Function to clear the marker from an SQL cursor previously marked as a resultset
The CLEARRESULTSET() function clears the marker from an SQL cursor previously marked as a resultset by the SETRESULTSET() function. The SETRESULTSET() function is particularly used in returning a resultset from a stored procedure in SQL client/server applications.
CLEARRESULTSET() will return the workarea number of the SQL cursor from which the marker was cleared, or 0 (zero) if no SQL cursor was marked as a resultset.
