SQL 将来自两个不同日期范围的数据合并到一个结果集中

Question

使用 SqlServer 2008，我有一个临时表 (#tmpAllSales)，它记录了一年的所有销售额。我想创建一个 SELECT 语句，其中包含当年的销售额以及上一季度的销售额。

类似这样的事情（@StartDate 和 @EndDate 被定义为一个季度的开始/结束）：

--QTD Sales By Company
SELECT
    Company,
    SUM(Call) as TotalCallsQTD,
    SUM(Call) - SUM(SoldCall) as FreeCallsQTD,
    SUM(SalableCall) as SalesRelatedCallsQTD,
    SUM(SoldCall) as SoldCallsQTD
FROM
    #tmpAllSales
WHERE
    CalledOn between @StartDate and @EndDate
GROUP BY
    Company

--COMBINED WITH BASED ON Company

--YTD Sales By Company
SELECT
    Company,
    SUM(Call) as TotalCallsYTD,
    SUM(Call) - SUM(SoldCall) as FreeCallsYTD,
    SUM(SalableCall) as SalesRelatedCallsYTD,
    SUM(SoldCall) as SoldCallsYTD
FROM
    #tmpAllSales
GROUP BY
    Company
ORDER BY
    Company

每个单独的查询都会给出我想要的结果，但我不知道如何组合成一个结果集。

我在原始帖子中没有明确表示我希望在每家公司的一行中获得所有结果。我在 Excel 宏中使用它，所以如果所有信息都在一行上，那就太好了。

Answer 1

SELECT
    Period = 'QTD',
    Company,
    SUM(Call) as TotalCallsQTD,
    SUM(Call) - SUM(SoldCall) as FreeCallsQTD,
    SUM(SalableCall) as SalesRelatedCallsQTD,
    SUM(SoldCall) as SoldCallsQTD
FROM
    #tmpAllSales
WHERE
    CalledOn between @StartDate and @EndDate
GROUP BY
    Company
UNION ALL
SELECT
    Period = 'YTD',
    Company,
    SUM(Call) as TotalCallsYTD,
    SUM(Call) - SUM(SoldCall) as FreeCallsYTD,
    SUM(SalableCall) as SalesRelatedCallsYTD,
    SUM(SoldCall) as SoldCallsYTD
FROM
    #tmpAllSales
GROUP BY
    Company
ORDER BY
    Period, Company;

如果您希望它们作为每个公司的单行，那么：

;WITH q AS
(
    SELECT
        Company,
        SUM(Call) as TotalCallsQTD,
        SUM(Call) - SUM(SoldCall) as FreeCallsQTD,
        SUM(SalableCall) as SalesRelatedCallsQTD,
        SUM(SoldCall) as SoldCallsQTD
    FROM
        #tmpAllSales
    WHERE
        CalledOn between @StartDate and @EndDate
    GROUP BY
        Company
), y AS 
(
    SELECT
        Company,
        SUM(Call) as TotalCallsYTD,
        SUM(Call) - SUM(SoldCall) as FreeCallsYTD,
        SUM(SalableCall) as SalesRelatedCallsYTD,
        SUM(SoldCall) as SoldCallsYTD
    FROM
        #tmpAllSales
    GROUP BY
        Company
)
SELECT q.Company, qTotalCallsYTD = q.TotalCallsYTD, etc...,
    yTotalCallsYTD = y.TotalCallsYTD, etc...
FROM q INNER JOIN y
ON q.Company = y.Company
ORDER BY q.Company;
