SQL只取日期的年月日部分

方法一:
select CONVERT(varchar, getdate(), 120 )
2004-09-12 11:06:08

select replace(replace(replace(CONVERT(varchar, getdate(), 120 ),\'-\',\'\'),\' \',\'\'),\':\',\'\')
20040912110608

select CONVERT(varchar(12) , getdate(), 111 )
2004/09/12

select CONVERT(varchar(12) , getdate(), 112 )
20040912

select CONVERT(varchar(12) , getdate(), 102 )
2004.09.12

select CONVERT(varchar(12) , getdate(), 101 )
09/12/2004

select CONVERT(varchar(12) , getdate(), 103 )
12/09/2004

select CONVERT(varchar(12) , getdate(), 104 )
12.09.2004

select CONVERT(varchar(12) , getdate(), 105 )
12-09-2004

select CONVERT(varchar(12) , getdate(), 106 )
12 09 2004

select CONVERT(varchar(12) , getdate(), 107 )
09 12, 2004

select CONVERT(varchar(12) , getdate(), 108 )
11:06:08

select CONVERT(varchar(12) , getdate(), 109 )
09 12 2004 1

select CONVERT(varchar(12) , getdate(), 110 )
09-12-2004

select CONVERT(varchar(12) , getdate(), 113 )
12 09 2004 1

select CONVERT(varchar(12) , getdate(), 114 )
11:06:08.177

方法二:
declare @tt varchar(4),@pp varchar(8) ,@ss varchar(4),@aa varchar(16)

set @tt=rtrim(cast(month(getdate()) as varchar(10)))
set @ss=rtrim(cast(day(getdate()) as varchar(10)))
select @pp=rtrim(cast(year(getdate()) as varchar(10)))
select @aa=@pp+@tt+@ss
select @aa

只顯示年月,不顯示日:select datepart(year,getdate())*100+datepart(month,getdate())
