when i update sitemap table stored in database.

You can use a SQL cache dependency to check when the table is updated.

I have found a couple of good articles about this. SQL Server 2005 is
best as you can specify a refresh when the results of a query change,
rather than just the contents of an entire table.

http://www.devx.com/dotnet/Article/32223/1954?pf=true seems to cover
most of points. It enabled me to get a working dependency set up.
