利用SQL *Plus复制遗留的Oracle数据表

COPY FROM user/pw@dblink TO user/pw@dblink CREATE tablename -
USING select-statement;

SQL> CREATE TABLE my_views AS  2     
SELECT * FROM user_views;   
SELECT * FROM user_views          *

SQL> SET LONG 100000
SQL> COPY FROM hr/hr@orcl CREATE my_views -
>USING select * from user_views;

Array fetch/bind size is 15. 
(arraysize is 15)Will commit
