Description When you encounter an ORA-01001 error, sql error invalid cursor halt application the following error message will appear: 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.

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 http://stackoverflow.com/questions/11341166/strange-error-ora-01001-invalid-cursor-in-procedure 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?

Join them; it only takes a minute: Sign up ORA-01001 Invalid cursor error up vote 0 down vote favorite I have written two database procedures in Oracle that are using multiple cursors. The problem faced is that while the procedures are getting executed without any errors in 98% of the ora-01001 invalid cursor cases, for few cases, the error - ORA-01001 invalid cursor is being thrown. Since the problem occurs at runtime, it is getting difficult to identify the cause. I am unable to replicate the scenario wherein the procedure throws the error. As per my understanding, since 98% of the cases are executing both the procedures without any problem, I don't think the cause is due to invalid Open-Fetch-Close commands. Any idea what could be the possible reason for the exception being thrown? I am adding a sample code: CURSOR curWork(vCaseId VARCHAR2) IS SELECT w.X_WORKFUNCTION_ID FROM table_case c, table_queue w WHERE c.id_number = vCaseId AND c.CASE_CURRQ2QUEUE = w.objid; CURSOR curPart(vCaseId VARCHAR2) IS SELECT p.x_part_number, p.X_FAULT_CATEGORY, p.X_FORW_GRP_ID FROM table_case c, table_mod_level m, table_x_part_forw_grp p, table_part_num n WHERE c.id_number =vCaseId AND c.CASE_PRT2PART_INFO =m.objid And m.part_info2part_num=N.OBJID AND N.S_PART_NUMBER=P.X_PART_NUMBER; PROCEDURE UpdateAddressXY(vCaseId IN VARCHAR2, nStatus IN OUT NUMBER, vComment OUT VARCHAR2) IS bContinue boolean; nJobCode VARCHAR2(4); cnt number; CURSOR curAddress(vCaseId VARCHAR2) IS select a.X_COORDINATE_X , a.X_COORDINATE_Y, A.X_XY_ORIGIN from table_address a, table_case c

This usually means that 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. Either a host language program 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 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. Note that the ORA-01001 error does not exist in Oracle 10g.. 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 be necessary to increase the MAXOPENCURSORS option value before precompiling. There haven't been any comments added for this error yet.
