我正在使用sql management studio，这是我的修改视图，如何向此行添加刷新命令，以便视图始终反映最新的记录

Answer 1

你不必这样做。视图不是表，它们是预定义的查询。

当您从视图中选择时，SQL Server会在那时执行视图的查询。

您可以通过创建视图，从中进行选择，然后向基表添加行并再次从视图中进行选择来对此进行测试。

Answer 2

如果对基础表进行更改，则需要刷新视图以查看反映的更改，但我很确定您无法在alter语句中执行此操作。

sp_refreshview [dbo].[pais2k1view]

然后，您可以在对数据库进行更改时手动运行它，或者将其包含在脚本中，您必须在调用查询查询之前将其自动化到某个位置。
