4.查询imp结果

[oracle@node1 ~]$ sqlplus xifenfei/xff
SQL*Plus: Release 11.2.0.3.0 Production on Wed Jan 18 16:45:10 2012
Copyright (c) 1982, 2011, Oracle.  All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP, Data Mining,
Oracle Database Vault and Real Application Testing options
SQL> select count(*) from TAB_UUM_COMPANY;
select count(*) from TAB_UUM_COMPANY
                     *
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> select * from tab;
no rows selected

通过实验知道，show=y表示展示imp导入的时候，会执行的相关语句(不包括insert语句)，而不会真正的在数据库中执行
