ORA-01002: fetch out fetch out of sequence in oracle cursor of sequence tips Oracle Error Tips by Burleson Consulting The Oracle oerr utility notes this on the ora-01002 error: ORA-01002: fetch out of sequence Cause:Ora-01002 Fetch Out Of Sequence Cursor For Loop
This error means that a fetch has been attempted from a cursor which is no longer valid. Note that a PL/SQL cursor loop implicitly does fetches, and thus may also cause this error. There are a number of possible causes for this error, including: 1) Fetching from a cursor after the last row how to solve ora 01002 fetch out of sequence has been retrieved and the ORA-1403 error returned. 2) If the cursor has been opened with the FOR UPDATE clause, fetching after a COMMIT has been issued will return the error. 3) Rebinding any placeholders in the SQL statement, then issuing a fetch before re-executing the statement. Action: 1) Do not issue a fetch statement after the last row has been retrieved - there are no more rows to fetch. 2) Do not issue a COMMIT inside a fetch loop for a cursor that has been opened FOR UPDATE. 3) Re-execute the statement after rebinding, then attempt to fetch again. ORA-01002 can have multiple causes including: A PL/SQL loop does fetches without notice Attempting to fetch from a cursor that is no longer valid (fetching from a row which has been retrieved). Fetching after a COMMIT has already been issued and a cursor is opened with the FOR UPDATE clause. Issuing a fetch before re-executing a SQ

a PL/SQL block. We learned that this error sometimes happens under special circumstances when updating selected data, such as ora 01002 fetch out of sequence select when using a SELECT for an UPDATE. But this is not the case here. The strange thing is that we're getting this error only when reading data from a cursor, without http://www.dba-oracle.com/t_ora_01002_fetch_out_of_sequence.htm any updates on the cursor data. The error occurs when executing a rollback to a savepoint statement: create table test (a integer); insert into test values (1); create table test2 (b integer); insert into test2 values (11); declare cursor c is select * from test; begin update test2 set b = 22; savepoint my_savepoint; for x in c loop -- do some work, but http://www.oracle.com/technetwork/issue-archive/o54asktom-086284.html if we -- hit an error then: rollback to savepoint my_savepoint; end loop; end; / Our logic is complex; we are processing a result set, and in the loop we have other processing. If we encounter an error, we want to undo all of our work to date. But we've discovered that when we roll back to the savepoint, we always fail with error ORA-01002 "Fetch out of Sequence." We are using Oracle8i Release 3 (8.1.7), and up to now we couldn't find a similar problem in any forum, so any hints are welcome. This makes sense, and, hopefully, you will agree. Your timeline was: At time t0, you did an update—you started a transaction. At time t1, you claimed a "savepoint." At time t1+, you could have modified the database. At time t2, you opened the result set. This result set can see the database "as of time t2, including any and all changes you made in your session—everything that happened from t0 on to t2." You could have modified the table TEST , for example. You didn't, but there is nothing that says you couldn't have

Please help,let me know in case data is also needed for the mentioned table. oracle plsql oracle11g cursor share|improve this question edited Feb 23 '15 at 7:59 Sathya 13.2k1667106 asked Feb 23 '15 at 7:18 Thepallav_abhi 2628 2 Why do you have EXIT WHEN CUR_INTERFACE_EMP%NOTFOUND? A FOR Cursor loop will automatically exit the loop once it's processed all the records, and if the cursor doesn't fetch any records, will not enter the loop at all. Without seeing the full code for FOR loop it's not possible to state what's the problem. Are you doing any deletes/updates om the table referenced in the cursor within the for loop? –Sathya Feb 23 '15 at 7:22 Do you have a commit inside the loop anywhere?

#129976] Wed, 27 July 2005 09:08 lotusdeva Messages: 198Registered: March 2005 Senior Member Hello -- I am not sure if this is some sort of "oracle bug" or an internal program bug. I am getting ORA-01002: fetch out of sequence while trying to commit/rollback inside a cursor. In a nutshell my program is doing the following: 1. Declare a cursor inside package spec: CURSOR c_test(c_id NUMBER) IS SELECT id FROM test_table WHERE id = c_id; 2. Inside package body I open my cursor as follows: OPEN cv FOR lv_stmt; -- this is dynamicaly build string LOOP FETCH cv INTO some variables .. -- I do lots of logic here and call procedure A -- Inside this procedure I preform and insert. -- I get out of this procedure back to the main and -- depending on some additional conditions I either ROLLBACK or -- COMMIT. I perform COMMIT/ROLLBACK inside loop so that it happens per record. Why am I getting fetch out of sequence if the cursor is still open? thanx!

COMMIT in conjunction with this clause causes this problem: SQL> declare 2 cursor s is select ename from emp for update; 3 ename emp.ename%type; 4 begin 5 open s; 6 loop 7 fetch s into ename; 8 exit when s%notfound; 9 ---something 10 commit; 11 end loop; 12 close s; 13 end; 14 / declare * ERROR at line 1: ORA-01002: fetch out of sequence ORA-06512: at line 7 Rgds.

ALthough I understand that commit would essentially close the transaction..so the cursor would be closed. What is the solution then? I absolutelly have to commit per record (or rollback) in several places...
