sqlplus is showing output on stdout
I have following "set" before running a query:
set serverout off term off echo off newpage 0 space 0 pagesize 0 feed off head off trimspool on;
spool val.dat;
set timing on;
select * from abc
spool off
set echo on newpage 0 space 0 pagesize 0 feed on ;
When I run the script I get the output in val.dat and also on stdout. How can I turn off the output to stdout. I have tried the above options to try to turn it off, but nothing works
