Question

I have the following SQL sp and I would like to add a column ‘NetSales’ which is simply ‘GrossSales’ – ‘Credits’. Is there a way to do this in the same SELECT statement?

SELECT p.PerceptionistID, p.BaseCommission, p.BonusCommission, h.WeekOf, h.WorkHours, h.PTOHours, h.HolidayHours,
    ROUND(h.WorkHours, 0) AS HoursRounded, 
    (
        SELECT COUNT(c.PerceptionistID)
        FROM T_Call c 
        WHERE 
            c.PerceptionistID = p.PerceptionistID 
            AND c.OutcomeID = @OutcomeSale 
            AND EnteredOn BETWEEN @WeekOf AND DATEADD(dd, 7, @WeekOf)
    ) AS GrossSales,
    (
        SELECT COUNT (c.PerceptionistID)
        FROM T_CallCredit cc
            FULL JOIN T_Call c
                ON cc.CallID = c.CallID
        WHERE 
            c.PerceptionistID = p.PerceptionistID 
            AND cc.CallCreditStatusID NOT IN (17, 18)  -- 17 - 'Error in Customer Account', 18 - 'Courtesy Credit'
            AND cc.EnteredOn BETWEEN @WeekOf AND DATEADD(dd, 7, @WeekOf)
    ) AS Credits

    --------------------------------------------------
    -- would like to have something like the following

    SUM(GrossSales - Credits) AS NetSales


FROM T_Perceptionist p
    FULL JOIN T_PerceptionistHours h
        ON p.PerceptionistID = h.PerceptionistID
WHERE h.WeekOf = @WeekOf

TIA, Brian

Wrap the whole query with another like this:

select *, a.GrossSales - a.Credits as NetSales
from (
    --your query here
) a
