I have three table:
Users - Contains username, ID etc...
Permissions - A permission name and ID
Link up table - The user.id and permission.id
If a user.id and a permission.id row exists in the linkuptable the user
have that permission granted.
With the statement below I can see the permissions a user have.
SELECT users.username, permissions.name
FROM users INNER JOIN linkuptable
ON (users.id = linkuptable.userid)
INNER JOIN permissions
ON (permissions.id = linkuptable.permissionid)
WHERE users.username = 'DummyUser'
How do I see the permissions that user DON'T have with a fast SQL statement.
Thus, a NOT the statement for the above SQL statement
