查询数据库中表名和扩展属性

在写系统概要设计时，需要展示数据结构（表名和扩展属性）。为了操作方便，创建了一张临时表输出表名和扩展属性

/**查询数据库中表名和扩展属性值**/

--临时表用来存表名和扩展属性值
if exists(select*from tempdb..sysobjects where id=OBJECT_ID('tempdb..#temp'))
drop table #temp
go
create table #temp
(
    name varchar(1000),
    value varchar(1000)
)
go

--用游标把数据中的表名和扩展属性查询出来 并插入到临时表中
declare @name varchar(100)
declare @value varchar(100)
declare select_proterty cursor for (select name from sysobjects where xtype='U')
open select_proterty 
fetch next  from select_proterty into @name
while @@fetch_status=0
begin
select @value=CAST(value as varchar) from sys.fn_listextendedproperty  
(default,'schema', 'dbo', 'table', @name, null, null)
insert into #temp values(@name,@value)
fetch next from select_proterty into @name
end
select * from #temp
close select_proterty 
deallocate select_proterty 
go   

二

select b.[value] from sys.columns a left join sys.extended_properties b on a.object_id=b.major_id 
and a.column_id=b.minor_id inner join sysobjects c on a.column_id=c.id 
and a.[name]='列名' and c.[name]='表名' 
SELECT 
表名=case when a.colorder=1 then d.name else '' end, 
表说明=case when a.colorder=1 then isnull(f.value,'') else '' end, 
字段序号=a.colorder, 
字段名=a.name, 
标识=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end, 
主键=case when exists(SELECT 1 FROM sysobjects where xtype='PK' and name in ( 
SELECT name FROM sysindexes WHERE indid in( 
SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid 
))) then '√' else '' end, 
类型=b.name, 
占用字节数=a.length, 
长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'), 
小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0), 
允许空=case when a.isnullable=1 then '√'else '' end, 
默认值=isnull(e.text,''), 
字段说明=isnull(g.[value],'') 
FROM syscolumns a 
left join systypes b on a.xusertype=b.xusertype 
inner join sysobjects d on a.id=d.id and d.xtype='U' and d.name<>'dtproperties' 
left join syscomments e on a.cdefault=e.id 
left join sys.extended_properties g on a.id=g.major_id and a.colid=g.minor_id 
left join sys.extended_properties f on d.id=f.major_id and f.minor_id=0 
where d.name='QB_Exam' 
order by a.id,a.colorder
