<div>--SQL 2005数据库结构显示--数据字典

-------------------------------------
use leamon_test --数据库名
go
--2005实现数据库表字段属性统计(2000里的系统表sysproperties描述表不存在，2005里用sys.extended_properties视图替代)
select 
[表名]=c.Name,
[表说明]=isnull(f.[value],''),
[列名]=a.Name,
[列序号]=a.Column_id,
[标识]=case when is_identity=1 then '&radic;' else '' end,
[主键]=case when exists(select 1 from sys.objects x join sys.indexes y on x.Type=N'PK' and x.Name=y.Name 
join sysindexkeys z on z.ID=a.Object_id and z.indid=y.index_id and z.Colid=a.Column_id)
then '&radic;' else '' end,
[类型]=b.Name,
[字节数]=case when a.[max_length]=-1 and b.Name!='xml' then 'max/2G' 
when b.Name='xml' then '2^31-1字節/2G'
else rtrim(a.[max_length]) end,
[长度]=case when ColumnProperty(a.object_id,a.Name,'Precision')=-1 then '2^31-1'
else rtrim(ColumnProperty(a.object_id,a.Name,'Precision')) end,
[小数]=isnull(ColumnProperty(a.object_id,a.Name,'Scale'),0),
[是否为空]=case when a.is_nullable=1 then '&radic;' else '' end,
[列说明]=isnull(e.[value],''),
[默认值]=isnull(d.text,'') 
from 
sys.columns a
left join
sys.types b on a.user_type_id=b.user_type_id
inner join
sys.objects c on a.object_id=c.object_id and c.Type='U'
left join
syscomments d on a.default_object_id=d.ID
left join
sys.extended_properties e on e.major_id=c.object_id and e.minor_id=a.Column_id and e.class=1 
left join
