mysql 查詢某個時間段的數據

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

--昨天(包括昨天和今天的數據)
	SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1

--昨天(只包括昨天)
	SELECT * FROM 表名 WHERE DATEDIFF(字段,NOW())=-1;
-- 同理，查詢前天的就是-2

--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());

--查詢上週的數據
	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  上月最後一天  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();
