I have to delete data from live table( Size of DB:terabytes) (system is becoming slow).

without affecting the end users ?

And tables have indexes and identity columns.( when I delete , I don't want to affect the identity columns, how can we do it?)

It is taking lot of time to delete the data.How can i do that?

Any steps to follow.

Thanks
Komal

There is an excellent article on the SQLServerCentral home page today on that very subject:

http://www.sqlservercentral.com/articles/delete/96780/

Be sure to read the discussion on the article, since it has some alternative methods and additional considerations for large volume deletes.



And then again, I might be wrong ...
