SQL查询根据ID返回字段的总和

Question

In the top picture is what I have in the SQL Table.

I have this Query that gives me the result in the bottom gridview. The query will return in The TransTypeDesc Column the largest EstimatedTransTime. As you can see Car is the largest EstTransTime in Q1.

The only thing that I dont have is the TotalEstimatedTransTime based on the DisplayNum. So for Q1 I should have 31 min.

  SELECT t1.DisplayNum, t1.TransTypeDesc, t1.SubQueueId, t1.EstimatedTransTime 
  FROM vwQueueData AS t1 
  LEFT OUTER JOIN vwQueueData AS t2 ON t1.DisplayNum = t2.DisplayNum AND t1.EstimatedTransTime < t2.EstimatedTransTime 
  WHERE (t2.DisplayNum IS NULL) AND (t1.Called IS NULL) AND (t1.SubQ = @SubQ) 

HERE IS THE SQL Fiddle : http://sqlfiddle.com/#!3/a8983/1

You need to do something as per below:

SELECT t1.DisplayNum, t1.TransTypeDesc, t1.SubQueueId, SUM(t1.EstimatedTransTime) 
FROM vwQueueData AS t1 
LEFT OUTER JOIN vwQueueData AS t2 
     ON t1.DisplayNum = t2.DisplayNum AND 
        t1.EstimatedTransTime < t2.EstimatedTransTime 
WHERE (t2.DisplayNum IS NULL) AND 
      (t1.Called IS NULL) AND (t1.SubQ = @SubQ)
GROUP BY t1.DisplayNum, t1.TransTypeDesc, t1.SubQueueId

Basically, add the SUM function to the 'EstimatedTransTime' column. Then perform a group by on the DisplayNum column in order to get the desired output.
