我想建立一个能够恢复我已经拥有的银的纸面。 我愿在没有内部数据的情况下重新计算亚洲开发银行。
因此,在出口用户的银时,是否有任何plus?

有两个基本办法。
首先是出口垃圾堆放地。 这可与数据消耗用途有关:
$ expdp apc/pw directory=data_dump_dir dumpfile=apc_20100707.dmp content=METADATA_ONLY
摘录更多。
在Oracle10g采用数据泵。 在数据库的较早版本中,我们可以使用EXP效用做同样的事情。
$ exp apc/pw dumpfile=apc_20100707.dmp rows=N
为输入文档,我们使用配对器impdp
(或imp/code>)。
这就是本组织的做法。 为了产生实际文字,我们可以使用Oracle 9i介绍的DBMS-METADATA包。 这是一项比以往更多的工作,但对出口物品的细节进行更严格的控制。 摘录更多。
dbms_metadata/code>的包件,可生成
create table
页: 1 例:
set pagesize 0
set long 90000
set feedback off
set echo off
spool filename.sql
connect username/password;
SELECT DBMS_METADATA.GET_DDL( TABLE ,u.table_name)
FROM USER_TABLES u;
SELECT DBMS_METADATA.GET_DDL( INDEX ,u.index_name)
FROM USER_INDEXES u;
spool off;
如以下所述,你还可以利用开发商制作Sql scripts:。
