Question

我正在尝试基于WorkCentres加入2个表。在一个表中，该字段称为LWorkCentre，在另一个表中称为WorkCentre。

我已经完成了一个Full Outer Join来加入这两个表。然后我想根据加班工作中心返回加班时间。因此，超时WorkCentre适用的地方则返回运行时间，否则返回0.

这是我编写视图的方式，但它没有返回任何值。请帮助我不知道我哪里出错了。

SELECT DISTINCT 
dbo.PrjJobHierDet.JobEstimate AS CONTRACT,
dbo.PrjContMaster.ContractDesc1 AS CONTRACT_NAME,
dbo.WipJobPost.TrnDate AS DATE,
dbo.WipJobPost.LWorkCentre AS WORKCENTRE,
dbo.WipJobPost.LWorkCentreDesc AS WORKCENTRE_DESC,
dbo.WipJobPost.Hierarchy1 AS SECTION,
dbo.WipJobPost.Hierarchy2 AS HIER,
dbo.WipJobPost.LEmployee AS EMPLOYEE_ID,
dbo.BomEmployee.Name AS EMPLOYEE_NAME,
dbo.WipJobPost.LRunTimeHours AS HOURS_WORKED,
dbo.BomEmployee.MtdActProdHours AS PRODUCTION_HOURS,
dbo.BomEmployee.MtdNonProdHours AS STANDING_TIME_HOURS, 
dbo.BomEmployee.StdHrsPerMonth AS BUDGETED_HOURS,
CASE
   WHEN LWorkCentre = 'CCOTAR' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTAR' THEN 0
   WHEN LWorkCentre = 'CCOTWI' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTWI' THEN 0
   WHEN LWorkCentre = 'CCOTPM' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTPM' THEN 0
   WHEN LWorkCentre = 'CCOTLA' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTLA' THEN 0
   WHEN LWorkCentre = 'CCOTSA' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTSA' THEN 0
   WHEN LWorkCentre = 'CCOTSU' THEN LRunTimeHours
   WHEN LWorkCentre != 'CCOTSU' THEN 0
   WHEN LWorkCentre = 'ELOTAD' THEN LRunTimeHours
   WHEN LWorkCentre != 'ELOTAD' THEN 0
   WHEN LWorkCentre = 'ELOTCA' THEN LRunTimeHours
   WHEN LWorkCentre != 'ELOTCA' THEN 0
   WHEN LWorkCentre = 'ELOTDE' THEN LRunTimeHours
   WHEN LWorkCentre != 'ELOTDE' THEN 0
   WHEN LWorkCentre = 'MAOTFA' THEN LRunTimeHours
   WHEN LWorkCentre != 'MAOTFA' THEN 0
END AS Overtime

根据查询，只有在内部联接中没有可加入的数据才有意义。

这两个表是否会在同一个字段上加入？

 INNER JOIN  dbo.WipJobPost
    ON dbo.PrjJobHierDet.JobEstimate = dbo.WipJobPost.Job
 INNER JOIN dbo.PrjContMaster
    ON dbo.PrjContMaster.Contract = dbo.WipJobPost.Job

如果不知道您的数据的结构如何，请尝试将内部联接切换为LEFT OUTER JOIN以确定其未正确加入的原因

从2个表中返回数据并过滤掉信息
