venubabu123,
the "it doesn't work" really doesn't help us help you.
Please post a short description of your datatables (table names are rarely enough information -- table names, fields with datatype, relationships between the tables etc)
Also having the actual SQL and some example data (you can makeup a generic set of data... just make sure it is something that reflects a real data-set) to work with will allow our membership to help.
Please include any error messages in their entirety (including number, name, description)
