MySQL并集和和二表

我需要一个显示当天记录和显示每列总和的解决方案，到目前为止，我有一个查询来显示工会记录，如：

SELECT 
    datetime, 
    remarks, 
    void, 
    invoice, 
    reload, 
    redeem 
FROM
    (
      SELECT datetime, remarks, '' void, '' invoice, points_intake reload, '' redeem, 1 ord
      FROM bpp_intake_logs
      WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13'
      UNION ALL

      SELECT datetime, remarks, void, invoice, '', points_consume, 2
      FROM bpp_consume_logs
      WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13' 
    ) q
ORDER BY datetime DESC, ord 

结果表如下所示：

datetime            | remarks                        | void | invoice  | reload | redeem |
2017-06-13 15:53:31 | Point restored - void XY203460 |      |          | 10     |        |
2017-06-13 15:37:27 | reload / top-up credit         |      |          | 10     |        |
2017-06-13 15:35:56 | redeem from VIP card           |  1   | XY203460 |        | 10     |
2017-06-13 15:16:03 | redeem from VIP card           |      | XY203456 |        | 5      |

现在，我想在其所属列的底部添加一个单元格，对每个

reload

和

receive

进行求和，如下所示：

datetime            | remarks                        | void | invoice  | reload | redeem |
2017-06-13 15:53:31 | Point restored - void XY203460 |      |          | 10     |        |
2017-06-13 15:37:27 | reload / top-up credit         |      |          | 10     |        |
2017-06-13 15:35:56 | redeem from VIP card           |  1   | XY203460 |        | 10     |
2017-06-13 15:16:03 | redeem from VIP card           |      | XY203456 |        | 5      |
                                                                       | 20     | 15     |

如图所示，总和20和15分配在底部单元格中

用这种方法可以得到结果吗？

也许这就是你想要的

SELECT 
datetime, 
remarks, 
void, 
invoice, 
SUM(reload), 
SUM(redeem) 
FROM
(
  SELECT datetime, remarks, '' void, '' invoice, points_intake reload, '' redeem, 1 ord
  FROM bpp_intake_logs
  WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13'
  UNION ALL

  SELECT datetime, remarks, void, invoice, '', points_consume, 2
  FROM bpp_consume_logs
  WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13' 
) q
GROUP BY datetime desc, remarks asc, void asc, invoice asc with rollup

ORDER BY datetime DESC, ord

也许这就是你要找的

SELECT 
datetime, 
remarks, 
void, 
invoice, 
SUM(reload), 
SUM(redeem) 
FROM
(
  SELECT datetime, remarks, '' void, '' invoice, points_intake reload, '' redeem, 1 ord
  FROM bpp_intake_logs
  WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13'
  UNION ALL

  SELECT datetime, remarks, void, invoice, '', points_consume, 2
  FROM bpp_consume_logs
  WHERE outlet = 'KUL' AND DATE(datetime) = '2017-06-13' 
) q
GROUP BY datetime desc, remarks asc, void asc, invoice asc with rollup

ORDER BY datetime DESC, ord

您不能在一个查询中完成此操作。但您可以使用PHPY之类的编程语言计算重新加载和赎回的总价值。您不能在一个查询中完成这项工作。但您可以使用诸如PHP之类的编程语言计算重新加载和赎回的总值。有关了解汇总，请参阅：：：有关了解汇总，请参阅：：：
