经常会遇到这样的情况，本月阅读排行榜，本周排行榜等等。那么这样的sql怎么写呢，小班收集了一些这样的时间函数给大家参考，希望大家在自己网站项目中可以用的到

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:

mysql>selectdate_format(DATE_SUB(CURDATE(), INTERVAL 7DAY),’%y%m%d’);

+———————————————————–+

| date_format(DATE_SUB(CURDATE(), INTERVAL 7 DAY),’%y%m%d’) |

+———————————————————–+

| 120416 |

+———————————————————–+

1 row inset(0.00 sec)

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’)
