Thank You Bhuvnesh for the quick reply,

But it’s difficult to find the table which is not been used more than a month as my server was rebooted since 65 days. If I can get an exact table names so that I can change their names it’s a good thing but when I am not sure with the table name then it will be over work in doing this. So is there any way other than this where I can get the tables info which are not been used more than a month or more.

Thank you in Advance
