Sql Server 查询

SQL Server 2005:
架构dbo的所有表

	
select t.[name] as tablename, s.[name] as [schema] from sys.tables as t,sys.schemas as s where t.schema_id = s.schema_id
and s.[name] = 'dbo'




架构dbo的所有视图

	
select v.[name] as viewname, s.[name] as [schema] from sys.views as v,sys.schemas as s where v.schema_id = s.schema_id
and s.[name] = 'dbo'
