如何用ＳＱＬ语句取得数据库sql2005中的所有数据表中每一个字段的描述信息呢？(高手请进入!!)

方法一:
SELECT

表名=case when a.colorder=1 then d.name else '' end,
字段序号=a.colorder,
字段名=a.name,
标识=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√' else '' end,
主键=case when exists(SELECT 1 FROM sysobjects where xtype='PK' 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,
类型=b.name,
占用字节数=a.length,
长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允许空=case when a.isnullable=1 then '√'else '' end,
默认值=isnull(e.text,''),
字段说明=isnull(g.[value],'')

FROM syscolumns a left join systypes b on a.xtype=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

where g.name='MS_Description'

order by a.id,a.colorder

网上查的,上面的程序在SQL2005下不能执行,主要是找不到sysproperties
以下为提示信息:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'dbo.sysproperties'.


方法二:
在VS2005中用类示GetSchemaTable(),有很多表的结构信息,却没有字段的描述信息Description,
可我要的就是字段的描述信息啊!!

难到SQL2005就找不出数据字典中的字段描述吗?

象sysproperties这样无正式文档记载的系统表还是不要用的好，
很有可能在SQL Server的新版本或者补丁正不在支持，在SQL 2005中使用sys.extended_properties

--修改后如下

SELECT
表名=case when a.colorder=1 then d.name else '' end,
字段序号=a.colorder,
字段名=a.name,
标识=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√' else '' end,
主键=case when exists(SELECT 1 FROM sysobjects where xtype='PK' 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,
类型=b.name,
占用字节数=a.length,
长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允许空=case when a.isnullable=1 then '√'else '' end,
默认值=isnull(e.text,''),
字段说明=isnull(g.[value],'')

FROM syscolumns a left join systypes b on a.xtype=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 sys.extended_properties g on d.id=g.major_id and a.colid=g.minor_id
--取消下面的注释则只返回有描述的字段
--where g.name='MS_Description'

order by a.id,a.colorder
