如何利用SQL * Plus复制遗留的Oracle数据表

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

ERROR at line 2:

ORA-00997: illegal use of LONG datatype 







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 when done. (copycommit is 0)

Maximum long size is 100000. (long is 100000)

Table MY_VIEWS created.


   1 rows selected from hr@orcl.
   1 rows inserted into MY_VIEWS.
   1 rows committed into MY_VIEWS at DEFAULT HOST connection.


SQL> descmy_views;
