Set command to eliminate strange characters

Question

I have a very simple query
set heading off;
SPOOL on;
SELECT GENERAL.GJBPSEQ.NEXTVAL from dual;
COMMIT;
EXIT;
create a file
oneup.dat
I need to read this file in s shl script
sqlplus -s  ${ID}/${PW} ${AT_SIGN}${SCRIPT_PATH}${SCRIPT_NAME} > oneup.dat
read oneup < oneup.dat
It seems that the file is has strange characters, it is suppose a numeric value (from the seq,GJBPSEQ)
I know it is a command set that I can use in the sql query to make sure that I will bring just a numeric value with not strange characters..

Answer 1

I'd turn off more settings if I were you:
set heading off;
set timing off
set echo off
set feedback off
set pagesize 0
SPOOL ./oneup.dat;
SELECT GENERAL.GJBPSEQ.NEXTVAL from dual;
spool off
EXIT;
After running it, my spool file looks simply:
unix > more oneup.dat
         2
so now in unix, you can cram it into a variable easy enough:
unix > read oneup < oneup.dat
unix > echo $oneup
2
