Question

I have a sql table similar to the one below. And I want to bring back unique results where tag_id matches multiple items.
So if I want to find each image_id that has the tag_id = 106 and 73 I would like it to bring back image_id 12345714 and 12345712.

I’ve tried doing

SELECT * 
FROM tag_relationship
WHERE tag_id
IN ( 106, 73 ) 

But this brings back

        id  image_id    tag_id
        61  12345706    73
        70  12345712    73
        72  12345712    106
        76  12345714    73
        77  12345714    106

I’ve also experimented with GROUP BY, but that doesn’t seem to be quite right.

Sample of full table:
image_id can have the same number in different rows, but will have a different tag_id.

       id   image_id    tag_id
        1   12345679    63
        2   12345679    83
        3   12345680    74
        4   12345680    108
