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 SystemObject property returns TRUE for Microsoft SQL Server database objects whose implementation is owned by Microsoft.
If TRUE, the database object is defined by Microsoft as part of an instance of SQL Server.
If FALSE, the database object has been created by a SQL Server user and object ownership rules apply. Specifically, ownership for the database object is assigned at object creation, and for some objects it can be transferred to another user.
