Question

I have a table, links1, that has the columns headers CardID and AbilityID, that looks like this:

CardID | AbilityID
1001   | 1
1001   | 2
1001   | 3

1002   | 2
1002   | 3
1002   | 4

1003   | 3
1003   | 4
1003   | 5

What I want is to be able to return all the CardID that that have two specific AbilityID.

For example:

If I choose 1 and 2, it returns 1001.
If I choose 3 and 4, it returns 1002 and 1003.

Is it possible to do this with only one table, or will I need to create an identical table and do an INNER JOIN on those?

Answer 1

Try self join:

SELECT t1.CardID 
FROM links1 AS t1 
JOIN links1 AS t2 
ON t1.CardID = t2.CardID 
WHERE t1.AbilityID = 1 AND t2.AbilityID = 2;
