Copying Long Raw Column Data to another table

Question

hi everyone,
i am trying to Copy Long Raw Column Data to another table in the same schema. this is the situation
Table A (col1 number,col2 long raw) with 100 records
Table B (col1 number,col2 long raw) with 0 records
now i want to copy col2 of the table A into the column 2 of the table B. but long raw data cant be retrieved in a select statement so is there any specific procedure that will copy long raw data or there is any simple way.
i will be really grateful for anybody's help.
thanx

Dust off that old SQL*PLUS command "COPY" ...
create table tablea (col1 number,col2 long raw)
insert into tablea values (1, testrawio.chartoraw('this is line one'));
insert into tablea values (2, testrawio.chartoraw('this is line two'));
insert into tablea values (3, testrawio.chartoraw('this is line three'));
create table tableb (col1 number,col2 long raw)
copy from scott/tiger@larry insert tableb (col1, col2) using select col1, col2 from tablea
Array fetch/bind size is 15. (arraysize is 15)
Will commit when done. (copycommit is 0)
Maximum long size is 80. (long is 80)
   3 rows selected from scott@tiger.
   3 rows inserted into TABLEB.
   3 rows committed into TABLEB at DEFAULT HOST connection.
SQL>Now to prove it has worked :
begin
   for lr in (select col1, col2 from tableb)
   loop
      dbms_output.put_line('col1 = '||lr.col1||
                           ' and col2 contains long raw equivalent of '||testrawio.rawtochar(lr.col2));
   end loop;
end;
col1 = 1 and col2 contains long raw equivalent of this is line one
col1 = 2 and col2 contains long raw equivalent of this is line two
col1 = 3 and col2 contains long raw equivalent of this is line three
PL/SQL procedure successfully completed.
SQL> Note : In order to load some test data and prove the method works I made use of a package called "testrawio" located at http://www.classicity.com/oracle/htdocs/forums/ClsyForumID125/7.html
