Question

I have a table AssignmentMaster in that I have following columns with data

AssignmentID         PaidAmount     RefundAmount   UserID
1                     20               0               1
2                     10               5               1
3                     30               7               2
4                     25               0               3
5                     35               15              3
6                     10               3               1
7                     5                0               3
8                     10               0               3

Now I want to find out the TotalNumberofAssignment with respect to userID, i.e. result should be:

UserID  TotalAssignment  TotalAssignmentofRefundAmount  TotalPaidAmount TotalRefundAmount
1               3                    2                       40               8
2               1                    1                       30               7
3               4                    1                        75              15

How I can get above given result in MSSQL.
your any help will help me lot.

Answer 1

SELECT
   UserID,
   COUNT(AssignmentID) AS TotalAssignment,
   SUM(SIGN(RefundAmount)) AS TotalAssignmentofRefundAmount,
   SUM(PaidAmount) AS TotalPaidAmount,
   SUM(RefundAmount) AS TotalRefundAmount
FROM
   MyTable
GROUP BY
   UserID

Note:

SIGN(RefundAmount) works if RefundAmount is always >= 0.

If not, change to

SUM(CASE WHEN RefundAmount <> 0 THEN 1 ELSE 0 END) AS TotalAssignmentofRefundAmount
