create indexes on tabb; Don DECLARE CURSOR a_cur IS SELECT b.*, a.new_id AS a_new_id FROM tabb b, (SELECT old_id, new_id, ROW_NUMBER() OVER (PARTITION BY old_id) AS rw FROM taba) a WHERE b.old_id = a.old_id AND rw = 1; TYPE tb_array IS TABLE OF a_cur%ROWTYPE INDEX BY PLS_INTEGER; tb tb_array; BEGIN OPEN a_cur; LOOP FETCH a_cur BULK COLLECT INTO tb LIMIT 10000; FORALL ndx IN 1.

It took 9 hrs still didnt complete the task update tabb b set new_id = (select new_id from taba a where a.old_id = b.old_id and rownum = 1) where exists (select 1 from taba a where a.old_id = b.old_id) tab b has 56,329,975 records tb a has 699075 records . Please help You should try to update the inline view-join between a and b with? You don't mind waiting (possibly a long time) for this transaction to either complete successfully or fail completely. If it doesn't, I would suggest a different approach: start with a cursor loop from the smaller table, then update the matching rows in tabb for each row selected from taba.
