Question

Below is my exact code as it sits. This query works excellent except for when the teamid does not exist inside the date range. If the teamid does not exist within the date range specified, I want SQL to add the teamid to the table and set its count to 0. Then, my table will automatically convert the teamid to the teamtext for me.

SELECT tn.teamtext, COUNT(referteamID2) AS cnt
FROM teamnames AS tn
JOIN caseaudit AS ca
ON tn.teamID = ca.referteamID2
WHERE CONVERT(smalldatetime,dModLast,101) BETWEEN '2012-03-01' AND '2012-03-10'
AND ca.referteamid1 <> ca.referteamid2
AND teamid IN (99, 107, 124, 27, 31, 44, 110, 43, 57, 50, 46)
GROUP BY tn.teamtext
ORDER BY tn.teamtext

This returns:

4H BOSS                59
ASSET MANAGEMENT       16
BOSS                   5
CUSTOMER SUPPORT       133
NETWORK ENGINEERING    15
PRODUCTION ENGINEERING 142
SECURITY               6
VOICE SERVICES         21
XEROX                  8

I was told that the problem may possibly have something to do with using IN after giving the date constraints.

Answer 1

Move the condition from the WHERE clause to a CASE statement in the SELECT:

SELECT tn.teamtext,
       sum(case when CONVERT(smalldatetime,dModLast,101) BETWEEN '2012-03-01' AND '2012-03-10' 
                then 1 else 0
           end) AS cnt
FROM teamnames AS tn JOIN
     caseaudit AS ca
     ON tn.teamID = ca.referteamID2
WHERE ca.referteamid1 <> ca.referteamid2 AND
      teamid IN (99, 107, 124, 27, 31, 44, 110, 43, 57, 50, 46)
GROUP BY tn.teamtext
ORDER BY tn.teamtext
