我有一张这样的桌子:

+----+-------+-----------------+
| ID | Name  |      Email      |
+----+-------+-----------------+
|  1 | Jane  | Jane@doe.com    |
|  2 | Will  | Will@gmail.com  |
|  3 | Will  | wsj@example.com |
|  4 | Jerry | jj2@test.com    |
+----+-------+-----------------+

不幸的是,由于有多封电子邮件,我的记录重复。我想运行一个SQL查询来生成这个:

+----+-------+---------------------------------+
| ID | Name  |              Email              |
+----+-------+---------------------------------+
|  1 | Jane  | Jane@doe.com                    |
|  2 | Will  | Will@gmail.com, wsj@example.com |
|  4 | Jerry | jj2@test.com                    |
+----+-------+---------------------------------+

我知道用数字您会做类似的事情,但是我不知道如何对文本字段进行求和:

SELECT *,
   SUM(Number_Field) AS Number_Field,
FROM table

谢谢!
