Optimizes memory consumption when using Oracle, PostgreSQL,
or
DB2 providers. Also applies the same data integrity rules on all databases for embedded SQL cursors that use WITH HOLD and
FOR UPDATE clauses for
DBMAN=ODBC.
Syntax:
OPTIMIZECURSORS={YES|NO}
Parameters:
- YES
- Optimize cursors. This can result in considerable memory savings and performance gains for large result sets, and also ensures
that SQL cursors that use WITH HOLD and FOR UPDATE clauses have appropriate database locks when positioned updates/deletes
occur.
- NO
- Provided for backward compatibility. Sets the behavior to that of
Visual COBOL versions before 3.0.
Dependencies:
To use OPTIMIZECURSORS, you must set DBMAN to
ODBC explicitly, or by setting an SQL compiler directive option that sets DBMAN to
ODBC implicitly.
