In August 2008 Microsoft released the latest version of the database server software, SQL Server 2008. SQL Server 2008 includes a number of new features not found in SQL Server 2005, including: a terser T-SQL syntax; the new MERGE statement; new data types and functions; enhanced encryption and XML support. In previous versions, SQL Server had only two date-related data types: datetime and smalldatetime, both of which allow date and time values (the difference being that datetime allows for a larger range of possible dates and affords more precision on the time than smalldatetime, but at the cost of larger storage space). SQL Server 2008 introduces four new date data types: time, date, datetime2, and datetimeoffset. Previous versions of SQL Server offered two date data types: datetime and smalldatetime. These data types were sufficient for most applications, but could be cumbersome in certain cases. For instance, both data types have a date and time portion, which is great if that's what you want, but cumberson if all you need to store is just the date or just the time. Similarly, the date ranges imposed by these two data types - 1753-01-01 to 9999-12-31 for datetime and 1900-01-01 to 2079-06-06 for smalldatetime - are insufficient for a small percentage of applications.
