New Features

  • Embedded SQL (EXEC SQL) support for PostgreSQL — a full port of Open COBOL ESQL 4J into cobj and libcobj.jar. COBOL programs can now run EXEC SQL ... END-EXEC statements directly, with no separate precompiler or runtime. (#847)
    • Supports CONNECT/DISCONNECT, INSERT/UPDATE/DELETE/SELECT INTO, cursors (DECLARE/OPEN/FETCH/CLOSE, including WHERE CURRENT OF), dynamic SQL (PREPARE/EXECUTE), and COMMIT/ROLLBACK.
    • Host variables, the SQLCA, packed/binary/national/Japanese data types, configurable bulk fetch, and prepared-statement caching.
    • The generated Java is dramatically simpler and more readable than before: each EXEC SQL statement compiles to a single high-level runtime call passing host variables as a typed array, instead of the verbose low-level helper calls of the original implementation.
    • See the ESQL Guide and examples.

Documentation

  • Improved Javadoc comments for the data, common, and user_util modules of libcobj. (#846, #841, #836)
