SQL添加新列，在其他列中划分数字

Question

我一直试图操作此代码一段时间但无济于事 - 感谢任何帮助：

我有一个列表框，其中有两列带有数字（数据来自查询。在列表框中，我想添加第三列，将第二列除以第一列。

我的代码：

    SELECT 
     Q_Manager_CHS_Total.tbl_CEAR_Name.CEAR_Team
     T1.Q_Manager_Backlog_Total.Backlogs
     Q_Manager_CHS_Total.CHS_Total

      (T1.Q_Manager_Backlog_Total.Backlogs/Q_Manager_CHS_Total.CHS_Total) AS AverageNumber
FROM 
     Q_Manager_CHS_Total
INNER JOIN (SELECT Q_Manager_Backlog_Total.Backlogs, tbl_CEAR_Name.CEAR_Team 
INNER JOIN tbl_CEAR_Name ON Q_Manager_Backlog_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team) AS T1 
ON Q_Manager_CHS_Total.CEAR_Team = T1.CEAR_Team
ORDER BY T1.Q_Manager_Backlog_Total.Backlogs DESC;

任何帮助我们努力工作的人都会受到赞赏。

更新：下面的SQL工作并显示两列，它添加了我似乎无法做的第三列。

    SELECT Q_Manager_CHS_Total.tbl_CEAR_Name.CEAR_Team, T1.Q_Manager_Backlog_Total.Backlogs, Q_Manager_CHS_Total.CHS_Total
FROM Q_Manager_CHS_Total INNER JOIN (SELECT Q_Manager_Backlog_Total.Backlogs, tbl_CEAR_Name.CEAR_Team FROM Q_Manager_Backlog_Total INNER JOIN tbl_CEAR_Name ON Q_Manager_Backlog_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team) AS T1 ON Q_Manager_CHS_Total.CEAR_Team = T1.CEAR_Team
ORDER BY T1.Q_Manager_Backlog_Total.Backlogs DESC;

SELECT Q_Manager_CHS_Total.tbl_CEAR_Name.CEAR_Team, T1.Q_Manager_Backlog_Total.Backlogs, Q_Manager_CHS_Total.CHS_Total, T1.Q_Manager_Backlog_Total.Backlogs/Q_Manager_CHS_Total.CHS_Total AS percentage
FROM Q_Manager_CHS_Total INNER JOIN (SELECT Q_Manager_Backlog_Total.Backlogs, tbl_CEAR_Name.CEAR_Team FROM Q_Manager_Backlog_Total INNER JOIN tbl_CEAR_Name ON Q_Manager_Backlog_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team)  AS T1 ON Q_Manager_CHS_Total.CEAR_Team = T1.CEAR_Team
ORDER BY T1.Q_Manager_Backlog_Total.Backlogs DESC;
