mysql - SQL - 是否可以查找具有相同分组依据的等于 0 的总和？

Question

是否可以删除总和为 0 的行？

这是表格:

+-----------+--------------+
| Subledger | ActualAmount |
+-----------+--------------+
| WWE12     | -25775       |
| WWE12     | -217         |
| WWE12     | -43          |
| WWE12     | 260          |
| WWE12     | 48994        |
+-----------+--------------+

期望的结果应该是:

+-----------+--------------+
| Subledger | ActualAmount |
+-----------+--------------+
| WWE12     | -217         |
| WWE12     | -43          |
| WWE12     | 260          |
+-----------+--------------+

非常感谢对此的任何帮助。

非常感谢!

这很做作，因为我事先知道总和由 3 个值组成，但无论如何......

SELECT x.*
  FROM 
     ( SELECT DISTINCT GROUP_CONCAT(DISTINCT c.actualamount ORDER BY c.actualamount) members
            , SUM(DISTINCT c.actualamount) total
         FROM my_table a 
         JOIN my_table b 
           ON b.actualamount NOT IN (a.actualamount)
         JOIN my_table c 
           ON c.actualamount NOT IN (a.actualamount,b.actualamount) 
        GROUP 
           BY a.actualamount
            , b.actualamount
       HAVING total = 0
     ) n
  JOIN my_table x
    ON FIND_IN_SET(actualamount,members) > 0;
