我正在使用SQL Management Studio 2012，我想在表格中选择以下代码，但在使用CTE时从未这样做过。
With UniqueService AS (
SELECT
CASE WHEN LAG(ScheduleOfServiceID,1) OVER (ORDER BY ScheduleOfServiceID ASC, ActualHoursPerWeek ASC) = ScheduleOfServiceID
THEN 0
ELSE 1
END AS UniqueService
,[ClientID]
,[ClientName]
,[ScheduleOfServiceID]
,[ActualHoursPerWeek]
,[ServicePlannedStartDate]
,[ServicePlannedEndDate]
,[ServiceActualStartDate]
,[ServiceActualEndDate]
,[ServiceProvided]
,[ServiceProvider]
,[AllocatedWorkerTeam]
,[StartDateFormatted]
,[SOSStartYearMonth]
,[EndDateFormatted]
,[SOSEndYearMonth]
,[ServicePlacementStartReason]
,[RecordToBeExcluded]
,CASE WHEN EndDateFormatted IN ('')
AND ServiceActualEndDate IS NULL
AND ServicePlannedEndDate IS NULL
THEN NULL
WHEN EndDateFormatted IS NULL
THEN ServiceActualEndDate
WHEN EndDateFormatted IS NULL
AND ServiceActualEndDate IS NULL
THEN ServicePlannedEndDate
ELSE EndDateFormatted
END AS MasterEndDate
FROM [BIPROJECT].[adults].[tAllAdultsDomiciliaryCareReporting]
WHERE RecordToBeExcluded != 1
)
SELECT *,
CASE WHEN ServicePlannedStartDate BETWEEN '2016-04-01' AND '2016-08-31'
AND (MasterEndDate IS NULL
OR MasterEndDate > '2016/08/31')
THEN 1
ELSE 0
END AS ServiceStarted,
CASE WHEN MasterEndDate BETWEEN '2016-04-01' AND '2016-08-31'
AND ServicePlannedStartDate NOT BETWEEN '2016-04-01' AND '2016-08-31'
THEN 1
ELSE 0
END AS ServiceEnded,
CASE WHEN ServicePlannedStartDate BETWEEN '2016-04-01' AND '2016-08-31'
AND MasterEndDate BETWEEN '2016-04-01' AND '2016-08-31'
THEN 1
ELSE 0
END AS ServiceStartedAndEnded
FROM UniqueService
WHERE UniqueService = 1
AND (ServiceActualStartDate BETWEEN '2016-04-01' AND '2016-08-31'
OR MasterEndDate BETWEEN '2016-04-01' AND '2016-08-31')
ORDER BY ClientID ASC, ScheduleOfServiceID ASC
我有一个快速的谷歌，并查看了其他一些堆栈帖子，但尚未取得任何成功。
