동일한 검색어로 전년도 데이터 사용

Question

다음은 현재 나의 쿼리입니다. 클리닉과 해당 거래별로 그룹화 된 각 회계 기간의 수익을 계산하는 CTE가 있습니다. 개별 클리닉의 근무일을 살펴보고 예상 일수를 기준으로 일일 평균 (현재 날짜 계산) 및 예상 수익을 찾는 쿼리가 이어집니다.

이 쿼리는 정상적으로 작동합니다. 그러나 나는 더 많은 컬럼을 추가 할 필요가있다. 전년도의 수익도 표시하고 싶습니다.이 경우 검색어를 2016 년과 9 기간으로 제한하고 전년도 수익은 2015 년 9 월에 표시해야하며 전년도의 일을 볼 필요가 있습니다 뿐만 아니라 (나는 비슷한 과정이 될 것이라고 생각한다).

WITH CTE_Revenue AS(
SELECT c.Clinic, 
     c.ClinicID, 
     SUM(td.Amount)*-1 AS Revenue, 
     p.PeriodID, 
     p.FiscalYear 
FROM Trans.TransactionHeader th 
JOIN Clinic.[Master] c 
    ON (th.ClinicID = c.ClinicID) 
JOIN Trans.TransactionDetail td 
    ON (th.ClinicID = td.ClinicID AND th.TranNum = td.TranNum) 
JOIN Clinic.EOD e 
    ON (th.ClinicID = e.ClinicID AND th.TranNum BETWEEN e.StartTran AND e.EndTran) 
JOIN Clinic.Period p 
    ON (CAST(e.TimeRan AS date) BETWEEN p.PeriodStart AND p.PeriodEnd) 
AND th.Impacts='C' 
GROUP BY c.Clinic, c.ClinicID, p.PeriodID, p.FiscalYear) 

SELECT w.Clinic, 
     w.Revenue, 
     (w.Revenue/days.CurrentDays) AS DailyAverage, 
     (w.Revenue/days.CurrentDays)*d.PeriodDays AS ProjectedRevenue 
FROM CTE_Revenue w 
JOIN Clinic.Dates d 
    ON (w.ClinicID = d.ClinicID AND w.PeriodID = d.PeriodID AND w.FiscalYear = d.FiscalYear) 
JOIN ( SELECT DISTINCT 
     td.ClinicID, 
     COUNT(DISTINCT td.DateEntered) AS CurrentDays, 
     p.PeriodID, 
     p.FiscalYear 
    FROM Trans.TransactionDetail td 
    JOIN Clinic.Period p 
     ON td.DateEntered BETWEEN p.PeriodStart AND p.PeriodEnd 
    GROUP BY td.ClinicID, p.PeriodID, p.FiscalYear) AS days 
    ON (w.ClinicID = days.ClinicID AND w.PeriodID=days.PeriodID AND w.FiscalYear = days.FiscalYear) 
WHERE w.FiscalYear = 2016 
AND w.PeriodID = 9 

SELECT 문을 결과로 끝 나는 상상, 다음과 같이 보일 것입니다 :

이 쿼리가 완전히 최적화되지 않을 수 있습니다

SELECT w.Clinic, 
     w.Revenue, 
     (w.Revenue/days.CurrentDays) AS DailyAverage, 
     (w.Revenue/days.CurrentDays)*d.PeriodDays AS ProjectedRevenue, 
     PrevYear.Revenue, 
     (PrevYear.Revenue/PrevYear.CurrentDays) AS PYDailyAverage, 
     (PrevYear.Revenue/PrevYear.CurrentDays)*d.PeriodDays AS PYCalculated 

, 난 여전히 SQL에 비교적 새로운 해요. 미리 조언 해 주셔서 감사합니다.
