Mysql 电商常用的时间操作（当天，昨天，7天，30天，半年，全年，季度等等）

1 、 查看当天日期

select current_date();

2、 查看当天时间

select current_time();

3、查看当天时间日期

1	select current_timestamp();

4、查询当天记录

1 2	select * from 表名 where to_days(时间字段名) = to_days(now());

5、查询昨天记录

 

1 2	SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) – TO_DAYS( 时间字段名) <= 1

6、查询7天的记录

 

1 2	SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)

7、查询近30天的记录

 

1 2	SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)

8、查询本月的记录

 

1 2	SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, ‘%Y%m’ ) = DATE_FORMAT( CURDATE( ) , ‘%Y%m’ )

9、查询上一月的记录

 

1 2	SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , ‘%Y%m’ ) , date_format( 时间字段名, ‘%Y%m’ ) ) =1

10、查询本季度数据

 

1 2	select * from 表名 where QUARTER(create_date)=QUARTER(now());

11、查询上季度数据

 

1 2	select * from 表名 where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

12、查询本年数据

 

1 2	select * from 表名   where YEAR(create_date)=YEAR(NOW());

13、查询上年数据

 

1 2	select * from 表名 where year(create_date)=year(date_sub(now(),interval 1 year));

14、查询当前这周的数据

 

1 2	SELECT * FROM 表名 WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());

15、查询上周的数据

 

1 2	SELECT * FROM 表名 WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;

16、查询当前月份的数据

 

1 2	select * from 表名   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

17、查询距离当前现在6个月的数据

 

1 2	select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

18、查询俩个时间之内的订单数据，或者流水。

 

1 2 3 4 5 6 7

SELECT yoaf.* from yun_order_account_flow yoaf WHERE 1=1 -- AND ( yoaf.flow_number='20170322180027377727111' OR yoaf.order_number='20170322180027377727111' ) -- AND yoaf.`status` ='1' AND yoaf.created_time<date_format('2017-03-25','%Y-%m-%d') AND yoaf.created_time>=date_format('2017-03-21','%Y-%m-%d') ;

或者通过between，有个缺点就是俩个值必须要存在。

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

SELECT yoi.id, yoi.order_number AS orderNumber, yoi.dispatching_type AS dispatchingType, yoi.address_id AS addressId, yoi.created_time AS createdTime, yoi. STATUS AS orderStatus, yoi.restaurant_id AS restaurantId, yai. NAME userName, yai.address address, yai.cellphone FROM yun_order_info yoi LEFT JOIN yun_address_info yai ON yoi.address_id = yai.id WHERE 1 = 1 -- AND yoi. STATUS = '1' AND yoi.created_time  BETWEEN date_format('2017-03-21','%Y-%m-%d') AND date_format('2017-03-24','%Y-%m-%d') LIMIT 0,10
