Question

I have table in following structure…

        ReturnID SumbitID Status

          1           1    1 
          1          NULL  2
          2            2   3
          3            3   1
          3            3   1

I want this output…..

        RetunrID TotalAttempt Success
           1        2           1
           2        1           0
           3        2           2

Count Of ReturnID is TotalAttempt, when ReturnID = sumbitID and status =1 Then it count as success…
Thanks in Advance!

Answer 1

Something like this

SELECT
    T.ReturnID
,   COUNT(T.ReturnID) AS TotalAttempt
,   SUM(CASE WHEN T.ReturnID = T.sumbitID AND T.Status = 1 THEN 1 ELSE 0 END) AS Status
FROM dbo.MyTable T
group by T.ReturnID
