java代码  
select  
(case when a.colorder=1 then d.name else '' end) as 表名,  
a.colorder as 字段序号,  
a.name as 字段名,  
(case when columnproperty(a.id,a.name,'IsIdentity')=1 then '√' else '' end) as 标识,  
(case when  
    (select count(*) from sysobjects where  
        (name in  
            (select name from sysindexes where (id=a.id) and  www.atcpu.com
                (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) as 主键,  
b.name as 类型,  
a.length as 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) as 允许空,  
isnull(e.text,'') as 默认值,  
isnull(g.[value],'') as 字段说明  www.atcpu.com
from syscolumns a  
left join systypes b on a.xtype=b.usertype  
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 a.id=g.major_id and a.colid =g.minor_id  
where d.name='COM_SEQUENCE'  
order by a.id,a.colorder  

上面的比较复杂，下面是简化过的
java代码  
select  
(case when a.colorder=1 then d.name else '' end) as tableName,  
a.name as fieldName,  
isnull(g.[value],'') as fieldDes  
from syscolumns a  
inner join sysobjects d on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'  
left join sys.extended_properties g on a.id=g.major_id and a.colid =g.minor_id  
--where d.name=''  --要查询的表  
order by a.id,a.colorder
