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.

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.

However the same code works fine in development. I need to know when can one have ORA-01001: invalid cursor in an update query. I did some googling and found that there are two possibilities of getting this error: Numbers of cursors opened becomes greater than MAXCURSOR permitted? An attempt ora-01001 invalid cursor to fetch is made without opening a cursor. Has anyone faced the same problem I had described above? Please suggest solutions. sql oracle share|improve this question edited Mar 5 '10 at 15:38 OMG Ponies 199k37361417 asked Mar 5 '10 at 8:04 Sachin Chourasiya 4,877196487 What version of Oracle? –DCookie Mar 5 '10 at 16:20 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote Yes, these are the common causes (see also this if you don't have already). Considering you are using two different environments (dev/prod) have you verified that the MAXCURSOR parameter is the same (or that Prod MAXCURSOR > Dev MAXCURSOR)? You should also investigate your batch process and see if the number of data could cause your process to open more cursor in prod. Example: your batch launches a stored procedure for every department code in a departments table, and every instance of this procedure opens N cursors. If you have - say - 3 dep. codes in dev because it is enough for your tests, and 34 department codes in Prod, you could use 10 times the cursor and get in the same situation... share|improve this answer answered Mar 5 '10 at 8:23 p.marino

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.
