BulkCopy2 Object
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 BulkCopy2 object represents the parameters of a single bulk copy command issued against a Microsoft SQL Server database (SQL Server 2000 or later) and extends the functionality of the BulkCopy object.
注释
The BulkCopy2 object extends the functionality of the BulkCopy object for use with features that were added in SQL Server 2000. It also inherits the properties and methods of the BulkCopy object.
The TableLock property of the BulkCopy2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For information about using the BulkCopy2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section of the TableLock property. For more information, see Programming Extended SQL-DMO Objects.
