Refresh Method

この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

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.

構文

object.Refresh( [ Release ] )

Parts

• object
  Expression that evaluates to an object in the Applies To list.

• Release
  TRUE or FALSE as described in Settings.

Prototype (C/C++)

HRESULT Refresh(BOOL bReleaseMemberObjects = FALSE);

Settings

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.

説明

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.
