mysql按年月日查询_MySql按年月日分组查询

MySql日期的格式化

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

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

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

1、按照月份：

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');

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');

获得按照月份分组进行汇总的数据。

concat()连接字符串

-- month

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

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

-- 季度

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

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

-- 周

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

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

-- 天

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

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

或者

select date_format(create_date, '%Y-%m') as aa,SUM(operation_balance) as money from user_wallet_record where year(create_date) = 2019 group by month (create_date);
