Calling sqlplus from unix shell script

Question

Hi All,
I am executing the following code :-
sqlplus -s ${DATABASE_USER} |&
print -p -- 'set feed off pause off pages 0 head off veri off line 500'
print -p -- 'set term off time off serveroutput on size 1000000'
print -p -- "set sqlprompt ''"
print -p -- "SELECT run_command from tmp_run_batch where upper(batch_name) = upper('${PAR_PROGRAM_NAME}');"
read -p RUN_COMMAND
eval print -p -- \""execute dbms_output.put_line(${RUN_COMMAND});"\"
read -p RET_VAL
print -p -- "exit;"
The select stmt given above gives sample output as :-
pack_claims_clas_utils.func_main('$PAR_RUN_DATE','$PAR_RUN_LEVEL','$PAR_EXCLUSIVE_RUN_YN')
And then this package is executed.
The problem that I am facing is how to handle the no_data_found case of the select stmt. . When this case arises then the stmt. "read -p RUN_COMMAND" hangs.
Could you please provide any solution ?
Thanks
Suds

Hi,
Have you tried this:
# if [ -n means String has non-zero length
if [ -n $RUN_COMMAND ]
read -p RUN_COMMAND
fi
