MySQL中獲取天、周、月等數據
1.今天
select * from 表名 where to_days(時間字段名) = to_days(now());
2.昨天
SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1
3.近7天
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(時間字段名)
4.近30天
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(時間字段名)
5.本月
SELECT * FROM 表名 WHERE DATE_FORMAT( 時間字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )
6.上一月
SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 時間字段名, '%Y%m' ) ) =1
7.查詢本季度數據
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());
8.查詢上季度數據
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));
9.查詢本年數據
select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());
10.查詢上年數據
select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));
11.查詢當前這周的數據
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());
查詢本周所有的數據(本周第一天是周一)
SELECT * FROM task WHERE YEARWEEK(date_format(時間字段,'%Y-%m-%d'),1) = YEARWEEK(now(),1);
查詢本周所有的數據(本周第一天是周日)
SELECT * FROM task WHERE YEARWEEK(date_format(時間字段,'%Y-%m-%d')) = YEARWEEK(now());
12.查詢上周的數據
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;
13.查詢上個月的數據
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
14.查詢當前月份的數據
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')
15.查詢距離當前現在6個月的數據
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();
select curdate(); --獲取當前日期
select last_day(curdate()); --獲取當月最后一天。
select DATE_ADD(curdate(),interval -day(curdate())+1 day); --獲取本月第一天
select date_add(curdate()-day(curdate())+1,interval 1 month); -- 獲取下個月的第一天
select DATEDIFF(date_add(curdate()-day(curdate())+1,interval 1 month ),DATE_ADD(curdate(),interval -day(curdate())+1 day)) from dual; --獲取當前月的天數
