"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which is no longer valid.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 in the SQL statement, then issuing
a fetch before reexecuting 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) Reexecute the statement after rebinding, then attempt to
fetch again.

Oracle Error Tips by Donald Burleson
The Oracle oerr utility notes this on the ora-01002 error:
Cause: This error means that a fetch has been attempted from a cursor which is no longer valid.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 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- Attempting to fetch from a cursor that is no longer valid (fetching from a row which has been retrieved).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)
