DoAlter Method

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

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

语法

object.DoAlter( )

Parts

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

Prototype (C/C++)

HRESULT DoAlter( );

注释

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.
