I would like to know how to have only the AppID that doesn't have 9 and 10 AppExtraID

Thanks!

Solution

  • I see what you are getting at... 

    SELECT DISTINCT AppID
FROM app_extra 
WHERE AppID NOT IN 
  (SELECT DISTINCT AppID from app_Extra 
   WHERE AppExtraID IN (9, 10))

    The inner select will identify all App ID's which have a 9 or a 10 extra. These rows will then be excluded in the main select. Any AppID which is related to 9 or 10 will be eliminated, even if they also have another extra ID.
