MYSQL SQL怎么查询近7天一个月的数据

//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, &#39;%Y%m&#39; ) = DATE_FORMAT( CURDATE( ) , &#39;%Y%m&#39; )
//上一月
SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , &#39;%Y%m&#39; ) , date_format( 时间字段名, &#39;%Y%m&#39; ) ) =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,&#39;%Y-%m-%d&#39;)) = YEARWEEK(now());
//查询上周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,&#39;%Y-%m-%d&#39;)) = YEARWEEK(now())-1;
//查询上个月的数据
select name,submittime from enterprise where date_format(submittime,&#39;%Y-%m&#39;)=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),&#39;%Y-%m&#39;)
select * from user where DATE_FORMAT(pudate,&#39;%Y%m&#39;) = DATE_FORMAT(CURDATE(),&#39;%Y%m&#39;) ; 
select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,&#39;%y-%m-%d&#39;)) = WEEKOFYEAR(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,&#39;%Y-%m&#39;)=date_format(now(),&#39;%Y-%m&#39;)

select 
    user_id,
    user_name,
    createtime
from

where
    DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(createtime);

DATE_SUB(NOW(), INTERVAL 5 HOUR)

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

select * from 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1;
