如何计算 sqlite 中每个不同值有多少重复项?

2022-01-09 00:00:00 sum count distinct sqlite

我有一张桌子:

ref,type
1,red
2,red
3,green
4,blue
5,black
6,black

我希望 sqlite 查询的结果是:

I want the result of a sqlite query to be:

red,2 green,1 blue,1 black,2

我认为最难的事情是找到一个与我的问题相匹配的问题?那么我相信答案就在眼前......

I think the hardest thing to do is find a question to match my problem? Then I am sure the answer is around the corner....
