MYSQL中按照季度、月份等分组

mysql中关于分组的使用

1.  

   select DATE_FORMAT(create_time,'%Y%u') weeks,count(caseid) count from tc_case group by weeks;

2.  

   select DATE_FORMAT(create_time,'%Y%m%d') days,count(caseid) count from tc_case group by days;

3.  

   select DATE_FORMAT(create_time,'%Y%m') months,count(caseid) count from tc_case group by months;

4.  

    

5.  

   1、按照月份：

6.  

   select sum(total_amount) as total, date_format(stat_date, '%Y-%m') from week_report WHERE `stat_date` BETWEEN '2016-11-02' AND '2017-04-30' group by date_format(stat_date, '%Y-%m');

7.  

   select sum(total_amount) as total,date_format(stat_date, '%Y-%m') from week_report WHERE `stat_date` BETWEEN '2016-12-11' AND '2016-12-22' group by date_format(stat_date, '%Y-%m');

8.  

   获得按照月份分组进行汇总的数据。

9.  

    

10.  

    concat()连接字符串

11.  

     

12.  

    -- month

13.  

    select CONCAT(YEAR(stat_date),'_',DATE_FORMAT(stat_date,'%m')) months ,sum(total_amount) as count_amount, sum(total_new_user) as count_new_user, sum(da_active_user) as count_active_user from xxx

14.  

    WHERE `stat_date` BETWEEN '2016-01-02' AND '2017-05-30' group by months;

15.  

     

16.  

    -- 季度

17.  

    select CONCAT(YEAR(stat_date),'_',quarter(stat_date)) qu,sum(total_amount) as count_amount, sum(total_new_user) as count_new_user, sum(da_active_user) as count_active_user from xxx

18.  

    WHERE `stat_date` BETWEEN '2016-01-02' AND '2017-05-30' group by qu;

19.  

     

20.  

    -- 周

21.  

    select CONCAT(YEAR(stat_date),'_',DATE_FORMAT(stat_date,'%U')) weeks,sum(total_amount) as count_amount, sum(total_new_user) as count_new_user, sum(da_active_user) as count_active_user from xxx

22.  

    WHERE `stat_date` BETWEEN '2016-01-02' AND '2017-05-30' group by weeks;

23.  

     

24.  

    -- 天

25.  

    select CONCAT(YEAR(stat_date),'_',DATE_FORMAT(stat_date,'%m'),'_',DATE_FORMAT(stat_date,'%d')) days, sum(total_amount) as count_amount, sum(total_new_user) as count_new_user, sum(da_active_user) as count_active_user from xxx

26.  

    WHERE `stat_date` BETWEEN '2016-01-02' AND '2017-05-30' group by days
