CREATE FUNCTION UNIX_TIMESTAMP (@ctimestamp datetime) RETURNS integerASBEGIN /* Function body */ declare @return integer SELECT @return = DATEDIFF(SECOND,{d '1970-01-01'}, @ctimestamp) return @returnENDCREATE FUNCTION from_unixtime (@ts integer) RETURNS datetime ASBEGIN /* Function body */ declare @return datetime select @return = DATEADD(second, @ts, {d '1970-01-01'}) return @returnEND |
用法
跟MySQL下的一样类似：

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