SQL Server 2008的一點過濾器/分組幫助

我從4個不同的表中獲取這些數據。我想要的信息正在返回，但是它的重複取決於項目已經通過的WorkCenterID的數量。我希望它只返回最大的工作中心ID。SQL Server 2008的一點過濾器/分組幫助

下面是代碼：

SELECT  PLT.PLT_ItemID 
     , SUM(PLD.PLD_IssueQty) AS Issued 
     , WKO.WKO_WorkOrderID 
     , WKO.WKO_RequiredQty 
     , WKO.WKO_CompleteQty 
     , WKO.WKO_RequiredQty - WKO.WKO_CompleteQty AS openbalance 
     , PLT.PLT_QtyPerAssy 
     , (WKO.WKO_CompleteQty * PLT.PLT_QtyPerAssy - SUM(PLD.PLD_IssueQty)) * - 1 AS WIP 
     , WKO.WKO_ItemID 
     , WKO.WKO_StatusCode 
     , WKO.WKO_LastWorkDate 
     , WOO.WOO_WorkCenterID 
FROM  PLT 
       INNER JOIN PLD ON PLT.PLT_RecordID = PLD.PLD_PLT_RecordID 
       INNER JOIN WKO ON PLT.PLT_WorkOrderID = WKO.WKO_WorkOrderID 
       LEFT OUTER JOIN WOO ON PLT.PLT_WorkOrderID = WOO.WOO_WorkOrderID 
WHERE  (WKO.WKO_StatusCode = N'Released') 
     AND (PLT.PLT_ItemID = '1700-0535501-01') 
GROUP BY PLT.PLT_ItemID 
     , WKO.WKO_WorkOrderID 
     , WKO.WKO_RequiredQty 
     , WKO.WKO_CompleteQty 
     , PLT.PLT_QtyPerAssy 
     , WKO.WKO_ItemID 
     , WKO.WKO_LastWorkDate 
     , WOO.WOO_WorkCenterID 
     , WKO.WKO_StatusCode 
HAVING  (SUM(PLD.PLD_IssueQty) = WKO.WKO_RequiredQty * PLT.PLT_QtyPerAssy) 
ORDER BY WKO.WKO_WorkOrderID

下面是結果：

PLT_ItemID Issued WKO_WorkOrderID WKO_RequiredQty WKO_CompleteQty openbalance PLT_QtyPerAssy WIP WKO_ItemID WKO_StatusCode WKO_LastWorkDate WOO_WorkCenterID

您可以使用ROW_NUMBER（）函數。就像這樣：

WITH a AS ( 
    SELECT ROW_NUMBER() OVER(PARTITON BY WKO.WKO_WorkOrderID ORDER BY WKO.WKO_WorkOrderID) AS RowNo  
     , PLT.PLT_ItemID 
     , SUM(PLD.PLD_IssueQty) AS Issued 
     , WKO.WKO_WorkOrderID 
     , WKO.WKO_RequiredQty 
     , WKO.WKO_CompleteQty 
     , WKO.WKO_RequiredQty - WKO.WKO_CompleteQty AS openbalance 
     , PLT.PLT_QtyPerAssy 
     , (WKO.WKO_CompleteQty * PLT.PLT_QtyPerAssy - SUM(PLD.PLD_IssueQty)) * - 1 AS WIP 
     , WKO.WKO_ItemID 
     , WKO.WKO_StatusCode 
     , WKO.WKO_LastWorkDate 
     , WOO.WOO_WorkCenterID 
FROM  PLT 
       INNER JOIN PLD ON PLT.PLT_RecordID = PLD.PLD_PLT_RecordID 
       INNER JOIN WKO ON PLT.PLT_WorkOrderID = WKO.WKO_WorkOrderID 
       LEFT OUTER JOIN WOO ON PLT.PLT_WorkOrderID = WOO.WOO_WorkOrderID 
WHERE  (WKO.WKO_StatusCode = N'Released') 
     AND (PLT.PLT_ItemID = '1700-0535501-01') 
GROUP BY PLT.PLT_ItemID 
     , WKO.WKO_WorkOrderID 
     , WKO.WKO_RequiredQty 
     , WKO.WKO_CompleteQty 
     , PLT.PLT_QtyPerAssy 
     , WKO.WKO_ItemID 
     , WKO.WKO_LastWorkDate 
     , WOO.WOO_WorkCenterID 
     , WKO.WKO_StatusCode 
HAVING  (SUM(PLD.PLD_IssueQty) = WKO.WKO_RequiredQty * PLT.PLT_QtyPerAssy) 
) 

SELECT * FROM a WHERE a.RowNo = 1

選擇只有你實際回報當然領域... :)

所以我認爲這可能會有所幫助，我想要完成的是根據最大的工作中心ID爲每個零件號取一個不同的工作單號所以基本上我希望看到3個總記錄返回。每個工作訂單最大的WorkcenterID – jballard81

我不確定我是否理解你的意思，但是我更新了查詢以對WorkOrderId上的ROW_NUMBER（）進行分區並按WorkCenterID對其進行排序。這樣你應該能夠得到想要的結果（當然，我明白你想要什麼......）當SELECT * WHERE RowNo = 1 – tillmannen
