Comentários

SQL Server defines base data types, such as varchar or smallint. The types constrain data in SQL Server columns to certain fundamental properties, such as numeric precision or value representation. SQL Server base data types have an established precedence for mixed-data type arithmetic performed on an instance of SQL Server.

A SystemDatatype object exists for each base data type defined by SQL Server.

The Name property of a SystemDatatypecannot be set by the user.

Observação
The SystemDatatype object is compatible with instances of SQL Server versions 7.0 and later. However, the SystemDatatype2 object extends the functionality of the SystemDatatype object for use with features that were introduced in SQL Server 2000.
