Description

The GETRESULTSET() function returns the workarea number of 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.

GETRESULTSET() will return 0 (zero) if no SQL cursor is currently marked as a resultset. The marker can be cleared from an SQL cursor using the CLEARRESULTSET() function.

Example

function GetExampleCursor
lparameters lcAccountNo
select * from example where account_no = lcAccountNo into cursor curExample
return setresultset("curExample")
 
open database southwind
GetExampleCursor("00050")
? "Returned resultset is in work area #" + ltrim(str(getresultset()))
set sql off
select getresultset()
display all
? "Cleared resultset marker in work area #" + ltrim(str(clearresultset()))
? iif(getresultset() > 0,"Resultset available in work area #" + ltrim(str(getresultset())),;
 "No resultsets available")
?
