SystemDatatype Object

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

The SystemDatatype object exposes the attributes of a Microsoft SQL Server base data type.

SQL-DMO object model that shows the current object

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.

NoteNote

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.
