mysql - 函数计数数据结果以逗号分隔

Question

我有以下 SQL:

SELECT count(clics)
FROM clicscount
WHERE date > CURDATE() - INTERVAL 1 WEEK 

结果是上周点击次数的总和。

示例源数据:

Thursday:  5 clics
Friday:    5 clics
Saturday:  5 clics
Sunday:    5 clics
Monday:    5 clics
Tuesday:   5 clics
Wednesday: 5 clics
Today:     5 clics

显示的结果是 40，因为该函数显示的是所有点击的总和。

但是我想以每天点击的数组形式显示数据，例如:

5,5,5,5,5,5,5,5

Answer 1

你可以这样做:

SELECT GROUP_CONCAT(tmp.c SEPARATOR ',')
FROM (
  SELECT count(clics) c
  FROM clicscount
  WHERE date > CURDATE() - INTERVAL 1 WEEK 
  GROUP BY date
) as tmp;
