mysql - 按组选择字段数

Question

我有一个表格，表格如下:

id | score | type
 1 |     1 |  "a"
 2 |     4 |  "b"
 3 |     2 |  "b"
 4 |    53 |  "c"
 5 |     8 |  "a"

我需要根据类型选择分数的计数。所以我的结果将是:

totalScore | type
         9 |  "a"
         6 |  "b"
        53 |  "c"

我尝试了 DISTINCT 和 GROUP BY 似乎都不起作用。我尝试过的 SQL:

SELECT * , COUNT(  `score` ) AS totalScore
FROM  `table`
GROUP BY  `type`

和

SELECT DISTINCT `type`, COUNT(score) as totalScore FROM `table`

但是这些好像都不行。

有人能帮忙吗？

嘘

Answer 1

这应该可以...

SELECT sum(score) AS total FROM table GROUP BY type
