Answer / Shivram Meena
The ORA-01002 error is often caused by a row that cannot be locked due to concurrency issues. When using FOR UPDATE in Oracle 8, the session locks the rows until the transaction is committed or rolled back. If another session tries to access these locked rows before the original transaction is complete, it will encounter the ORA-01002 error.
