SQL Query: Including Two Sums based on different criteria from the same table

Question

I currently have the following sql query

FROM tblTimesheetEntries 
WHERE UserID = \'PJW\' 
AN         


        

Answer 1

You can use a CASE with the SUM() to calculate the separate totals:

SELECT [Date], 
    DATENAME(dw,[Date]) AS Day, 
    sum(case when Chargeable = 1 then Units else 0 end) ChargeableTotal,
    sum(case when Chargeable = 0 then Units else 0 end) NotChargeableTotal,
    sum(Units) AS TotalUnits
FROM tblTimesheetEntries 
WHERE UserID = 'PJW' 
    AND Date >= '2013-01-01' 
GROUP BY [Date] 
ORDER BY [Date] DESC;
