如何遍歷ID列表

我在select語句中獲取了id的列表。如何通過每個ID循環並打印下面如何遍歷ID列表

DECLARE @InventoryID INT 
Select @InventoryID = I.InventoryID 
From G2owner.LoadSlip L (nolock) 
    Inner Join G2owner.LoadSlipReleaseOrderMapping LM (nolock) on L.LoadSlipID = LM.LoadSlipID 
    Inner Join G2owner.LoadSlipDetail LSD (nolock) on LM.LoadSlipReleaseOrdermappingID = LSD.LoadSlipReleaseOrdermappingID 
    Inner Join G2owner.Inventory I (nolock) on LSD.InventoryID = I.InventoryID 
Where LM.ReleaseOrderID = 7156 and L.LoadSlipID = 3014 
     and L.TerminalID = 3 and I.InventoryEndDate IS NULL and I.TotalNetWeight = 0.0000000 

PRINT @InventoryID

是什麼讓你覺得你需要一個循環？只需使用'Select I.InventoryID From ...'。 –

我需要循環，因爲我需要在其他存儲過程中的多個位置使用每個invetoryID – user1030181

即使將ID列表轉儲到臨時表，您也應儘量嘗試儘量使用基於集合的邏輯。但是，如果你堅持要使用循環，你必須[使用遊標]（http://stackoverflow.com/questions/11856518/sql-server-2008-request-example-on-creating-a -cursor-to-loop-through-records）來執行你所描述的內容。 –

避免遊標或行操作，如果你可以因爲它阻礙了性能，它使用循環的任何行，但如果你有：

DECLARE @InventoryID INT 

DECLARE myCursor CURSOR FOR 
SELECT I.InventoryID 
From G2owner.LoadSlip L with(nolock) 
    Inner Join G2owner.LoadSlipReleaseOrderMapping LM with(nolock) on L.LoadSlipID = LM.LoadSlipID 
    Inner Join G2owner.LoadSlipDetail LSD with(nolock) on LM.LoadSlipReleaseOrdermappingID = LSD.LoadSlipReleaseOrdermappingID 
    Inner Join G2owner.Inventory I with(nolock) on LSD.InventoryID = I.InventoryID 
Where LM.ReleaseOrderID = 7156 and L.LoadSlipID = 3014 
    and L.TerminalID = 3 and I.InventoryEndDate IS NULL and I.TotalNetWeight = 0.0000000 

OPEN myCursor 
FETCH NEXT FROM myCursor INTO @InventoryID 

WHILE @@FETCH_STATUS = 0 
BEGIN 

    PRINT (@InventoryID); 
    FETCH NEXT FROM myCursor INTO @InventoryID 
END 
CLOSE myCursor 
DEALLOCATE myCursor

而且WITH(nolock)會導致髒讀！

NOLOCK不僅僅是髒讀。老實說，與使用該提示時可能發生的一些事情相比，髒讀取是微不足道的。請參閱上面評論中的鏈接@marc_s，以獲取有關提示帶給表格的所有令人討厭的內容的更多詳細信息。 –
