Question

I’m trying to figure out how I can select all active users that does not have a workgroup set.

I have the user table with the col active (1=true) to see if the user is active. BUT, one user can have multiple “roles” in the system, and each of the roles has a set of settings.

Workgroup is a setting in the userrolesetting, its ID is 1000. I want to get all users that is missing the workgroup or where the workgroup is null.

I’ve trying to go with:

SELECT *
FROM user U
INNER JOIN userrole R
ON R.uid = U.uid
INNER JOIN userrolesetting S
ON R.rid = S.rid
WHERE U.active = 1

This is totally nonsence, but I’m really confused on how to attack it.

Answer 1

Try the following:

SELECT *
  FROM USER u
  INNER JOIN USERROLE r
    ON (r.UID = u.UID)
  LEFT OUTER JOIN USERROLESETTING s
    ON (s.RID = r.RID AND
        s.ID = 1000)  -- may be the wrong column name - change as needed
  WHERE u.ACTIVE = 1 AND
        s.RID IS NULL

Share and enjoy.
