在你要導出數據字典的數據空中右鍵，新建查詢，執行如下代碼即可 

復制代碼代碼如下:

SELECT 
(case when a.colorder=1 then d.name else '' end)表名,d.xtype as 表類型, 
a.colorder 字段序號, 
a.name 字段名, 
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 標識, 
(case when (SELECT count(*) 
FROM sysobjects 
WHERE (name in 
(SELECT name 
FROM sysindexes 
WHERE (id = a.id) AND (indid in 
(SELECT indid 
FROM sysindexkeys 
WHERE (id = a.id) AND (colid in 
(SELECT colid 
FROM syscolumns 
WHERE (id = a.id) AND (name = a.name))))))) AND 
(xtype = 'PK'))>0 then '√' else '' end) 主鍵, 
b.name 類型, 
a.length 占用字節數, 
COLUMNPROPERTY(a.id,a.name,'PRECISION') as 長度, 
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小數位數, 
(case when a.isnullable=1 then '√'else '' end) 允許空, 
isnull(e.text,'') 默認值, 
isnull(g.[value],'') AS 字段說明 
FROM syscolumns a left join systypes b 
on a.xtype=b.xusertype 
inner join sysobjects d 
on a.id=d.id and d.xtype in ('U','V') 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.major_id 
order by a.id,a.colorder
