查询近一个月，一年，一周的数据

---

前言

由于这几天遇到了一些关于查询的问题，主要还是筛选数据，客户要求我们提供一下最近一个月的数据，开始的时候一直在想思考到底怎么筛选，经过不断的思考，以及查询到网上的一些内容之后，发现了一位大佬很厉害，写了关于这些查询的sql，今天我就直接借鉴一下了。

一、MySQL查询最近一个月的数据？

//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, '%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')

近一个月统计SQL

select 
    user_id,
    user_name,
    createtime
from
    t_user
where
    DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(createtime);

同理，近一个星期为: INTERVAL 7 DAY。
