DateTime2 with fractional seconds precision of 3 is same as DateTime data type.

  1. DECLARE @thedatetime2 datetime27, @thesmalldatetime smalldatetime; SET @. In the previous examples, the smalldateime value was assigned by setting it to the same value as the datetime2 value. When we do that, SQL Server performs an implicit conversion.
  2. There are probably very few use cases that would cause you to convert a datetime2 value to datetime in SQL Server. In particular, the datetime2 data type can be set to use the same storage size as datetime, but with higher precision. So in most cases you’d be better off with datetime2 than with a datetime.
  3. Many developers assume that converting to varbinary is representative of how SQL Server actually stores date and time values. However this is only partially true. While it’s true that SQL Server stores its date and time values in hexadecimal, that hex value doesn’t actually include the precision.
