A_DB2_USE_SQLCOLUMNS configuration variable

Restriction: This topic applies only when a Database Connectors license has been installed via the Micro Focus License Management System, and applies to Windows platforms only.

For some large databases, the API function SQLColumns(), which is called to get a description of the columns in a table, sometimes takes a long time to execute. If you are experiencing such problems, you can use the API function call SQLDescribeCol() instead, which can improve performance for large databases.

To turn on this new functionality, set A_DB2_USE_SQLCOLUMNS to FALSE. The default value for this variable is TRUE.
