mysql时间区间查询索引_教你mysql查询大于某个日期

mysql时间区间查询索引_教你mysql查询大于某个日期 在很多地方都使用到了mysql的日期查询，如果不做处理，查询出来的是毫秒数，虽然就java能够处理，但是总归是要浪费时间，所以特地想总结一些关于日期查询相关的方法，供以后查询方便。

第一种：在sql中使用DATE_FORMAT进行格式化，得到的结果直接就是你设置的格式SELECT DATE_FORMAT(t.create_time,’%Y-%c-%d %H:%i:%s’) ‘date’ FROM e_mail_accept t得到的是：2018-12-08 16:36:47第二种：如果是使用的ssm项目，则可以通过在对应的pojo上面加上@JsonFormat注解，即可得到想要的结果/** 创建时间 */@JsonFormat(locale=”zh”, timezone=”GMT+8″, pattern=”yyyy-MM-dd HH:mm:ss”)@TableField(value=”create_time”)private Date createTime;此方法需要在maven加上如下代码<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.2</version></dependency>第三种：查询当前日期常用的sqlSELECT DATE_SUB(CURDATE(),INTERVAL 0 DAY) ;结果：2018-12-19SELECT NOW();结果：2018-12-19 22:11:53SELECT CURDATE();结果：2018-12-19查询昨天：2018-12-18SELECT DATE_SUB(CURDATE(),INTERVAL 1 DAY) ;查询明天：2018-12-19SELECT DATE_SUB(CURDATE(),INTERVAL -1 DAY) ;查询前一个小时：2018-12-19 21:19:10SELECT DATE_SUB(NOW(),INTERVAL 1 HOUR) ;查询后一个小时：2018-12-19 21:19:10SELECT DATE_SUB(NOW(),INTERVAL -1 HOUR) ;查询前一分钟：2018-12-19 22:19:08SELECT DATE_SUB(NOW(),INTERVAL 1 MINUTE) ;查询前一年：2017-12-19 22:19:08SELECT DATE_SUB(NOW(),INTERVAL 1 YEAR) ;第四种：查询时间段的时候，要确定是比较年月日还是比较到时分秒select * from test where date_format(create_time,’%Y-%m-%d’) between ‘2018-07-30’ and ‘2018-07-31’;第五种：常用的查询今天、昨天、最近几天、一个月、一个季度等数据查询此段参考了：https://www.cnblogs.com/benefitworld/p/5832897.html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近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();
