使用 Count 查找出现次数

2021-11-20 00:00:00 sql group-by mysql

假设我有一个包含以下值的表格.

Let's say I have a table with the following values.

Ford
Ford
Ford
Honda
Chevy
Honda
Honda
Chevy

所以我想构造以下输出.

So I want to construct the following output.

Ford   3
Honda  3
Chevy  2

它只需要列中每个元素的计数.

It just takes the count of each element in the column.

我在列出唯一列时遇到问题.

I'm having an issue listing the unique columns.

谁能告诉我怎么做?

我已经把 UNIQUE 和 DISTINCT 弄乱了，但我不能获取左侧的值列表.

I've messed around with UNIQUE and DISTINCT, but I'm not able to get the list of values on the left.

推荐答案

你是这个意思吗?

select car_make, count(*) from cars
group by car_makes
