Description When you encounter an ORA-01001 error, the following error message will appear: sql error invalid cursor halt application ORA-01001: invalid cursor Cause You tried to reference a cursor that does not yet exist. This may have happened because: You've executed a FETCH cursor before OPENING the cursor. 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.

will have either forgotten to code an open statement before using a cursor, or have not increase the area size 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.

Execution failed on statement if v_cursor%isopen then close v_cursor; -- here was an error end if; After some digging into I discovered that problem was in subprogram that opened this cursor. I fixed bug by adding output parameter sys_refcursor in subprogram. To clarify situation consider following test code: procedure nested_test(test number, p_cur out sys_refcursor) is procedure nested_procedure_fail is begin open p_cur for select 1, 2, 3, 4 from dual where 1 = 0; end; procedure nested_procedure_success(p_cur out sys_refcursor) is begin open p_cur for select 1, 2, 3, 4 from dual where 1 = 0; end; begin if test = 1 then nested_procedure_fail; else if test = 2 then nested_procedure_success(p_cur => p_cur); else open p_cur for select 6, 7, 8, 9 from dual where 1 = 1; end if; end if; end; procedure test_fail is v_cur sys_refcursor; begin nested_test(test => 1, p_cur => v_cur); if v_cur%isopen then close v_cur; end if; end; procedure test_success is v_cur sys_refcursor; begin nested_test(test => 2, p_cur => v_cur); if v_cur%isopen then close v_cur; end if; end; If I try to run test_success everything is OK, but on test_fail I receive a message ORA-01001: Invalid cursor I cannot find any information about this. Can anyone explain why this code fails?
