select * from sysobjects where xtype= 'v '
[解决办法]
在企业管理—表—设计表
[解决办法]
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
[解决办法]
select b.* from sysobjects a join syscolumns b
on a.id = b.id
where a.xtype= 'v ' and a.name = 'tableName '
[解决办法]
select a.TableName, a.FieldName,
a.FieldType, a.FieldTypeName,
a.FieldWidth,a.xprec,
a.FieldDigits,a.name,
isnull(a.[value],b.value)FieldCaption, a.id, a.smallid,
