hi,
I am new to SQL server. Consider I have 6/7 application and one application is very slow.
how I can find out which application is slow and why?
Also how I can find out which query is running slow?

Profiler is a tool that captures the events / query on the server.

Try and trap what you define as a slow running query (or maybe a fast running query that repeats often) analyse the execution plan .
