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 Refresh method updates a SQL Distributed Management Objects (SQL-DMO) object or collection with current values from the referenced instance of Microsoft SQL Server.
When Release is TRUE, all references maintained on a collection member, and any collections or objects within the member's tree, are released by force by SQL-DMO. SQL-DMO objects used by the application are invalid. SQL-DMO retrieves member object property values and refreshes the member object collection on the next application access to the object.
When Release is FALSE (default), application-maintained references are released only when the reference is on an object exposing a deleted or removed SQL Server component. Accessing a member object does not refresh member property values or contained collections.
Use caution when using the Refresh method. In general, it is best to override the default value for the Release argument, as forcing reference release ensures that all objects within a hierarchy represent the current state of an instance of SQL Server.
Limit the scope of the Refresh method to optimize its execution. For example, use the Refresh method of a Table object to update the application image of properties of a specific SQL Server table when applicable, rather than using the Refresh method of Tables collection indiscriminately.
