MySql按日期查找sql语句详解

在mysql中对时间日期操作的函数有很多,有时我们就希望直接通过sql查询出指定日期的数据了,下面小编来给大家总结一下.

使用DATE_FORMAT方法:SELECT * FROM `ler_items` WHERE DATE_FORMAT(postTime,'%Y-%m')='2013-03'

注意:日期一定要用'',否则没有效果,其它的一些关于mysql日期查找语句,代码如下:

1. mysql>selectdate_format(DATE_SUB(CURDATE(),INTERVAL7DAY),’%y%m%d’);
2. +———————————————————–+
3. |date_format(DATE_SUB(CURDATE(),INTERVAL7DAY),’%y%m%d’)|
4. +———————————————————–+
5. |120416|
6. +———————————————————–+
7. 1rowinset(0.00sec)

可以获取7天前的日期,使用DATE_SUB(CURDATE(), INTERVAL 7 DAY）来获得7天前的时间,用date_format 来指定输出格式.

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’)

1. select*from`user`whereDATE_FORMAT(pudate,‘%Y%m‘)=DATE_FORMAT(CURDATE(),‘%Y%m‘);
2. select*fromuserwhereWEEKOFYEAR(FROM_UNIXTIME(pudate,’%y-%m-%d’))=WEEKOFYEAR(now())
3. select*
4. fromuser
5. whereMONTH(FROM_UNIXTIME(pudate,‘%y-%m-%d‘))=MONTH(now())
6. select*
7. from[user]
8. whereYEAR(FROM_UNIXTIME(pudate,‘%y-%m-%d‘))=YEAR(now())
9. andMONTH(FROM_UNIXTIME(pudate,‘%y-%m-%d‘))=MONTH(now())//phpfensi.com
10. select*
11. from[user]
12. wherepudatebetween上月最后一天
13. and下月第一天
14. wheredate(regdate)=curdate();
15. select*fromtestwhereyear(regdate)=year(now())andmonth(regdate)=month(now())andday(regdate)=day(now())
16. SELECTdate(c_instime),curdate()
17. FROM`t_score`
18. WHERE1
