Question

我有3个查询，最终可以获取每日财务信息。我想要做的是将我需要的列组合为1个输入。我尝试做派生表，但它非常草率，不起作用。有没有人有任何建议我如何将这3个组合在一起给我输出？

以下是我的疑问：

SELECT        ReportCategoryID, ReportCategoryName, PrintOrder, QTY, NetAmt, customers, Average
FROM            dbo.fRevenueSummary(@startdate, @enddate) AS fRevenueSummary_1

第二次查询：

SELECT        COUNT(*) AS count, SUM(TicketsDetails.dblTotal) AS Merch_Total
FROM            TicketsDetails INNER JOIN
                         Surcharges ON TicketsDetails.Reference_ID = Surcharges.Surcharge_ID INNER JOIN
                         SurchargesTypes ON Surcharges.lSurchargeTypeID = SurchargesTypes.lSurchargeTypeID
WHERE        (TicketsDetails.dtCreated BETWEEN @startdate AND @enddate) AND (SurchargesTypes.lSurchargeTypeID = '2') AND (TicketsDetails.bPaid = 1) AND 
                         (TicketsDetails.Detail_Type_ID = 3) AND (NOT (TicketsDetails.sDescription = N'TIP'))

第三次质询：

SELECT        SUM(dblRegLabor) AS Regular_Amount, SUM(dblOTLabor) AS OT_Amount
FROM            TimeClock
WHERE        (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '1') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '2') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '3') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '4') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '5') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '6') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '7')

Answer 1

最简单的方法就是这样

SELECT *
FROM
(
    SELECT        ReportCategoryID, ReportCategoryName, PrintOrder, QTY, NetAmt, customers, Average
    FROM            dbo.fRevenueSummary(@startdate, @enddate) AS fRevenueSummary_1
)
,
(
    SELECT        COUNT(*) AS count, SUM(TicketsDetails.dblTotal) AS Merch_Total
    FROM            TicketsDetails INNER JOIN
                         Surcharges ON TicketsDetails.Reference_ID = Surcharges.Surcharge_ID INNER JOIN
                         SurchargesTypes ON Surcharges.lSurchargeTypeID = SurchargesTypes.lSurchargeTypeID
    WHERE        (TicketsDetails.dtCreated BETWEEN @startdate AND @enddate) AND (SurchargesTypes.lSurchargeTypeID = '2') AND (TicketsDetails.bPaid = 1) AND 
                         (TicketsDetails.Detail_Type_ID = 3) AND (NOT (TicketsDetails.sDescription = N'TIP'))
)
,
(
    SELECT        SUM(dblRegLabor) AS Regular_Amount, SUM(dblOTLabor) AS OT_Amount
    FROM            TimeClock
    WHERE        (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '1') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '2') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '3') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '4') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '5') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '6') OR
                         (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = '7')
)

但如果它们之间没有关系，您将返回笛卡尔积。

我不认为有一种方法可以在没有笛卡尔积的情况下组合3个不同的查询。

Answer 2

这不是您问题的答案，但它可以简化您的想法，以便知道您的第三个查询可以大大简化：

SELECT  SUM(dblRegLabor) AS Regular_Amount, SUM(dblOTLabor) AS OT_Amount
FROM    TimeClock
WHERE   (dtTimeIn > @startdate) AND (dtTimeOut < @enddate) AND (sDept = IN('1', '2', '3', '4', '5', '6', '7'))

Answer 3

好吧，如果你想要丑陋，凌乱的解决方案，你可以在每个语句周围加上括号，然后将每个语句视为巨型JOIN中的表（类似于Marc所说的那样）。

如果你想要一个好的解决方案，你将不得不描述你实际上想要做的事情。在不知道您的数据和实际任务的情况下we can't optimize your code。
