Using forall and bulk collect - bulk bind performance, PL-SQL Programming

Assignment Help:

Using FORALL and BULK COLLECT Together

You can unite the BULK COLLECT clause with the FORALL statement, in that case, the SQL engine bulk-binds column values incrementally. In the illustration below, if the collection depts has 3 elements, each of which cause 5 rows to be deleted, then the collection enums has 15 elements when the statement completes:

FORALL j IN depts.FIRST..depts.LAST

DELETE FROM emp WHERE empno = depts(j)

RETURNING empno BULK COLLECT INTO enums;
