Yes, you can do it with a query like this:

Код:

SELECT * FROM accounts WHERE username='username' AND password='thepass'

Obviously, "thepass" is the hashed text the user will input and you compare it with the hashed password stored in your database...

It will return a row if it found the account with that specified username and username (therefore, the login was successful) but if the account wasn't found, it will not return any row (meaning a failed login).
