Oracle 11g Guide Library does not produce empty table problems

ORACLE11G will encounter such a problem, with the EXP whole library export, you will encounter such a problem, the empty table in the library can not be exported

SELECT * from All_all_tables AA where aa.owner= ' user name uppercase '---View all tables under User

SELECT * from All_tables t where T.owner = ' User name uppercase ' and t.num_rows = 0;--View all empty tables under User

OK, here's the processing method script:

Run in the command window:

Set heading off;
Set echo off;
Set feedback off;
Set termout on;
Spool D:\allocate.sql;
Select ' ALTER TABLE ' | | table_name| | ' allocate extent; ' from User_tables where num_rows=0;
Spool off;

After the run is completed, the allocate.sql is executed again in the command window, then the EXP statement can be used, so that the empty table can be exported.
