這篇文章主要講解了“能select的表就可以exp嗎”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“能select的表就可以exp嗎”吧！

1.建立導(dǎo)出測試用戶，并授予相關(guān)權(quán)限

[oracle@GXDB1] $sqlplus /nolog

SQL*Plus: Release 10.2.0.4.0 - Production on Fri May 3 15:11:19 2013

Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.

SQL> conn / as sysdba
Connected.

SQL> create user test_exp identified by a;

User created.

SQL> grant connect to test_exp;

Grant succeeded.

SQL> grant select on dep_study.bas_region to test_exp;

Grant succeeded.

2.導(dǎo)出dep_study.bas_region表

[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region

Export: Release 10.2.0.4.0 - Production on Fri May 3 15:26:15 2013

EXP-00009: no privilege to export DEP_STUDY's table BAS_REGION
Export terminated successfully with warnings.
[oracle@GXDB1] $

3.給test_exp授予exp_full_database權(quán)限
SQL> grant exp_full_database to test_exp;

Grant succeeded.

4.成功導(dǎo)出表

[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region

Export: Release 10.2.0.4.0 - Production on Fri May 3 15:29:20 2013

About to export specified tables via Conventional Path ...
Current user changed to DEP_STUDY
. . exporting table                     BAS_REGION         17 rows exported
Export terminated successfully without warnings.

--ok 成功導(dǎo)出

5.收回select權(quán)限，并導(dǎo)出表

SQL>  revoke select on dep_study.bas_region from test_exp;

Revoke succeeded.

[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region

Export: Release 10.2.0.4.0 - Production on Fri May 3 15:32:15 2013

結(jié)論：

    exp其他用戶的表，用戶需要擁有select表和exp_full_database(角色)兩個權(quán)限。
