how to remove ssh warning in shell script

Question

I'm trying to execute a shell script that connects to other machine by ssh and execute a sql command. It works but always shows me warning like:

"stty: tcgetattr: Not a typewriter"

My shell script is like these:

... ssh -q -T -T $connection <<ENDSSH 
sqlplus -s "user/pass@con" <<EOF
set heading off
select * from ...
EOF
ENDSSH

How could I remove it? Thanks

Run the script with TTY:

... ssh -q -tt $connection <<ENDSSH 
sqlplus -s "user/pass@con" <<EOF
set heading off
select * from ...
EOF
ENDSSH

(note the -T replaced with -tt)
