Performance issue in update query

Question

I have one small doubt in query performance. Basically, I have a table with more than 1C records. sl_id is the primary key in that table. Currently, I am updating t

Answer 1

Definitely IN is more powerful, but again the number of match to check in IN will make performance issue.

So, I will suggest to use IN but with BATCH, as in if you have 200 record to update then part in 50 each and then make 4 UPDATE query, or something like that.

Hope it helps...!!
