從2個表中返回數據並過濾出信息

Question

我想根據WorkCentres加入2個表。在一個表中，該字段稱爲LWorkCentre，在另一個表中稱爲WorkCentre。

我已經完成了一個Full Outer Join來加入這兩個表。然後我想根據加班工作中心返回加班時間。因此，在加班WorkCentre適用的情況下，返回運行時間，否則返回0.

這就是我如何編寫視圖，但是它沒有返回任何值。 請幫助我不知道我要去哪裏錯了。

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

基礎上查詢時，它纔有意義，沒有任何數據在你的內連接可連接。

這兩個表加入同一個字段，應該是什麼？

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

不知道你的數據是怎麼回事結構，嘗試切換您的內部連接到LEFT OUTER JOIN s到弄清楚它爲什麼不加入適當
