STATEMENT ERROR（子查詢返回的值超過1）

Question

這是我第一個問題。我剛剛接管了以前的IT人員的SQL報告，我正在努力處理下面的查詢。它突然停止工作兩天前，現在顯示：

報告處理過程中發生錯誤。 （rsProcessingAborted） 數據集「DataSet1」的查詢執行失敗。 （rsErrorExecutingCommand） 子查詢返回多個值。當子查詢遵循=，！=，<，< =，>，> =或當子查詢用作表達式時，這是不允許的。該語句已終止。

它停止在第49行：

and (select t.[status] from [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t left join [ksimakeprod01].[imake].dbo.WORKORDER wa on t.WorkOrderKey=wa.WORKORDERKEY where wa.workorderno=wh.WorkOrderNo)<>7 

我從我試圖更新多行數據的列錯誤理解......但是這查詢之前的工作......我該如何解決它？

全面查詢：。

Answer 1

和（選擇T [狀態]從[ksimakeprod01] [imake的] .dbo.iSchWOScheduleLine牛逼左加入[ksimakeprod01] [imake的] .dbo.WORKORDER。 WA上t.WorkOrderKey = wa.WORKORDERKEY其中wa.workorderno = wh.WorkOrderNo）<> 7

的問題是，該查詢返回現在多行。如果你自己運行查詢，這將是顯而易見的。解決這個問題最簡單的方法是確保只有1行通過使用TOP子句返回，就像這樣。

and (select TOP 1 t.[status] from [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t left join [ksimakeprod01].[imake].dbo.WORKORDER wa on t.WorkOrderKey=wa.WORKORDERKEY where wa.workorderno=wh.WorkOrderNo)<>7 

您應該意識到這是一個「錯誤」修復，因爲它可能會導致您的整個查詢返回錯誤的數據。可以這麼想......你檢查狀態列是否是7.但是，由於查詢返回多行，一個狀態值可能是7，而另一個可能是7以外的值。因爲你是現在使用頂部子句，頂部行可以是7，或者頂部行可以是其他值。

我討厭這麼說，但解決這個問題的最好方法是完全重寫。這是確保您的查詢做得正確的唯一方法。

Answer 2

如果它完成於：

(select 
    t.[status] 
from 
    [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t 
left join 
    [ksimakeprod01].[imake].dbo.WORKORDER wa 
on 
    t.WorkOrderKey=wa.WORKORDERKEY 
where 
    wa.workorderno=wh.WorkOrderNo)<>7 

那麼問題是，這種子查詢返回多個記錄，所以你不能把它比作一個值。您可以強制它僅使用TOP 1返回一個值，但它取決於上下文是否合適。如果你確實使用了這種方法，那麼你基本上會忽略來自該查詢的所有其他值，並且選擇出現的第一個值可能沒有意義！

(select 
    TOP 1 t.[status] 
from 
    [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t 
left join 
    [ksimakeprod01].[imake].dbo.WORKORDER wa 
on 
    t.WorkOrderKey=wa.WORKORDERKEY 
where 
    wa.workorderno=wh.WorkOrderNo)<>7
