直接上代码： CREATE FUNCTION UNIX_TIMESTAMP (@ctimestamp datetime) RETURNS integer ASBEGIN / Function body / declare @return integer SELECT @return = DATEDIFF(SECOND,{d '1970-01-01'}, @ctimestamp) return @returnENDCREATE FUNCTION fr

                        <p>直接上代码：</p>

CREATE FUNCTION UNIX_TIMESTAMP (@ctimestamp datetime) RETURNS integer AS BEGIN / Function body / declare @return integer SELECT @return = DATEDIFF(SECOND,{d '1970-01-01'}, @ctimestamp) return @return END

CREATE FUNCTION from_unixtime (@ts integer) RETURNS datetime AS BEGIN / Function body / declare @return datetime select @return = DATEADD(second, @ts, {d '1970-01-01'}) return @return END

用法

跟MySQL下的一样类似：

select dbo.UNIX_TIMESTAMP('2013-1-1') select dbo.from_unixtime(2145000000)
