Purpose
Function to clear the marker from an SQL cursor previously marked as a resultset
Syntax
CLEARRESULTSET()
See Also
GETRESULTSET(), SELECT, SETRESULTSET()
Description
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.
Example
function GetExampleCursor lparameters lcAccountNo select * from example where account_no = lcAccountNo into cursor curExample return setresultset("curExample") open database southwind GetExampleCursor("00050") select * from curexample ? "Cleared resultset marker in work area #" + ltrim(str(clearresultset())) ? iif(getresultset() > 0,"Resultset available in work area #" + ltrim(str(getresultset())),; "No resultsets available") ? close databases
Products
Recital Server, Recital
