Hi friends,
I am running an update query.
It is taking long time. To find the estimated completion time i checked sys.dm_exec_request or sys.dm_exec_session or sp_who2 but there is no clue. It is showing as zero.
can any one help on this please.

Post the query, please. There's a typcial problem that many folks write into their update queries without knowing about it. To summarize the problem, if the UPDATE contains a JOIN, the target table MUST absolutely appear in the FROM clause. Using tablename.columnname is NOT sufficient and that form of UPDATE never appears in Books Online.

There's no estimated completion for queries, that's for things like backups.

No way to tell how long the query will take other than to run it and see.

Hi GailMosnter..

Thanks for the reply. After surfing google i came to know that we can find the estimation time for any update insert or other queries.

We can know the estimated time only for backup and restore.
