Question

I have the following SQL query and so far it works the way it should and gets the top 40 tag ids that I have stored in the tagmap table.

SELECT TOP 40
tbrm_TagMap.TagID,
Count(*)
FROM tbrm_TagMap
GROUP BY tbrm_TagMap.TagID
ORDER BY COUNT(tbrm_TagMap.TagID) DESC

I also want to join to the Tags table which contains the actual name of each TagID. Each attempt I make comes back with an error. How can I achieve this? I am using SQL 2008.

SELECT  *
FROM    (
        SELECT  TOP 40 
                tbrm_TagMap.TagID, COUNT(*) AS cnt
        FROM    tbrm_TagMap
        GROUP BY
                tbrm_TagMap.TagID
        ORDER BY
                COUNT(*) DESC
        ) q
JOIN    Tags
ON      Tags.id = q.TagID
ORDER BY
        cnt DESC
