ArcGIS10中怎么在数据库查看ArcCatalog设置图层的元数据信息

因为ArcGIS10的Schema和ArcGIS9的Schema发生了很大的变化，详细可以查看： Geodatabase10新特性 ArcSDE10新特性-系统表解析 下面我们介绍一下怎么在数据库里面查看，以Oracle数据库为例，因为SQL Server比较简单，直接查看即可 假如说我们对ArcSDE里面的一个

Geodatabase10新特性

ArcSDE10新特性-系统表解析

下面我们介绍一下怎么在数据库里面查看，以Oracle数据库为例，因为SQL Server比较简单，直接查看即可

假如说我们对ArcSDE里面的一个名字叫ter1的要素类设置相关的元数据信息

为了好辨认，我就使用了上面的信息

那么我们在数据库中查询

C:\Users\Administrator>sqlplus sde/sde@orcl

SQL*Plus: Release 11.2.0.1.0 Production on 星期三 5月 23 15:55:46 2012

Copyright (c) 1982, 2010, Oracle.  All rights reserved.


连接到:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> select documentation from gdb_items where name ='TEST.ter1';

DOCUMENTATION
-------------
          311

登录SDE用户，然后在GDB_ITEMS表中查询指定要素类的DOCMENTATION，如果是SQL Server，直接点击可以查看，如果是Oracle，我们可以看到一个数字，该数字是在sde_xml_doc2表里面对应相关的信息

SQL> select sde.sdexmltotext(xml_doc) as xml from sde_xml_doc2 where sde_xml_id=311;

在SQL PLUS里面显示不是特别好，我们直接在PL/SQL里面查看XML 结构即可
