I must disagree. You can return a numeric value from 0 to 255 (?) from a
sql*plus session. If you return a number larger than 255,
it is the modulus of value/256.
$ echo $?
0
$ sqlplus "/ as sysdba"
SQL> exit 1
$ echo $?
1
$ sqlplus "/ as sysdba"
SQL> whenever sqlerror exit 1

select * from alskjfajafls

$ sqlplus "/ as sysdba"
