Question

我正在尝试编写一份报告，为销售数据生成4组：每日，每月，每季度和每年。我遇到的问题是，如果没有每日活动，它将不会每月，每季度或每年生成。如何获得没有数据生成0的日子并仍然计算其他三组？这是我正在尝试使用的代码（它还没有将年份作为一个组包含在内）：

WITH Summary AS
(SELECT
    1 as GRP,
    'DAILY' as Label,
    O.SnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.DollarsBilled) = 0 THEN 0 ELSE SUM(O.DollarsBilled) END, 
    BilledMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE SUM(O.MsfBilled) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE (SUM(O.DollarsBilled)/SUM(O.MsfBilled)) END,
    BilledContribution = CASE WHEN SUM(O.Contribution) = 0 THEN 0 ELSE SUM(O.Contribution) END,
    BilledProfit = CASE WHEN SUM(O.Profit) = 0 THEN 0 ELSE SUM(O.Profit) END
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey = 20161230 and O.SalesRepKey = 167
GROUP BY
    O.SnapshotDateKey

UNION

SELECT
    2 as GRP,
    'MTD' as Label,
    O.SnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.MTDDollarsBilled) = 0 THEN 0 ELSE (SUM(O.MTDDollarsBilled)) END, 
    BILLEDMSF = CASE WHEN SUM(O.MTDMsfBilled) = 0 THEN 0 ELSE (SUM(O.MTDMsfBilled)) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.MTDMsfBilled) = 0 THEN 0 ELSE (SUM(O.MTDDollarsBilled)/SUM(O.MTDMsfBilled)) END,
    SUM(O.MTDContribution) as BilledContribution,
    SUM(O.MTDProfit) as BilledProfit
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey = 20161230 and O.SalesRepKey = 167
GROUP BY
    O.SnapshotDateKey

UNION

SELECT
    3 as GRP,
    'QTD' as Label,
    O.SnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.QTDDollarsBilled) = 0 THEN 0 ELSE (SUM(O.QTDDollarsBilled)) END, 
    BILLEDMSF = CASE WHEN SUM(O.QTDMsfBilled) = 0 THEN 0 ELSE (SUM(O.QTDMsfBilled)) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.QTDMsfBilled) = 0 THEN 0 ELSE (SUM(O.QTDDollarsBilled)/SUM(O.QTDMsfBilled)) END,
    SUM(O.QTDContribution) as BilledContribution,
    SUM(O.QTDProfit) as BilledProfit
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey = 20161230 and O.SalesRepKey = 167
GROUP BY
    O.SnapshotDateKey
) 

SELECT * FROM Summary
UNION ALL SELECT NULL, 0,0,0,0,0  WHERE NOT EXISTS (SELECT * FROM Summary)

谢谢！

考虑更改WHERE子句，因为union查询的所有部分都指向可能/可能不包含数据的精确单个日期。此外，重复所有部分中的每日聚合，因为更新的WHERE条件将扩展行数。无需维护MTD，QTD或YTD列。此外，不需要GROUP BY，因为所有列都可以与 GRP 和 Label 常量进行聚合。

由于SnapshotDateKey似乎将日期捕获为数字，因此只需过滤非日常时段的适当范围即可。以下是CTE声明的更新：

WITH Summary AS

(SELECT
    1 as GRP,
    'DAILY' as Label,
    MAX(O.SnapshotDateKey) AS MaxSnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.DollarsBilled) = 0 THEN 0 ELSE SUM(O.DollarsBilled) END, 
    BilledMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE SUM(O.MsfBilled) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE (SUM(O.DollarsBilled)/SUM(O.MsfBilled)) END,
    BilledContribution = CASE WHEN SUM(O.Contribution) = 0 THEN 0 ELSE SUM(O.Contribution) END,
    BilledProfit = CASE WHEN SUM(O.Profit) = 0 THEN 0 ELSE SUM(O.Profit) END
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey = 20161230 and O.SalesRepKey = 167

UNION

SELECT
    2 as GRP,
    'MTD' as Label,
    MAX(O.SnapshotDateKey) AS MaxSnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.DollarsBilled) = 0 THEN 0 ELSE SUM(O.DollarsBilled) END, 
    BilledMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE SUM(O.MsfBilled) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE (SUM(O.DollarsBilled)/SUM(O.MsfBilled)) END,
    BilledContribution = CASE WHEN SUM(O.Contribution) = 0 THEN 0 ELSE SUM(O.Contribution) END,
    BilledProfit = CASE WHEN SUM(O.Profit) = 0 THEN 0 ELSE SUM(O.Profit) END
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey BETWEEN 20161201 AND 20161230 and O.SalesRepKey = 167

UNION

SELECT
    3 as GRP,
    'QTD' as Label,
    MAX(O.SnapshotDateKey) AS MaxSnapshotDateKey,
    BilledDollars = CASE WHEN SUM(O.DollarsBilled) = 0 THEN 0 ELSE SUM(O.DollarsBilled) END, 
    BilledMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE SUM(O.MsfBilled) END, 
    BookedDollarsPerMSF = CASE WHEN SUM(O.MsfBilled) = 0 THEN 0 ELSE (SUM(O.DollarsBilled)/SUM(O.MsfBilled)) END,
    BilledContribution = CASE WHEN SUM(O.Contribution) = 0 THEN 0 ELSE SUM(O.Contribution) END,
    BilledProfit = CASE WHEN SUM(O.Profit) = 0 THEN 0 ELSE SUM(O.Profit) END
FROM
    FactInvoiceSummary O
WHERE
    O.SnapshotDateKey BETWEEN 20161001 AND 20161230 and O.SalesRepKey = 167
)

除此之外 - 理想情况下，您使用日期时间字段来维护日期/时间部分以提取日/周/月/季/年指标。同样如上所示，仅汇总一个的DollarsBilled，MsfBilled，Contribution，Profit列，而不计算MTD，QTD，YTD的计算集。

按每日，每月，每季度和每周生成销售数据年度团体
