Question

If I have a table named USER and I have 3 columns user_name, user_password and user_surname, with user_name and user_password set as the primary key. When a user log into the program they are required to enter there name and password.

Now I need to verify this combination, so I need to know if I can do pair-wise comparison like the following:

SELECT * 
FROM user
WHERE (user_name, user_password) = ('&name', '&password');

I know that you can use pair-wise comparison like the above with a IN but do not know if you can use it with =. The thing is that the user needs to enter the two values (name, password) and then it needed to be checked in the table.

Please I need advice

Answer 1

In T-Sql, we use

Select * 
From User 
Where User_Name = @Uname AND Password = @Passwd

Your sort of comparison is not possible , I think.

Since you are using Access

Select * 
From User 
Where User_Name = ? AND Password = ?
