MySQL：根据字段名称计算行数

Question

我的MySql db表结构是：

id | status
1  |  Open
2  |  Open
3  |  Closed
4  |  Open
5  |  Closed

我希望计算打开和关闭行的总数。

Status | Total
Open   |   3
Closed |   2

我用过

SELECT count(distinct status) as Total FROM my_tbl

但它返回

Total
  2

Answer 1

SELECT status,
COUNT(id) AS `total`
FROM your_table
GROUP BY status
ORDER BY total DESC
