A_DB2_USE_CATALOG

Not all data sources support a catalog, or the data sources may return a catalog name that is not useful. The default behavior of the run time is to not use the catalog in the actual SQL queries. This configuration variable lets you modify this behavior.

The default value is FALSE, which causes the catalog portion of the table name to be treated as blank in SQL queries. Setting this variable to TRUE uses the catalog value returned by SQLTables ODBC function subsequent SQL queries.
