用Sql语句生成Sqlserver数据字典

   
SELECT  表名=case when a.colorder=1 then d.name 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 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
