Remarks

GetColumnSQLVARIANTToString can be useful in applications designed to display the contents of sql_variant columns, such as a Web site.

Columns with underlying numeric, decimal, or datetime data types cannot be converted to strings using the GetColumnSQLVARIANTToString method.

Note  If an application calls GetColumnSQLVARIANTToString on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000" are returned.
