mssql2005,2008导出数据字典实现方法

在你要导出数据字典的数据空中右键，新建查询，执行如下代码即可


复制代码 代码如下:

select

(case when a.colorder=1 then d.name else ” end)表名,d.xtype as 表类型,

a.colorder 字段序号,

a.name 字段名,

(case when columnproperty( a.id,a.name,’isidentity’)=1 then ‘√’else ” end) 标识,

(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) 主键,

b.name 类型,

a.length 占用字节数,

columnproperty(a.id,a.name,’precision’) as 长度,

isnull(columnproperty(a.id,a.name,’scale’),0) as 小数位数,

(case when a.isnullable=1 then ‘√’else ” end) 允许空,

isnull(e.text,”) 默认值,

isnull(g.[value],”) as 字段说明

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
