This is not A Correct Approach for a login. This is simple you are Suppose to count the Records that matches the Where Clause and you have included having and Group by clause and that is incorrect. You need a simple statement like this
I Have once gave someone an answer , please search any post by me here on the Forum

Look at this Post and tell me if there is still a problem
