Hi... As you told Why truncate statement is faster than delete statement.
@edurekaIN
5 жыл бұрын
Hi Raja, Delete table is a logged operation. So the deletion of each row gets logged in the transaction log, which makes it slow. Truncate table also deletes all the rows in a table, but it won't log the deletion of each row instead it logs the deal location of the data pages of the table, which makes it faster. Hope this is helpful!
Very nice video.. only.speed was a problem..It was too fast. Thank you!
Very good
