Question

我正在尝试仅显示符合位置条件的记录。困境是位置存储在逗号分隔列表中，这使得它变得更难。

这是代码

DECLARE @sessionStart DATETIME, 
@sessionEnd DATETIME, 
@instructorKey INT, 
@locationKey INT 

SET @instructorKey = 1
SET @sessionStart = '2015-03-01'
SET @sessionEnd = '2015-04-05'
SET @locationKey = null 
SELECT SU.sessionUnitKey, s.locationKey,s.locationKeyList,SU.sessionStart, SU.sessionEnd
FROM sessionUnit SU WITH (NOLOCK) 
INNER JOIN session S WITH (NOLOCK) ON SU.sessionKey = S.sessionKey 
left JOIN location L WITH (NOLOCK) ON (S.locationKey = L.locationKey ) 
INNER JOIN product P WITH (NOLOCK) ON S.productKey = P.productKey 
INNER JOIN users U WITH (NOLOCK) ON SU.instructorKey = U.userKey 
INNER JOIN lkup_productType PT WITH (NOLOCK) ON P.productTypeKey = PT.productTypeKey 

CROSS APPLY DelimitedSplit8K('10,260,34,102,15', ',')  ds 
inner join Location L2 on L2.locationKey = ds.Item

WHERE 1=1 
AND EXISTS ( SELECT 1 from ins_car_loc ICL WITH (NOLOCK) WHERE ICL.RptingInskey = SU.instructorKey and ICL.instructorKey = @instructorKey and ICL.endDt is NULL ) 


AND (@sessionStart IS NULL OR SU.sessionStart >= @sessionStart) AND (@sessionEnd IS NULL OR SU.sessionStart <= @sessionEnd) 
ORDER BY SU.sessionUnitKey

，这是示例输出

sessionUnitKey  locationKey locationKeyList sessionStart    sessionEnd

我需要的是locationKeyList带有给定条件的记录，locationKey也包含该列表

Answer 1

难道你不必像那样交叉申请吗？

CROSS APPLY
(
SELECT match
FROM DelimitedSplit8K('10,260,34,102,15', ',')
) as t(country)

SQL CROSS应用逗号分隔列表
