有时候,我们需要统计数据。比如按月统计、按天统计。使用mysql如下:
按月统计:
select count(1) as 'total' ,sum(platform_share_fee) as 'totalmoney' from tbk_order group by date_format(pay_time, '%Y-%m');
按天统计:
select count(1) as 'total' ,sum(platform_share_fee) as 'totalmoney' , date_format(pay_time, '%Y-%m-%d') as 'pay_time' from tbk_order group by date_format(pay_time, '%Y-%m-%d')
按天,指定范围内统计:
select count(1) as 'total' ,sum(platform_share_fee) as 'totalmoney' , date_format(pay_time, '%Y-%m-%d') as 'pay_time' from tbk_order group by date_format(pay_time, '%Y-%m-%d') HAVING pay_time >= '2022-12-19' and pay_time <= '2022-12-21';
其他:
今天
select * from 表名 where to_days(时间字段名) = to_days(now());
昨天
SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1
7天
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)
近30天
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)
本月
SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )
上一月
SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 时间字段名, '%Y%m' ) ) =1
#查询本季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());
#查询上季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));
#查询本年数据
select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());
#查询上年数据
select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));
查询当前这周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());
查询上周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;
查询当前月份的数据
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')
查询距离当前现在6个月的数据
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();
查询上个月的数据
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m')
select * from ` user ` where DATE_FORMAT(pudate, ' %Y%m ' ) = DATE_FORMAT(CURDATE(), ' %Y%m ' ) ;
select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now())
select *
from user
where MONTH (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = MONTH (now())
select *
from [ user ]
where YEAR (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = YEAR (now())
and MONTH (FROM_UNIXTIME(pudate, ' %y-%m-%d ' )) = MONTH (now())
select *
from [ user ]
where pudate between 上月最后一天
and 下月第一天
where date(regdate) = curdate();
select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())
SELECT date( c_instime ) ,curdate( )
FROM `t_score`
WHERE 1
LIMIT 0 , 30

按周
select DATE_FORMAT(create_time,'%Y%u') weeks,count(caseid) count from tc_case group by weeks;
按月
select DATE_FORMAT(create_time,'%Y%m') months,count(caseid) count from tc_case group by months;
按天
select DATE_FORMAT(create_time,'%Y%m%d') days,count(caseid) count from tc_case group by days;
按小时
select DATE_FORMAT(create_time,'%Y%m%d%H') hours,count(caseid) count from tc_case group by hours;
DATE_FORMAT方法说明
格式:DATE_FORMAT(date,format)
根据format字符串格式化date值。下列修饰符可以被用在format字符串中:
%M 月名字(January……December)
%W 星期名字(Sunday……Saturday)
%D 有英语前缀的月份的日期(1st, 2nd, 3rd, 等等。)
%Y 年, 数字, 4 位
%y 年, 数字, 2 位
%a 缩写的星期名字(Sun……Sat)
%d 月份中的天数, 数字(00……31)
%e 月份中的天数, 数字(0……31)
%m 月, 数字(01……12)
%c 月, 数字(1……12)
%b 缩写的月份名字(Jan……Dec)
%j 一年中的天数(001……366)
%H 小时(00……23)
%k 小时(0……23)
%h 小时(01……12)
%I 小时(01……12)
%l 小时(1……12)
%i 分钟, 数字(00……59)
%r 时间,12 小时(hh:mm:ss [AP]M)
%T 时间,24 小时(hh:mm:ss)
%S 秒(00……59)
%s 秒(00……59)
%p AM或PM
%w 一个星期中的天数(0=Sunday ……6=Saturday )
%U 星期(0……52), 这里星期天是星期的第一天
%u 星期(0……52), 这里星期一是星期的第一天
%% 一个文字“%”。
按年汇总,统计:
select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y');
按月汇总,统计:
select sum(mymoney) as totalmoney, count(*) as sheets from mytable group by date_format(col, '%Y-%m');
按季度汇总,统计:
select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by concat(date_format(col, '%Y'),FLOOR((date_format(col, '%m')+2)/3));
select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by concat(date_format(col, '%Y'),FLOOR((date_format(col, '%m')+2)/3));
按小时:
select sum(mymoney) as totalmoney,count(*) as sheets from mytable group by date_format(col, '%Y-%m-%d %H ');
查询 本年度的数据:
SELECT * FROM mytable WHERE year(FROM_UNIXTIME(my_time)) = year(curdate())
查询数据附带季度数:
SELECT id, quarter(FROM_UNIXTIME(my_time)) FROM mytable;
查询 本季度的数据:
SELECT * FROM mytable WHERE quarter(FROM_UNIXTIME(my_time)) = quarter(curdate());
本月统计:
select * from mytable where month(my_time1) = month(curdate()) and year(my_time2) = year(curdate())
本周统计:
select * from mytable where month(my_time1) = month(curdate()) and week(my_time2) = week(curdate())
N天内记录:
WHERE TO_DAYS(NOW())-TO_DAYS(时间字段)<=N
