Show Zero Values For Missing Data In Query Resultset

Hello,

I have the following query which grabs monthly usage data which is logged to a database table from a web page:


SELECT Button = CASE ButtonClicked

WHEN 1 THEN '1st Button'

WHEN 2 THEN '2nd Button'

WHEN 3 THEN '3rd Button'

WHEN 4 THEN '4th Button'

WHEN 5 THEN '5th Button'

WHEN 6 THEN '6th Button'

WHEN 7 THEN '7th Button'

WHEN 8 THEN '8th Button'

WHEN 9 THEN '9th Button'

ELSE 'TOTAL'

END,

COUNT(*) AS [Times Clicked]

FROM WebPageUsageLog (NOLOCK)

WHERE DateClicked BETWEEN @firstOfMonth AND @lastOfMonth

GROUP BY ButtonClicked WITH ROLLUP

ORDER BY ButtonClicked

The results look like this:

TOTAL 303
1st Button 53
2nd Button 177
3rd Button 10
4th Button 4
6th Button 18
7th Button 19
8th Button 21
9th Button 1

If a button is never clicked in a given month, it never gets logged to the table. In this example, the 5th button was not clicked during the month of December, so it does not appear in the results. I want to modify my query so it displays the name of the button and a zero (in this case "5th Button 0") in the results for any buttons that were not clicked. For some reason I am drawing a blank on how to do this. Thanks in advance.
