I have a view which is created off of another view in same database, when i run the query on the first view the result is fast.

But when i run the query off of second view, It is taking huge amt of time.

Any reason why the second view is taking a lot of time, i am only doing top 100 rows.

Thanks a lot for the helpful info.

Without the definition of either view, plus the underlying tables, and the kinds of queries you're writing against them, there's no way to know. Generally speaking however, nesting view references is not a good idea for performance.

why do you need a separate view for just taking top 100?
