mysql - 如何编写一个循环在mysql中进行计算

Question

这是我的基本mysql查询，用于计算每日用户数，所以我需要从2012-01-30到2012-02-19执行，而不是手动修改，有什么好的方法吗？

select count(distinct user) FROM video WHERE date >= '2012-01-30 00:00' AND date <= '2012-01-30 23:55';


select count(distinct user) FROM video WHERE date >= '2012-01-31 00:00' AND date <= '2012-01-31 23:55';

...

Answer 1

SELECT DATE(date) AS date, COUNT(DISTINCT user) FROM video
WHERE date >= '2012-01-30 00:00' AND date_pl <= '2012-02-19 00:00'
GROUP BY DATE(date)
