracted using the EXTRACT function. The same function can also be used to extract the time zone displacement fields of a datetime value.
`EXTRACT ({YEAR | MONTH | DAY | HOUR | MINUTE | SECOND | TIMEZONE_HOUR | TIMEZONE_MINUTE | DAY_OF_WEEK | WEEK_OF_YEAR } FROM {<datetime value> | <interval value>})`
The dichotomy between interval types based on seconds, and those based on months, stems from the fact that the different calendar months have different numbers of days. For example, the expression, “nine months and nine days since an event” is not exact when the date of the event is unknown. It can represent a period of around 284 days give or take one. SQL interval values are independent of any start or end dates or times. However, when they are added to or subtracted from certain date or timestamp values, the result may be invalid and cause an exception (e.g. adding one month to January 30 results in February 30, which is invalid).
JDBC has an unfortunate limitation and does not include type codes for SQL INTERVAL types. Therefore, for compatibility with database tools that are limited to the JDBC type codes, HyperSQL reports these types by default as VARCHAR. You can use the URL property hsqldb.translate_dti_types=false to override the default behaviour.
Java 8 Extensions
JAVA 8 does not have SQL type codes for INTERVAL types. HyperSQL supports `java.time` types for INTERVAL types in `ResultSet`, `PreparedStatement` and `CallableStatement`.
* The `getObject(int columnIndex, Class type)` method on an INTERVAL supports the `java.time.Period` type for YEAR and MONTH interval and the `java.time.Duration` type for other interval types that cover DAY to SECOND.
* The `setObject(int columnIndex)` method accepts `java.time.Period` and `java.time.Duration` objects for columns of relevant INTERVAL types.
* The `getObject` and `setObject` methods with column name parameters behave just like their counterparts with columnIndexe parameters.

<excerpt>citeturn0search12 [wordlim: 200] Published: 2.0 years ago; Crawled: 6 months ago; The methods of the JDBC `ResultSet` interface are used to return values and to convert value to different types as supported by the JDBC specification. ... The common types such as String, Integer, byte[] are supported, as well as new types that can be used for DATE, TIME, TIMESTAMP, and INTERVAL values.
# JDBC Returned Values
The methods of the JDBC `ResultSet` interface are used to return values and to convert value to different types as supported by the JDBC specification. Methods of JDBC `CallableStatement` that have the same signature are used to return values from procedure calls.
When a CLOB and BLOB object is returned from a ResultSet, no data is transferred until the data is read by various methods of `java.sql.CLOB` and `java.sql.BLOB`. Data is streamed in large blocks to avoid excessive memory use.
Array objects are returned as instances of `java.sql.Array`.
Methods added in Java 8 are supported and the behaviour of the `getObject(int columnIndex)` method for retrieving TIMESTAMP WITH TIME ZONE has changed. In versions before 2.4.0, this method returned a `java.sql.Timestamp` object. It now returns a `java.time.OffsetDateTime` object which contains the time zone offset value as well as the other fields of the TIMESTAMP.
A new method, `getObject(int columnIndex, Class<T> type)` is available. With this method, you specify the required return type. The common types such as String, Integer, byte[] are supported, as well as new types that can be used for DATE, TIME, TIMESTAMP, and INTERVAL values. The table below shows which Java classes are the most appropriate for the specified SQL TYPES. In addition, you can use these Java types for values of SQL type that are not fully matched. For example, `java.time.LocalDateTime` can be used to retrieve a DATE value.
<table id="e1">
<tr><td>java.util.UUID = UUID</td></tr>
<tr><td>java.time.LocalDate = DATE</td></tr>
<tr><td>java.sql.Date = DATE</td></tr>
<tr><td>java.time.LocalTime = TIME</td></tr>
<tr><td>java.sql.Time = TIME</td></tr>
<tr><td>java.time.LocalDateTime = TIMESTAMP</td></tr>
<tr><td>java.sql.Timestamp = TIMESTAMP</td></tr>
<tr><td>java.time.OffsetTime = TIME WITH TIME ZONE</td></tr>
<tr><td>java.time.OffsetDateTime = TIMESTAMP WITH TIME ZONE</td></tr>
</table>

Therefore, if TIME '12:00:00' is stored in the database, all users in different time zones will get '12:00:00' when they retrieve the value as a string.
HyperSQL SQL Language
To change the SQL session time zone displacement, use the following commands:
`SET TIME ZONE <time displacement>`
`SET TIME ZONE LOCAL`
The first command sets the displacement to the given value. The second command restores the original, real time zone displacement of the session.
**Datetime Values and Java**
When datetime values are sent to the database using the `PreparedStatement` or `CallableStatement` interfaces, the Java object is converted to the type of the prepared or callable statement parameter. This type may be DATE, TIME, or TIMESTAMP (with or without time zone). The time zone displacement is the time zone of the JDBC session.
When datetime values are retrieved from the database using the `ResultSet` interface, there are two representations. The `getString(...)` methods of the `ResultSet` interface, return an exact representation of the value in the SQL type as it is stored in the database. This includes the correct number of digits for the fractional second field, and for values with time zone displacement, the time zone displacement. </excerpt>

<excerpt>citeturn0search0 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; HSQLDB fully supports datetime and interval types and operations, including all relevant optional features, as specified by the SQL Standard since SQL-92. ... Any zone name used must match exactly a TimeZone id supported by the JVM. ... When datetime values are sent to the database using the `PreparedStatement` or `CallableStatement` interfaces, the Java object is converted to the type of the prepared or callable statement parameter. ... HyperSQL version 2.7 supports some extensions to the SQL standard treatment of datetime and interval types.
If `AT TIME ZONE` is used with a datetime operand of type WITHOUT TIME ZONE, the operand is first converted to a value of type WITH TIME ZONE using the session's calendar, then the specified time zone displacement is set for the value. Therefore, in these cases, the final value depends on the time zone of the session in which the statement was used, calculated at the exact point of time (of the input) and accounting for daylight saving time at that point of time.
From version 2.7.0 it is possible to use regional time zones with AT TIME ZONE. Any zone name used must match exactly a TimeZone id supported by the JVM. These include names such as 'America/New_York'. Some zones include daylight saving time periods which are used when converting the time zone.
See also the FROM_TZ function which allows you to convert to a time zone without changing the date-time values such as hour and minute.
AT TIME ZONE, modifies the field values of the datetime operand. This is done by the following procedure:
1. determine the corresponding datetime at UTC using the session's calendar.
2. find the datetime value at the given time zone that corresponds with the UTC value from step 1.
Example a:
VALUES TIMESTAMP'2022-03-28 11:00:00' AT TIME ZONE INTERVAL '-5:00' HOUR TO MINUTE
C1
------------------------
2022-03-28 14:00:00-5:00
VALUES TIMESTAMP'2022-03-28 11:00:00+4:00' AT TIME ZONE 'America/Chicago'
C1
------------------------
2022-03-28 02:00:00-5:00
`SET TIME ZONE <time displacement>`
`SET TIME ZONE LOCAL`
The first command sets the displacement to the given value. The second command restores the original, real time zone displacement of the session.
Datetime Values and Java
When datetime values are sent to the database using the `PreparedStatement` or `CallableStatement` interfaces, the Java object is converted to the type of the prepared or callable statement parameter. This type may be DATE, TIME, or TIMESTAMP (with or without time zone). The time zone displacement is the time zone of the JDBC session.

This includes the correct number of digits for the fractional second field, and for values with time zone displacement, the time zone displacement.

## Functions to Report the Time Zone.
### TIMEZONE
`TIMEZONE()`
Returns the current time zone displacement for the session. This value is the same as SESSION_TIMEZONE if the user has not changed the TIME ZONE of the session. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
### SESSION_TIMEZONE
`SESSION_TIMEZONE()`
Returns the initial (default) time zone displacement for the current session. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
### SESSIONTIMEZONE
`SESSIONTIMEZONE()`
Returns the same value as SESSION_TIMEZONE. (HyperSQL)
### DATABASE_TIMEZONE
`DATABASE_TIMEZONE()`
Returns the time zone displacement for the database engine. This is based on where the database server process is located. Returns an INTERVAL HOUR TO MINUTE value. (HyperSQL)
### DBTIMEZONE
`DBTIMEZONE()`
Similar to DATABASE_TIMEZONE. Returns a string. Works in ORA compatibility mode only.(HyperSQL)
## Functions to Report the Current Datetime
### CURRENT_DATE
`CURRENT_DATE`
### CURRENT_TIME
`CURRENT_TIME [ ( <time precision> ) ]`

<excerpt>citeturn0search3 [wordlim: 200] Published: 2.0 years ago; Crawled: 2.0 years ago; For example, United Nations designates 5 June as World Environment Day, which was observed on DATE '2008-06-05' in different time zones. ... For example, a database for college course timetables usually stores class dates and times without time zones. ... Any zone name used must match exactly a TimeZone id supported by the JVM. ... 2. find the datetime value at the given time zone that corresponds with the UTC value from step 1. ... `EXTRACT ({YEAR | MONTH | DAY | HOUR | MINUTE | SECOND | TIMEZONE_HOUR | TIMEZONE_MINUTE | DAY_OF_WEEK | WEEK_OF_YEAR } FROM {<datetime value> | <interval value>})` ... At the time of invocation, the Java method is called and the returned `ResultSet` is transformed into an SQL table.
An interval type has all the datetime fields in the specified range. These fields are similar to those in the TIMESTAMP type. The differences are as follows:
The first field of an interval value can hold any numeric value up to the specified precision. For example, the hour field in HOUR(2) TO SECOND can hold values above 23 (up to 99). The year and month fields can hold zero (unlike a TIMESTAMP value) and the maximum value of a month field that is not the most significant field, is 11.
The standard function `ABS(<interval value expression>)` can be used to convert a negative interval value to a positive one.
The literal representation of interval values consists of the type definition, with a string representing the interval value inserted after the word INTERVAL. Some examples of interval literal below:
INTERVAL '145 23:12:19.345' DAY(3) TO SECOND(3)
INTERVAL '3503:12:19.345' HOUR TO SECOND(3) /* equal to the first value */
INTERVAL '19.345' SECOND(4,3) /* maximum number of digits for the second value is 4, and each value is expressed with three fraction digits. The individual fields of both datetime and interval values can be extracted using the EXTRACT function. The same function can also be used to extract the time zone displacement fields of a datetime value.
`EXTRACT ({YEAR | MONTH | DAY | HOUR | MINUTE | SECOND | TIMEZONE_HOUR | TIMEZONE_MINUTE | DAY_OF_WEEK | WEEK_OF_YEAR } FROM {<datetime value> | <interval value>})`
The dichotomy between interval types based on seconds, and those based on months, stems from the fact that the different calendar months have different numbers of days. For example, the expression, “nine months and nine days since an event” is not exact when the date of the event is unknown. It can represent a period of around 284 days give or take one. SQL interval values are independent of any start or end dates or times. However, when they are added to or subtracted from certain date or timestamp values, the result may be invalid and cause an exception (e.g. adding one month to January 30 results in February 30, which is invalid).
JDBC has an unfortunate limitation and does not include type codes for SQL INTERVAL types. Therefore, for compatibility with database tools that are limited to the JDBC type codes, HyperSQL reports these types by default as VARCHAR. You can use the URL property hsqldb.translate_dti_types=false to override the default behaviour.
Java 8 Extensions
JAVA 8 does not have SQL type codes for INTERVAL types. HyperSQL supports `java.time` types for INTERVAL types in `ResultSet`, `PreparedStatement` and `CallableStatement`.
* The `getObject(int columnIndex, Class type)` method on an INTERVAL supports the `java.time.Period` type for YEAR and MONTH interval and the `java.time.Duration` type for other interval types that cover DAY to SECOND.
* The `setObject(int columnIndex)` method accepts `java.time.Period` and `java.time.Duration` objects for columns of relevant INTERVAL types.
* The `getObject` and `setObject` methods with column name parameters behave just like their counterparts …[truncated]</excerpt>

Return a ZoneId-compatible value for HSQLDB timezone detection.
VALUES CURRENT_TIMESTAMP returns a timestamp with time zone, not a timezone identifier. The inherited parser passes its string value to ZoneId.of, so detection can fail and TableReaderJdbcBase falls back to defaultTimeZone. For an unconfigured HSQLDB reader with a datetime offset, that fallback controls the generated incremental bounds and can read the wrong range when it differs from the database timezone.
Use an HSQLDB query that returns the database timezone displacement formatted as a ZoneId-accepted offset, or add an HSQLDB-specific parser for that displacement before constructing the ZoneId.

Update getServerTimezoneQuery or add an HSQLDB-specific parser so timezone
detection yields a displacement formatted as a value accepted by ZoneId.of,
rather than a timestamp; preserve the detected database timezone for incremental
bounds when no timezone is configured.
