Hinweise

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.

Hinweis
The IsObjectDeleted method can be used with SQL Server 7.0, and Microsoft SQL Server 2000 or later.
