Can spool a file with just sql result?

Question

Hi, I am trying to using sql to generate sql script and then run it, it's like this:
set heading off
set feedback off
spool gt.sql
select 'grant select on '||table_name||';' from dba_tables where owner='ABC';
spool off
@gt.sql
The script generated looks like this:
SQL >select 'grant select on '||table_name||' to ABC';' from dba_tables where owner='ABC';
grant select on EMP to ABC;
SQL> spool off
IS there an sqlplus command that will not make the two sql commands show? so I can run the gt.sql right away instead of having to manually remove those two SQL> XXX before I can run the script.
Thanks a lot.

Answer 1

set echo off
also, and more importantly, you need to put all of into a single sql script. ex:
gen_gt.sql
set echo off
set heading off
set feedback off
spool gt.sql
select 'grant select on '||table_name||';' from dba_tables where owner='ABC';
spool off
[eof]
SQL> @gen_gt
SQL> @gt
