the ora-01002 error: ORA-01002: fetch out of sequence Cause: This error means that a fetch has been attempted from a cursor which is no longer valid.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 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 how to solve ora 01002 fetch out of sequence 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can have multiple causes including: A PL/SQL loop does fetches without notice Attempting to fetch from a cursor that is no longer valid (fetching from a row which has been retrieved).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 SQL after rebinding placeholders. You may want to try using cursor attributes to dodge ORA-01002 in the future. To resolve a current ORA-01002, there are three actions you can perform: After the last record is received, do not issue a fetch Inside a fetch loop on a SELECT FOR UPDATE, do not use a COMMIT Try fetching again after re-executing the statement (after rebinding) �� <

Ora-01002 Fetch Out Of Sequence Ref Cursor
problem concerning ORA-01002 in a PL/SQL block. As we learned this error sometimes happens ora-01002 fetch out of sequence ora-02063 preceding line from under special circumstances when updating selected data, i.e. when using a select for update. But this is not the case here! ora 01002 fetch out of sequence select The strange thing is that we're getting this error when only reading data from a cursor, without any updates on the cursor data. The error occurs when executing a rollback to savepoint statement: SAVEPOINT my_savepoint; FOR http://www.dba-oracle.com/t_ora_01002_fetch_out_of_sequence.htm my_record IN my_cursor LOOP IF my_condition THEN ROLLBACK TO SAVEPOINT my_savepoint; ELSE do_something; --> no updates on my_cursor; this data is only read --> but: update some other data (without any commit) IF another_condition THEN SAVEPOINT my_savepoint; END IF; END IF; END LOOP; COMMIT; Normally this works fine: if there is still at least one row left to read in my_cursor, there are no problems executing the rollback to savepoint statement. But: https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:18202801725435 If my_record is the last record to be read within my_cursor, and if my_condition equals to true, then the rollback to savepoint statement fails with error ORA-01002! We are using Oracle 8.1.7. Up to now we couldn't find a similar problem in any forum, so any hints are welcome. Thanks. martin Followup: Hello Tom, it took some hours of work to find out what exactly the problem is, but now I've got a little example to reproduce the error: /* --create two tables and insert one row: 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; --this one's new! savepoint my_savepoint; for x in c loop if (true) then rollback to savepoint my_savepoint; else null; end if; end loop; end; / ...leads to "ORA-01002". Seems to be legal PL/SQL for me, so I hope you can help me. Kind regards martin and we said... Ahh, now i see and it makes sense (hopefully you will agree). Ok At time t0, you did an update -- started a transaction At time t1, you claimed "save point" <<<== important At time t1+, you *could have* modified the d

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?
