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
