Question

我创建了两个SQL表的示例。第一个需要简单的乘法来产生最终的＆＃34; Revenue＆＃34;而第二个表直接将这个值存储为＆＃34; Bonus＆＃34;。我希望能够做的是创建一个PHP页面，它允许我选择任何员工，并让它生成一个HTML表格（就像我的代码段中的第3个表格）。

我不确定我是否可以＆＃34;加入＆＃34;这两个表以某种方式在SQL查询中。我可以在每个表上运行两个单独的查询，两个生成两个单独的数组，但我不知道如何按日期顺序对表进行排序。

每月数据（sql表）

Month    Employee    Net Sales    Com%
Oct      Tim         275,500      .05
Oct      Sara        219,200      .06
Nov      Tim         391,500      .055
Nov      Sara        359,800      .06
Nov      Sara        116,100      .10
Nov      Alex        217,100      .04

BONUS DATA（sql table）：

Month   Employee    Bonus
Oct     Tim         500
Oct     Sara        800
Nov     Tim         600
Nov     Sara        950
Nov     Alex        450

您需要分别从两个表中提取数据，然后将它们联合起来。下面的SQL将为您提取数据，之后计算最终总数应该是striaghtforward。

SELECT
    Month,
    [Total Rev],
    Source
FROM
    (
    SELECT
        Employee,
        Month,
        SUM([Net Sales] * [Com%]) AS [Total Rev],
        'from sales' AS Source
    FROM
        [MONTHLY DATA]
    GROUP BY
        Employee,
        Month
    UNION
    SELECT
        Employee,
        Month,
        SUM(Bonus) AS [Total Rev],
        'bonus'
    FROM
        [BONUS DATA]
    GROUP BY
        Employee,
        Month
    ) AS tbl1
WHERE
    Employee='Sara'
ORDER BY
    Month,
    Source DESC
