call specified an invalid cursor or the value of the MAXOPENCURSORS option in the precompiler command were too small. All cursors must be opened using the OOPEN call before being referenced in any of the following java.sql.sqlexception: ora-01001: invalid cursor calls: SQL, DESCRIBE, NAME, DEFINE, BIND, EXEC, FETCH, and CLOSE. The Logon Data Area (LDA) must be defined by using OLON or OLOGON. If the LDA is not defined, this message is issued for the following calls: OPEN, COM, CON, ROL, and LOGOFF. Action: Check the erroneous call statement. Specify a correct LDA area or open the cursor as required. If there is no problem with the cursor, it may ora-01001 invalid cursor for loop be necessary to increase the MAXOPENCURSORS option value before precompiling. The ORA-01001 error occurs when: a host language program call gave an invalid cursor for use the value of the MAXOPENCURSORS option in the precompiler command was too small You can fix the ORA-01001 error by: Check your problematic call statement for any issues Specify a correct LDA area or open the cursor as required As a last resort, increase the MAXOPENCURSORS option value before precompiling As a note, the ORA-01001 error does not exist in Oracle 10g, according to the Oracle documentation. OraFaq.com has the following to say about the ORA-01001 error: This is 100% a program logic problem. You have either forgotten to code an open statement before using a cursor, or have not 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 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 no fetches between the 1st C

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 http://stackoverflow.com/questions/11341166/strange-error-ora-01001-invalid-cursor-in-procedure 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? Oracle v
already been closed. How to fix it[edit] This is 100% a program logic problem http://www.orafaq.com/wiki/ORA-01001 (unless an Oracle bug, such as bug 6823287). Mostly, you will have either forgotten to code an open statement before using a cursor, or have not 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 invalid cursor 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 ora-01001 invalid cursor 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.
