DoAlter Method

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

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

語法

object.DoAlter( )

Parts

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

Prototype (C/C++)

HRESULT DoAlter( );

備註

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.
