Updating using cursor oracle

DBMS_OUTPUT.put_line(l_tab.count

From Oracle 10g onward, the optimizing PL/SQL compiler converts cursor SET SERVEROUTPUT ON DECLARE TYPE t_bulk_collect_test_tab IS TABLE OF bulk_collect_test%ROWTYPE; l_tab t_bulk_collect_test_tab; CURSOR c_data IS SELECT * FROM bulk_collect_test; l_start NUMBER; BEGIN -- Time a regular cursor for loop.

Bulk binds can improve the performance when loading collections from a queries.

The SET SERVEROUTPUT ON DECLARE TYPE t_bulk_collect_test_tab IS TABLE OF bulk_collect_test%ROWTYPE; l_tab t_bulk_collect_test_tab := t_bulk_collect_test_tab(); l_start NUMBER; BEGIN -- Time a regular population.

All procedural code is handled by the PL/SQL engine while all SQL is handled by the SQL statement executor, or SQL engine.

There is an overhead associated with each context switch between the two engines.

Oracle9i allows us to use Record structures during bulk operations so long as we don't reference individual columns of the collection.
