在企业管理—表—设计表
------解决方案--------------------
select * from sysobjects where xtype= 'v '--获得所有试图的基本信息
select * from syscolumns where id=object_id( '视图名字 ')--获得指定试图的列信息
------解决方案--------------------



select b.* from sysobjects a join syscolumns b
on a.id = b.id
where a.xtype= 'v ' and a.name = 'tableName '
