请使用这样一条Sql语句,试试吧!

SELECT

  (case when a.colorder=1 then d.name else '' end)表名,

  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='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 

order by a.id,a.colorder
