IsObjectDeleted Method
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 IsObjectDeleted method indicates whether the referenced object has been deleted from the database.

Remarks
If a client session creates an object using SQL Distributed Management Objects (SQL-DMO), and another client session subsequently deletes the object using another tool, the SQL-DMO application is unaware of the deletion. A SQL-DMO application can use the IsObjectDeleted method to determine if the object still exists by specifying the object type and object name. If the objectOwner parameter is not used, the application assumes that the object owner is the user currently logged in.
Note
The IsObjectDeleted method can be used with SQL Server 7.0, and Microsoft SQL Server 2000 or later.
