Also, DATETIME2 is more accurate than DATETIME. So I would recommend using DATETIME2 over DATETIME when possible. I think the only reason for using DATETIME over DATETIME2 is for backward compatibility. DateTime2 Syntax : DATETIME2 [ (fractional seconds precision) ] With DateTime2 Optional fractional seconds precision can be specified The precision scale is from 0 to 7 digits The default precision is 7 digits For precision 1 and 2, storage size is 6 bytes For precision 3 and 4, storage size is 7 bytes For precision 5, 6 and 7, storage size is 8 bytes Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_21.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_20.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
