在CASE语句和GROUP BY子句中计算保证金

时间：2015-11-06 06:07:28

标签： sql group-by case aggregate margin

我认为我在选择按分组语句聚合列的过程中遇到了错误。

我正在计算保证金百分比并使用像这样的案例陈述分组成几个月：

SUM(CASE WHEN MONTH(DateProcessed) = 1 AND Revenus <> 0 THEN (Revenue - Cost) / Revenue ELSE 0 END AS [January]

所以我的等式最终为：SUM( (Revenue - Cost) / Revenue )

多个交易在几个月内给出了错误的价值

我确信我的等式必须是：SUM(Revenue - Cost) / SUM(Revenue)

但我不能像那样格式化我的案例陈述。你会如何计算出这种方程？

谢谢，

您可以使用子查询来获取每月当前CASE语句中的收入总和（1月如下所示）。

SELECT SUM(CASE WHEN MONTH(t1.DateProcessed) = 1 AND t1.Revenue <> 0
                THEN (t1.Revenue - t1.Cost)
                ELSE 0 END) / 
       (SELECT SUM(t2.revenue) FROM table t2
        WHERE MONTH(t2.DateProcessed) = 1) AS [January]
