Your problem is at the end of you OleDbCommand

u.U_id= " + userid, s.U_id = " + userid,ss.U_id=" + userid, con);

You need some extra quotation marks in there - I think it should be

u.U_id= " + userid + ", s.U_id = " + userid + ",ss.U_id=" + userid, con);

I suspect you'll then probably end up with a sql error but at least your code will compile
