MS SQL汇总百分比列

Question

我使用汇总来汇总包含字段company，sales，cost和margin的表格。这给了我汇总的列，但我需要显示保证金的总结百分比，作为每个公司摘要的销售百分比。

这是我目前的陈述：

SELECT coalesce(CAST(Company AS VARCHAR(30)), 'Grand Total:') AS Company,
       SUM(Sales)                                             AS 'TOTSALES',
       SUM(CostVal)                                           AS 'TOTCOST',
       SUM(MarginVal)                                         AS 'TOTMAR'
FROM   DailySalesSum
GROUP  BY Company WITH ROLLUP;  

Answer 1

SELECT coalesce(CAST(Company AS VARCHAR(30)), 'Grand Total:') AS Company,
       SUM(Sales)                                             AS 'TOTSALES',
       SUM(CostVal)                                           AS 'TOTCOST',
       SUM(MarginVal)                                         AS 'TOTMAR',
       100.0 * SUM(MarginVal) / SUM(Sales)                    AS 'MARGINPERCENT'
FROM   DailySalesSum
GROUP  BY Company WITH ROLLUP;

如同马丁所说，并将其作为额外字段添加到您的陈述中，如上所示。
