Question

I have a table with contains multiple rows that define “amenities” for a particular resort. I need to return the resortID if there are rows containing whatever “amenOptionID” I define. My issue comes in where I’m looking to see if a resort has two or more amenities. For example:

I want to return resortIDs that have BOTH amenOptionID 1 AND 4. I also do not want duplicate resortIDs. Refer to the image for the table structure. Thanks in advance for any help.

Answer 1

  SELECT `resortID`
   WHERE `amenOptionID`
         IN (1, 4) 
GROUP BY `resortID`
  HAVING COUNT(*) = 2
