How To Solve Ora 01002 Fetch Out Of Sequence
ORA-01002: fetch out of sequence tips Oracle Error Tips by Burleson Consulting ora-01002 fetch out of sequence ref cursor The Oracle oerr utility notes this on the ora-01002 error: ORA-01002: fetch out of sequence Cause: This error means that a fetch has been attempted from a cursor ora-01002 fetch out of sequence ora-02063 preceding line from which is no longer valid.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 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can have multiple causes including: A PL/SQL loop does fetches without notice Attempting to fetch from a cursor that is no longer valid (fetching from a row which has been retrieved).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

Magazine Online 2016 2015 2014 2013 2012 2011 2010 As Published In September/October 2004 TECHNOLOGY: Ask Tom On Fetching, Storing, and Indexing By Tom Kyte Our technologist http://www.oracle.com/technetwork/issue-archive/o54asktom-086284.html fetches sequentially, stores inline, and indexes globally. We've got a problem concerning an ORA-01002 error in a PL/SQL block. We learned that this error sometimes happens under special circumstances when updating selected data, such as 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 fetch out when reading data from a cursor, without 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 fetch out of my_savepoint; for x in c loop -- do some work, but 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 t
