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
