The IsOnComputed property is used in conjunction with indexed views and returns TRUE if any column in an index is a computed column.

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