	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 '&radic;'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 '&radic;' 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 '&radic;'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 sys.extended_properties g
	on a.id=g.major_id AND a.colid = g.major_id
	order by a.id,a.colorder
