Question

This is probably something very simple, so forgive my blonde moment 🙂

I have a table ‘album’

* albumId
* albumOwnerId (who created)
* albumCSD (create stamp date)

Now what I am trying to do is to select the top 10 most recently updated albums. But, I don’t want 10 albums from the same person coming back – I only want one album per unique person. I.E 10 albums from 10 different people.

So, this is what I have below, but it is not working properly and I just can’t figure out why. Any ideas?

Thanks

SELECT DISTINCT(albumOwnerId), albumId
FROM album
ORDER BY albumCSD DESC
LIMIT 0,10

Here is some example data, followed by what I am trying to get. Hope this makes it clearer.

Answer 1

I get results, you want to have, with this query

SELECT albumOwnerID, albumId, albumCSD
FROM album
WHERE albumCSD in
(SELECT  Max(album.albumCSD) AS MaxvonalbumCSD
FROM album
GROUP BY album.albumOwnerID);

However in MS Access
