You've executed a CLOSE cursor before OPENING the cursor. You've executed a FETCH cursor after CLOSING the cursor. Resolution The option(s) to resolve this Oracle error are: Option #1 Make sure you haven't CLOSEd the cursor and are still referencing it in your code. Option #2 Make sure you've OPENed the cursor before calling a FETCH cursor or CLOSE cursor. Option #3 If everything else is fine, you may need to increase the AREASIZE and MAXOPENCURSORS options.

noticed that the cursor has been closed and have tried to continue using it. The following checklist may help identify the fault: Make sure you have https://www.techonthenet.com/oracle/errors/ora01001.php an OPEN statement prior to using any explicit cursors. Make sure that you do not have a misplaced CLOSE statement. If you need to do a sequence of OPEN...CLOSE...OPEN...CLOSE (perhaps because you need to reset bind variables or to commit updates inside a loop) check your logic flow and make sure there are http://www.orafaq.com/wiki/ORA-01001 no fetches between the 1st CLOSE and the 2nd OPEN. If you have nested loops, check that a condition in an inner loop is not being missed which allows control to pass unexpectedly to a CLOSE in an outer loop Remember that a PL/SQL FOR loop does an implicit OPEN and CLOSE. If you take a routine with a FOR loop and change it to a WHILE loop you must remember to code the OPEN and CLOSE.
