SQL Statement - SELECT the inverse of this query

问题

I have this query and i want to select the inverse of what that select.

SELECT Guide.id FROM Guide
INNER JOIN GuideAvailability ON Guide.id = GuideAvailability.guideId
WHERE GuideAvailability.startDate IN (1377946800)
GROUP BY GuideAvailability.guideId
HAVING COUNT(DISTINCT GuideAvailability.id) = 1

Is there a easy way to solve my problem ?

Simply use this query:

SELECT * 
     FROM Guide where id NOT IN (
       SELECT Guide.id 
         FROM Guide
         INNER JOIN GuideAvailability ON Guide.id = GuideAvailability.guideId
         WHERE GuideAvailability.startDate IN (1377946800) 
         GROUP BY GuideAvailability.guideId 
         HAVING COUNT(DISTINCT GuideAvailability.id) = 1
      )

MAy be you are looking for this

SELECT Guide.id FROM Guide
INNER JOIN GuideAvailability ON Guide.id = GuideAvailability.guideId
WHERE GuideAvailability.startDate NOT IN (1377946800) GROUP BY GuideAvailability.guideId HAVING COUNT(DISTINCT GuideAvailability.id) <> 1

You can flip the bool. ;)

I do this when I have a large amount of where filters and there is a specific exclusion set of filters. I write them inside the case and do =1 to exclude and =0 to find what I excluded.

SELECT Guide.id FROM Guide
INNER JOIN GuideAvailability ON Guide.id = GuideAvailability.guideId
WHERE ( case when GuideAvailability.startDate IN (1377946800) then 1 else 0 end) = 0
GROUP BY GuideAvailability.guideId
HAVING COUNT(DISTINCT GuideAvailability.id) = 1
