BeginAlter 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 BeginAlter method marks the start of a unit of change for the object referenced.

语法

object.BeginAlter()

Parts

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

Prototype (C/C++)

HRESULT BeginAlter();

注释

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

All changes made after the BeginAlter method are submitted to SQL Server the next time the DoAlter method is called on the object.
