SQL查詢今天、昨天、n天內、第n天的數據, 本周，本月，上一個月的數據

• 查詢當天的所有數據

SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())=0

• 查詢昨天的所有數據

SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())=-1

• 查詢未來第n天的所有數據

//當n為負數時，表示過去第n天的數據 SELECT * FROM 表名WHERE DATEDIFF(字段,NOW())=n

• 查詢未來n天內所有數據

//n天內 SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())<n AND DATEDIFF(字段,NOW())>=0

• 查詢過去n天內所有數據

//包含當天 SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())<=0 AND DATEDIFF(字段,NOW())>-n //不包含當天 SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())<0 AND DATEDIFF(字段,NOW())>-n

查詢當天數據:

 SELECT * FROM 表名 WHERE TO_DAYS(表中時間字段) = TO_DAYS(NOW());

查詢當周數據：

 SELECT * FROM 表名 WHERE YEARWEEK(DATE_FORMAT(表中時間字段，‘%Y-%m-%d’)) = YEARWEEK(NOW());

查詢當月數據：

 SELECT * FROM 表名 WHERE YEARWEEK(DATE_FORMAT(表中時間字段，‘%Y-%m’)) = DATE_FORMAT(CURDATE(),'%Y-%m');

查詢最近一周數據：

 SELECT * FROM 表名 WHERE DATE_SUB(CURDATE(),INTERVAL 1 WEEK) <= DATE(表中時間字段)；

查詢最近一月內的數據：

 SELECT * FROM 表名 WHERE DATE_SUB(CURDATE(),INTERVAL 1 MONTH) <= DATE(表中時間字段)；

今天

select * from 表名 where to_days(時間字段名) = to_days(now());

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1

近7天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(時間字段名)

近30天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(時間字段名)

本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 時間字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )

上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 時間字段名, '%Y%m' ) ) =1

查詢本季度數據

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());

查詢上季度數據

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查詢本年數據

select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());

查詢上年數據

select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));

查詢當前這周的數據

SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());

查詢上周的數據

SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;

查詢上個月的數據

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 

查詢當前月份的數據 

select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

查詢距離當前現在6個月的數據

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

-- select * from 表名 where YEARWEEK(date) = YEARWEEK(now()) and DATEDIFF(date,NOW())<0

-- 查看當前這周的數據 不包含今天的之前數據

 

-- SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(date) and YEARWEEK(date) != YEARWEEK(now()) and DATEDIFF(date,NOW())<0

-- 近一個月數據 不包含本周的之前數據
