無法提高查詢性能

我有一個查詢如下，這需要約10分鐘的運行，我必須優化。我嘗試了一下，但我無法提高它的表現。任何幫助，非常感謝無法提高查詢性能

很難幫助只是SQL。請提供更多詳細信息，如底層表結構，索引，數據量，服務器資源等。 – Raj

請嘗試sqlfiddle？會更容易爲大家:) – Bren

一個非常簡單的測試，你可以做的是修改它使用臨時表。這可能會或可能沒有太大的影響，但這是一個快速嘗試。

SELECT DISTINCT OH.intStore 
      , OH.strBarcode 
      , SA.intAreaGrp 
      , OH.strDesc 
      , OH.czBrand 
      , OH.decCost 
      , AG.strAreaName 
      , OH.fltQty 
      , OH.dtmCreatedDate 
INTO #TEMP_OX 
FROM tblOnHand AS OH 
LEFT JOIN dbo.tblStickerAreas AS SA ON (OH.intArea = SA.intAreaNo) 
LEFT JOIN dbo.tblAreaGrp AS AG ON (SA.intAreaGrp = AG.intAreaGrp) 

SELECT DT.intStore 
    , DT.strClientText 
    , SA.intAreaGrp 
    , AG.strAreaName 
    , SUM(DT.fltQty) SumQty 
    , MIN(DT.strBarCode) FirstBarCode 
INTO #TEMP_DX 
FROM dbo.tblDetail AS DT 
JOIN dbo.tblSticker AS SK ON (DT.intStore = SK.intStore 
    AND DT.intStickerNo = SK.intStickerNo 
    AND DT.dtmstickerdate = SK.dtmstickerdate 
    AND SK.strrescansw = 'N') 
LEFT JOIN dbo.tblStickerAreas AS SA ON (SK.intAreaNo = SA.intAreaNo) 
LEFT JOIN dbo.tblAreaGrp AS AG ON (SA.intAreaGrp = AG.intAreaGrp) 
--WHERE strrescansw = 'N' 
GROUP BY 
     DT.intStore 
    , DT.strClientText 
    , SA.intAreaGrp 
    , AG.strAreaName 

SELECT ISNULL(OX.intStore, DX.intStore) AS sStore 
    , OX.dtmCreatedDate 
    , ISNULL(OX.strBarcode, ISNULL(DX.strClientText, DX.FirstBarCode)) AS sBarcode 
    , ISNULL(OX.strAreaName, DX.strAreaName) AS sArea 
    , ISNULL(OX.strDesc, 'N/F') AS sDesc 
    , ISNULL(OX.czBrand, 'N/F') AS sBrand 
    , ISNULL(OX.decCost, 0) AS nCost 
    , ISNULL(DX.SumQty, 0) AS nHT_Unit 
    , ISNULL(OX.fltQty, 0) AS nOH_Unit 
    , (ISNULL(DX.SumQty, 0) * ISNULL(OX.decCost, 0)) AS nEXTCost 
    , (ISNULL(OX.fltQty, 0) * ISNULL(OX.decCost, 0)) AS nOH_EXTCost 
    , (ISNULL(DX.SumQty, 0) - ISNULL(OX.fltQty, 0)) AS nVarUnit 
    , (ISNULL(DX.SumQty, 0) - ISNULL(OX.fltQty, 0)) * ISNULL(OX.decCost, 0) AS nVarCost 
FROM #TEMP_OX 
FULL OUTER JOIN #TEMP_DX 
    ON OX.intStore = DX.intStore AND OX.strBarcode = DX.strClientText

除此之外，沒有更多架構和索引的詳細信息，很難調整此SQL。如果您可以運行查詢並檢查執行計劃，您將能夠看到延遲來自何處。
