Execution failed https://www.techonthenet.com/oracle/errors/ora01001.php 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) http://stackoverflow.com/questions/11341166/strange-error-ora-01001-invalid-cursor-in-procedure 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?

The description for that is 'ORA-6504 raised when sys_refcursor passed to another procedure', but I can make that happen too if I change test_fail to do
2 ORA-01001: invalid cursor TweetSumoMe Tweet ORA-01001: invalid cursor error occurs when you tried to reference a cursor that does not yet exist. A few scenarios given below. 1.

When you use FOR LOOP for iteration no need of Explicit use of FETCH..,OPEN… and CLOSE cursor invalid cursor statements.
