Arvind,

You probably need to look into "Explain Plans" or "Tracing" since they both show what objects are used in queries. Explain Plans are useful to see what a query is likely to do, Tracing is useful when you don't have access to the queries or suspect that what the query is doing will be different to what the explain plan says. There are many, many tools to help you achieve this goal - try www.orafaq.net/tools perhaps.

Also, I am curious why someone working at a company called "SQL Star International" has to go to a list to find this answer?
