Bulk binds enable a PL/SQL program to fetch many rows from a cursor in one call instead of fetching one row at a time.

The same goes for a program that issues five or six UPDATE statements.1) It runs forever because there is no EXIT from your loop.I met Alice, Gary and their three kids at a Caribbean resort.Even so, it is very rare that a one-night stand evolves into a healthy, long lasting relationship.More often than not, physical intimacy in the very early stages of a relationship diminishes the potential for loving and lasting.There is the famous “third date” rule, but with total strangers, that’s often too soon.

Some relationship experts demand “no sex until monogamy” which can be safe and useful, or feel very transactional: woman trades sex as a reward for man’s pledge of commitment. But when people first meet, the idea that they have differences of opinions, needs and beliefs can be threatening.

Do you or someone you know who is looking for a serious relationship, have affair after affair that lasts anywhere from three days to three months, and can’t figure out why?

While there are many possible reasons, it might be an issue of pacing.

If you have the luxury of time, you can test your code both with and without bulk binds.

A PL/SQL program that reads a dozen rows from a cursor will probably see no noticeable benefit from bulk binds.

Now consider the following excerpts from another TKPROF report: ************************************************************************ DECLARE CURSOR c_orders IS SELECT order_id, currency_code, amount_local /* bulk bind */ FROM open_orders; TYPE t_num_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; TYPE t_char_array IS TABLE OF VARCHAR2(10) INDEX BY BINARY_INTEGER; v_order_ids t_num_array; v_currency_codes t_char_array; v_amounts_local t_num_array; v_amounts_usd t_num_array; v_row_count NUMBER := 0; BEGIN OPEN c_orders; LOOP FETCH c_orders BULK COLLECT INTO v_order_ids, v_currency_codes, v_amounts_local LIMIT 100; EXIT WHEN v_row_count = c_orders%ROWCOUNT; v_row_count := c_orders%ROWCOUNT; FOR i IN 1..v_order_ids.count LOOP v_amounts_usd(i) := currency_convert (v_amounts_local(i), v_currency_codes(i)); END LOOP; FORALL i IN 1..v_order_ids.count UPDATE open_orders /* bulk bind */ SET amount_usd = v_amounts_usd(i) WHERE order_id = v_order_ids(i); END LOOP; CLOSE c_orders; COMMIT; END; call count cpu elapsed disk query current rows ------- ------ -------- ---------- -------- -------- -------- -------- Parse 1 0.03 0.03 0 0 0 0 Execute 1 0.60 0.62 0 0 0 1 Fetch 0 0.00 0.00 0 0 0 0 ------- ------ -------- ---------- -------- -------- -------- -------- total 2 0.63 0.66 0 0 0 1 ************************************************************************ SELECT order_id, currency_code, amount_local /* bulk bind */ FROM open_orders call count cpu elapsed disk query current rows ------- ------ -------- ---------- -------- -------- -------- -------- Parse 1 0.00 0.00 0 0 0 0 Execute 1 0.00 0.00 0 0 0 0 Fetch 303 0.48 0.59 0 4815 0 30286 ------- ------ -------- ---------- -------- -------- -------- -------- total 305 0.48 0.59 0 4815 0 30286 ************************************************************************ UPDATE open_orders /* bulk bind */ SET amount_usd = :b1 WHERE order_id = :b2 call count cpu elapsed disk query current rows ------- ------ -------- ---------- -------- -------- -------- -------- Parse 1 0.00 0.00 0 0 0 0 Execute 303 3.75 8.38 0 30895 31021 30286 Fetch 0 0.00 0.00 0 0 0 0 ------- ------ -------- ---------- -------- -------- -------- -------- total 304 3.75 8.38 0 30895 31021 30286 This code uses bulk binds to do the same thing as the first code sample, but works with data 100 rows at a time instead of one row at a time.
