html - 使用 MySQL 生成自定义报告

Question

我正在设计一个需要生成报告的网站。该报告必须生成详细交易和按交易完成天数分组的总交易。数据表格格式如下所示。

 _______________________________________

    |Name | Check in Date | Chec out Date | 
    ---------------------------------------
    |     |              |                |
    |     |              |                |
-------------------------------------------

我希望报告采用下表所示的格式。

    _______________________________________

    |Name | Check in Date | Chec out Date | 
    ---------------------------------------
    |     |              |                |
    |     |              |                |
    _______________________________________

   | Total  for Day 1  |                  |
   ---------------------------------------   
    |     |              |                |
    |     |              |                |
    _______________________________________
   | Total  for Day 2  |                  |
   ---------------------------------------

当我运行下面的sql查询时

SELECT check_in_time , chec_out_time , COUNT(check_in_time) FROM 
table_name GROUP BY check_in_time ORDER BY check_in_time DESC

然后我得到以下结果。

        _______________________________________________________________
   
        |Name | Check in Date | Chec out Date | COUNT(check in time)   |
        --------------------------------------------------------------
        |     |              |                |
        |     |              |                |    2                   |
        ________________________________________________________________

        |     |              |                |
        |     |              |                |       5                 |
        ________________________________________________________________

        |     |              |                |
        |     |              |                |            3          |
        ________________________________________________________________

      

我实际上希望每笔交易都显示在各自的行中，而一天的总交易则显示在新行中。

Answer 1

我使用 mysql 关键字 ROLLUP 来获得所需的结果。下面是sql脚本。

SELECT check_in_time , chec_out_time , COUNT(check_in_time) FROM 
table_name GROUP BY check_in_time DESC , id WITH ROLLUP;
