<-- Anonymously Posted: Tuesday, June 26, 2012 02:02 --> Hi Experts, Is there a way where I can run the below Update statement faster UPDATE T1 SET c1 =? T2.c1 WHERE T1.c2 = T2.c2; When I am running the above update for 10000 records it comes out in 5 secs. However, when I am running the same statement for 430000 records it does not come out even in 40 mins. (I already collected the stats on column c2 for T1 & T2) I am afraid the time would be much more if we run this on the production. Can somebody please help me with the resolution please. Many thanks in advance?
