simple sqlplus question

--sql script t1.sql

set hea off;
set echo off;

spool t1_out

select rid
from   &&schema_name..customers
where rid=1;

spool off

----------


And when I ran the above script, I got in my spooled file:


Enter value for schema_name: dev72upd
old   2: from   &&schema_name..customers
new   2: from   dev72upd.customers

         1     


Which sqlplus command should I use in my t1.sql so that I only see "1" (the
last line) in my spooled file?

TIA.

Guang
