***mysql中查询今天、昨天、上个月sql语句

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

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;

查询当前月份的数据

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

查询距离当前现在6个月的数据

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

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 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

where   date(regdate)   =   curdate();

select   *   from   test   where   year(regdate)=year(now())   and   month(regdate)=month(now())   and   day(regdate)=day(now())

SELECT date( c_instime ) ,curdate( )

WHERE 1

MSSQL获取昨天，本周，本月。。。

特别说明下：以下统计本周数据时，星期天是作为下周的第一天，而不是本周最后一天，因此你把星期天作为本周最后一天时，你需要在getDate()的基础上减一天,如dateadd('day', -1, getDate())

本周：select * from table where datediff(week,C_CALLTIME,getdate())=0 --C_CALLTIME 为日期字段

本月：select * from table where datediff(Month,C_CALLTIME,getdate())=0 --C_CALLTIME 为日期字段

本季：select * from table where datediff(qq,C_CALLTIME,getdate())=0

前半年1-6，后半年7-12：select * from table where datepart(mm,C_CALLTIME)/7 = datepart(mm,getdate())/7

昨天

select convert(varchar(10),getdate() - 1,120)

明天

select convert(varchar(10),getdate() + 1,120)

最近七天

select * from tb where 时间字段 >= convert(varchar(10),getdate() - 7,120)

随后七天

select * from tb where 时间字段 <= convert(varchar(10),getdate() + 7,120) and 时间字段 >= 时间字段

convert和dateadd函数结合使用就可以了。

用datediff(day,时间列,getdate())

上月

select * from tb where month(时间字段) = month(getdate()) - 1

本月

select * from tb where month(时间字段) = month(getdate())

下月

select * from tb where month(时间字段) = month(getdate()) + 1

--如果是在表中查詢

--昨天

Select * From TableName Where DateDiff(dd, DateTimCol, GetDate()) = 1

--明天

Select * From TableName Where DateDiff(dd, GetDate(), DateTimCol) = 1

--最近七天

Select * From TableName Where DateDiff(dd, DateTimCol, GetDate()) <= 7

--随后七天

Select * From TableName Where DateDiff(dd, GetDate(), DateTimCol) <= 7

--上周

Select * From TableName Where DateDiff(wk, DateTimCol, GetDate()) = 1

--本周

Select * From TableName Where DateDiff(wk, DateTimCol, GetDate()) = 0

--下周

Select * From TableName Where DateDiff(wk, GetDate(), DateTimCol ) = 1

--上月

Select * From TableName Where DateDiff(mm, DateTimCol, GetDate()) = 1

--本月

Select * From TableName Where DateDiff(mm, DateTimCol, GetDate()) = 0

--下月

Select * From TableName Where DateDiff(mm, GetDate(), DateTimCol ) = 1

--------------------------------------------------------

本周

select * from tb where datediff(week , 时间字段 ,getdate()) = 0

上周

select * from tb where datediff(week , 时间字段 ,getdate()) = 1

下周

select * from tb where datediff(week , 时间字段 ,getdate()) = -1

--------------------------------------------------------

1.现在我需要得到只是日期部分，时间部分不要，SQL怎么写？

select convert(varchar(10),getdate(),120)

2.求以下日期SQL:

昨天

select convert(varchar(10),getdate() - 1,120)

明天

select convert(varchar(10),getdate() + 1,120)

最近七天

select * from tb where 时间字段 >= convert(varchar(10),getdate() - 7,120)

随后七天

select * from tb where 时间字段 <= convert(varchar(10),getdate() + 7,120) and 时间字段 >= 时间字段
