CancelAlter 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 CancelAlter method marks the end of a unit of change for the object referenced and discards any changes made to object property values.

语法

object
.CancelAlter( )

Parts

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

Prototype (C/C++)

HRESULT CancelAlter();

备注

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 2000 component. Group multiple changes by calling the BeginAlter method.

All changes made after the BeginAlter method call are submitted to SQL Server the next time DoAlter is called. Changes are discarded if the CancelAlter method is called.

注意：
Calling CancelAlter restores the SQL-DMO object referenced to its state at the time of the BeginAlter call. It does not refresh the object with current values from an instance of SQL Server.
