MySQL中查询某一天, 某一月, 某一年的数据代码详

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

SELECT  FROM 表名 WHERE DATEDIFF(字段,NOW())=-1; -- 同理，查询前天的就是-2

SELECT  FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)

SELECT  FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)

SELECT  FROM 表名 WHERE DATE_FORMAT( 时间字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )

SELECT  FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 时间字段名, '%Y%m' ) ) =1

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