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,

              (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
