Cross-engine foreign keys support

    XMLWordPrintable

Details

    Description

      Implement cross-engine foreign keys check at SQL layer.

      TODO:

      • Referenced/foreign key lookup procedure
      • Recursive table open (new FK structure for TABLE optimized for DML, FKs in TABLE point to parent TABLEs)
      • Recursive prelocking: write-locking for CASCADE actions
      • DML changes:
        UPDATE, Multi-UPDATE
        DELETE, Multi-DELETE
        REPLACE
        INSERT ODKU
        IGNORE clause
        Ignore ‘DELAYED’
      • DDL changes:
        DROP TABLE (DATABASE)
