Failed to parse the MySQL query error #263
Description
When importing a WordPress MySQL dump, I’m getting an error when executing wp sqlite import dump.sql, which parses the file into multiple queries and then calls driver->query($statement) for each statement. The SQLite import command is parsing the query incorrectly, and then the SQLite driver throws an error.
I wonder if there is a built-in parser in the SQLite plugin or if we could pass and execute multiple statements together instead of one by one.
Here is the related code:

Example Query:
/*M!999999\- enable the sandbox mode */
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8mb4 */;

@JanJakes , do you have any input about the MySQL parser?
JanJakes commentedon Oct 8, 2025
@sejas The parser can do it, but the driver itself expects to process the queries one by one at the moment. From the outside, it's usable as follows:
I think this is a quick and reasonable fix on the WP CLI SQLite command side for now.

@JanJakes , I created this PR Automattic/wp-cli-sqlite-command#13
I had to remove all the comments with a regex because the AST parser was identifying them as queries to execute, which caused it to fail. For example
Error: SQLite import could not execute statement: SET @saved_cs_client = @@character_set_client */;
