When we want to issue a lock over the record set returned by the cursor associated SELECT query, we can opt for the FOR UPDATE clause, which automatically places an exclusive row-level lock on all the rows retrieved, forbidding any other session from performing a DML operation on them until we perform a commit or a rollback to release the lock.
