IsDeleted Property
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 IsDeleted property indicates whether the referenced object has been deleted from an instance of Microsoft SQL Server.

HRESULT GetIsDeleted(LPBOOL pRetVal);
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. For example, if a SQL-DMO application creates a Tables collection that contains the CustReport table, and another application subsequently deletes the CustReport table, the CustReport table remains in the SQL-DMO internal cache until the SQL-DMO application refreshes the Tables collection by calling the Refresh method. Until the internal cache is refreshed, if the SQL-DMO application calls the properties or methods of the CustReportTable object, SQL-DMO attempts to access the deleted table.
A SQL-DMO application can use the IsDeleted property to verify the existence of the object without calling the Refresh method, which requires a round trip from the computer running the application to the instance of SQL Server and then refreshes the entire collection of objects.
IsDeleted returns TRUE if the object has been deleted from the server. However, IsDeleted does not clean up the SQL-DMO internal cache. The application must call the Refresh method to perform the cleanup process.
Note
IsDeleted can be used with SQL Server 2005, SQL Server 2000, and SQL Server version 7.0.
