sql - 如何将 3 个查询合并为一个

Question

我有 3 个查询，最终可以获取每日财务信息。我想做的是将我需要的列合并为 1 个输入。我尝试做派生表，但它非常草率并且不起作用。有人对如何将这 3 个结合起来在 1 行上提供输出有任何建议吗？

这是我的疑问:

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

第二个查询:

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'))

第三个查询:

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

最简单的方法是这样的

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。

我认为没有办法在没有笛卡尔积的情况下组合 3 个不同的查询。
