DoAlter Method

В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.

The DoAlter method marks the end of a unit of change for the object referenced and submits changes made to property values.

Синтаксис

object.DoAlter( )

Parts

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

Prototype (C/C++)

HRESULT DoAlter( );

Замечания

Outside of a BeginAlter/DoAlter block, each change to a SQL Distributed Management Objects (SQL-DMO) object causes a discrete update to the referenced Microsoft SQL Server component. Group multiple SQL-DMO changes by calling the BeginAlter method.

All SQL-DMO property changes made after the BeginAlter method are submitted to SQL Server the next time DoAlter is called on the object. Changes are discarded if the CancelAlter method is called.
