Is possible to use Group by ?

[dmstole]

I try to use group by equal in SQL Language, like that:

SELECT
        COUNT(1) AS TOTAL,
        [System.Tags]
FROM workitems
WHERE [System.TeamProject] = @project
GROUP BY [System.Tags]
ORDER BY [System.ChangedDate] DESC

No, but for that example you could just call the tags api directly to get the list of all tags.
