如何读取sql表中字段的描述？

[zjcxc]

SELECT
表名=case when a.colorder=1 then d.name else '' end,
表说明=case when a.colorder=1 then isnull(f.value,'') 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,''),
字段描述=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
left join sysproperties f on d.id=f.id and f.smallid=0
--where d.name='要查询的表' --如果只查询指定表,加上此条件
order by a.id,a.colorder

--简单一点就是这样:

SELECT
表名=case when a.colorder=1 then d.name else '' end,
表说明=case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序号=a.colorder,
字段名=a.name,
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 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='要查询的表' --如果只查询指定表,加上此条件
order by a.id,a.colorder

晕倒啊，看半天还是看不懂。
能否再简单点？比如我要查表a中的字段b和c的说明该怎么写？
谢谢

SELECT 字段名=a.name,字段说明=isnull(g.[value],'')
FROM syscolumns a
left join sysproperties g on a.id=g.id and a.colid=g.smallid
where a.id=object_id('表a')
and a.name in('b','c')

sp_help 'a'

谢谢两位，如果是access数据库该怎么办呢？

[zjcxc]

ACCESS应该只能在前台程序中,用字段的property属性中的caption属性来取得

[zjcxc]

具体的可以到ACCESS版去问问.
