大家好，我是考100分的小小码 ，祝大家学习进步，加薪顺利呀。今天说一说Mysql 查询天、周，月，季度、年的数据[通俗易懂],希望您对编程的造诣更进一步.
select * from 表名 where to_days(时间字段名) = to_days(now());代码100分
昨天
代码100分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
代码100分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();
