这几天,在做数据统计,在对数据库数据进行统计过程中,有个需求就是要按照指定天数进行分组,

 

之前一直没有找到好的方法,就先取出数据,在程序中进行分组。

 

后发现,可以在SQL语句中实现按天数分组。

 

例:

 指定天数11天进行分组统计,例子中加上YEAR(date)* 1000,是为了区分年份

 

 1 SELECT 2     job_id, 3     SUM(`count`)AS total, 4     COUNT(job_id)AS countNum, 5     ( 6         YEAR(date)* 1000 + DAYOFYEAR(date) p 11 7     )AS groupNum 8 FROM 9     job_logs10 WHERE11     job_id = 112 GROUP BY13     groupNum
Copy after login
