1、MSSQL2000
復制代碼 代碼如下:

SELECT
表名 = case when a.colorder=1 then d.name else '' end,
表說明 = case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序號 = a.colorder,
字段名 = a.name,
標識 = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,
主鍵 = case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id 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,
類型 = b.name,
占用字節數 = a.length,
長度 = COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小數位數 = isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允許空 = case when a.isnullable=1 then '√'else '' end,
默認值 = isnull(e.text,''),
字段說明 = 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
sysproperties g
on
a.id=g.id and a.colid=g.smallid
left join
sysproperties f
on
d.id=f.id and f.smallid=0
where
d.name='FI_dept' --如果只查詢指定表,加上此條件
order by

a.id,a.colorder


2、MSSQL2005

use test--數據庫
go
--2005實現字段屬性統計(2000里的系統表sysproperties描述表、字段不存在,2005里用sys.extended_properties視圖替代)
select
[表名]=c.Name,
[表說明]=isnull(f.[value],''),
[列名]=a.Name,
[列序號]=a.Column_id,
[標識]=case when is_identity=1 then '√' else '' end,
[主鍵]=case when exists(select 1 from sys.objects where parent_object_id=a.object_id and type=N'PK' and name in
(select Name from sys.indexes where index_id in
(select indid from sysindexkeys where and colid=a.column_id)))
then '√' else '' end,
[類型]=b.Name,
[字節數]=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,
[長度]=ColumnProperty(a.object_id,a.Name,'Precision'),
[小數]=isnull(ColumnProperty(a.object_id,a.Name,'Scale'),0),
