DateDate object represents any valid Gregorian calendar date between '0001-01-01' CE and '9999-12-31' CE.
TimeTime object returns values for any valid time of day based on a 24 hour clock between '00:00:00' and max '23:59:59:9999999'.
DateTimeOffsetDateTimeOffset returns valid Gregorian calendar date between `0001-01-01’ and ‘9999-12-31’ with any valid time of day based on a 24 hour format between ’00:00:00’ and max ’23:59:49.9999999’. Included in the DateTimeOffset is a time zone offset that must be between ‘-14:00’ and ‘+14:00’.
DateTime2DateTime2 is considered an extension of the existing DATETIME object with a large date range and large default fractional precision. Values that represent any valid Gregorian calendar date between ‘0001-01-01’ CE and ‘9999-12-31’ CE combined with any valid time of day based on a 24-hour clock.
UserDefinedTableTypeA SQL Server common language runtime (CLR) user-defined table type.
HierarchyIdHierarchyID type represents data in a hierarchy structure. For more information, see Tutorial: Using the hierarchyid Data Type
GeometryGeometry spatial type represents data in a Euclidean (flat) coordinate system.
GeographyGeography spatial type represents data in a round-earth coordinate system. The SQL Server geography data type stores ellipsoidal (round-earth) data, such as GPS latitude and longitude coordinates.. 

The SqlDataType enumeration class is served by the SqlDataType property.
