hello i need to pick data (usernames and passwords)from a normal html form and then query the database from inside a servlet to return the password stored in userDetails table for the submitted username after which i compare the two and allow or deny login. The problem if i store the submitted user name in a variable String uname = username.getSstring(); can i write the query as say select passwd from userDetails where UserID = uname remember uname is not the actual value, but just a variable storing the actual username. thanks alot. any help is really appreciated. richard.    More>>
