我有一个如下查询,运行大约需要 10 分钟,我必须对其进行优化。我尝试了我的一点,但我无法提高它的性能。非常感谢任何帮助

您可以做的一个非常快速的测试是修改它以使用临时表。这可能会或可能不会产生太大影响,但这是一个可以尝试的快速测试。

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,如果没有架构和索引的更多详细信息,很难调整此 SQL。如果您可以运行查询并检查执行计划,您将能够看到延迟的来源。
