How can I amend the below query to get divisor with the same week number (wkno) as dividend based on datetime column of divisor .
SELECT CONVERT(decimal(10, 2), SUM(mAmount) / (SELECT COUNT(*) AS Expr1 FROM Filterednew_appointment WHERE (new_appointmentstatus = 'A') ) ) AS TotalBillSize, WkNo,'O' AS Type FROM (SELECT DISTINCT new_patienthrn AS HRN, new_paidamount AS mAmount, new_name AS BillNo, CASE WHEN (DAY(new_startdate) >= 1 AND DAY(new_startdate) <= 7) THEN 'Wk1' WHEN (DAY(new_startdate) >= 8 AND DAY(new_startdate) <= 14) THEN 'Wk2' WHEN (DAY(new_startdate) >= 15 AND DAY(new_startdate) <= 21) THEN 'Wk3' WHEN (DAY(new_startdate) >= 22 AND DAY(new_startdate) <= 28) THEN 'Wk4' WHEN (DAY(new_startdate) > 28) THEN 'Wk5' END AS WkNo FROM Filterednew_outpatientbillinginfo WHERE (new_patienthrn IS NOT NULL) AND (MONTH(new_startdate) = MONTH(@SDate)) AND (YEAR(new_startdate) = YEAR(@SDate))) AS B GROUP BY WkNo

i didnt get your question clearly. I cant see any datetime column in divisor here. Anyways, if your question was to get weekno from datetime field, use DATEPART() function. Also it gives weekno of the year and not weekno of the month.

Dividend is CONVERT(decimal(10, 2), SUM(mAmount) Divisor is (SELECT COUNT(*) AS Expr1 FROM Filterednew_appointment WHERE (new_appointmentstatus = 'A') )
Divisor has a date time column "new_appointmentdate" but not in query currently. Whole query returns sum group by week no and divided by count returned from divisor (suppose divisor returns 30) Eg. 100/30 wk1 200/30 wk2 But I'd like to change as if divisor has 10 records for wk1 ,divide 100 by 10 if divisor has 20 records for wk2, divide 200 by 20 Calculation of week number will be the same as main query but take "appointmentdate" from divisor table
Thanks.

then change divisor to
SELECT COUNT(DISTINCT DATEPART(wk,new_appointmentdate)) AS Expr1 FROM Filterednew_appointment WHERE (new_appointmentstatus = 'A')
