mysql> show create table byzp_personinfo;

CREATE TABLE `byzp_personinfo` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `birthday` date NOT NULL,
  `create_data` datetime(6),
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8 |

1.今天
select * from byzp_personinfo where to_days(birthday) = to_days(now());


2.昨天
select * from byzp_personinfo where to_days(NOW()) - TO_DAYS(birthday) <= 1;


3.近7天
select * from byzp_personinfo where date_sub(CURDATE(),INTERVAL 7 DAY) <= DATE(birthday);  


4.近30天
select * from byzp_personinfo where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(birthday);


5.本月
select * from byzp_personinfo WHERE DATE_FORMAT( birthday, '%Y%m' ) = DATE_FORMAT( CURDATE() , '%Y%m' );


6.上一月
select * from byzp_personinfo WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( birthday, '%Y%m' ) ) =1;


7.查询本季度数据
select * from byzp_personinfo where QUARTER(birthday)=QUARTER(now());

8.查询上季度数据
select * from byzp_personinfo where QUARTER(birthday)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));  


9.查询本年数据
select * from byzp_personinfo where YEAR(birthday)=YEAR(NOW());


10.查询上年数据
select * from byzp_personinfo where year(birthday)=year(date_sub(now(),interval 1 year));  


11.查询距离当前现在6个月的数据
select * from byzp_personinfo where birthday between date_sub(now(),interval 6 month) and now();  


12.查询当前这周的数据
select * from byzp_personinfo WHERE YEARWEEK(date_format(birthday,'%Y-%m-%d')) = YEARWEEK(now());  


13.查询上周的数据
select * from byzp_personinfo WHERE YEARWEEK(date_format(birthday,'%Y-%m-%d')) = YEARWEEK(now())-1;  


14.查询上个月的数据
select * from byzp_personinfo where date_format(birthday,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m');


15.查询当前月份的数据
select * from byzp_personinfo where DATE_FORMAT(birthday,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m');
select * from byzp_personinfo where date_format(birthday,'%Y-%m')=date_format(now(),'%Y-%m');


16.查询指定时间段的数据
select * from byzp_personinfo where birthday < '2018-4-1 00:00:00'  or birthday >'2018-10-31 00:00:00';   
select * from byzp_personinfo where birthday >= '2018-6-1 00:00:00' and birthday < '2019-1-1 00:00:00';

17.查询月份数据
语法：
        select * from table_name where month(date)='2';
示例：
        查询表byzp_personinfo中2月份生日的人
        select * from byzp_personinfo where month(birthday) = '2';

18.查询年份数据
语法：
        select * from table_name where year(date)=年份;
示例：
        查询表byzp_personinfo中2019年的数据
        select * from byzp_personinfo where year(birthday) = '2019';
