Notes
See also DBCursorRowCount.
Database/ERP functions emulate Structured Query Language (SQL) database operations. Before you use these functions, familiarize yourself with how SQL statements are formed and executed.
You can use the Database Gateway (StADOSvr) to directly monitor database connections for leaks and errors. For more information, see Database Interface.
