Re: WHENEVER SQLERROR EXIT SQL.SQLCODE||SQLERRM & Relate ORA-ERRNO
&SQLCODE

Replies:
SQL*Plus is probably passing 942 out as the return code. However, unix can handle values from 0 to 255. Any return code in excess of 255 is returned as the modulus of
(return_code, 256).

SQL> select mod(942,256) from dual;

MOD(942,256)
------------
     174

This explains why the $? is 174. If you returned codes 174, 430, 686, 1198, 1454, 1710, 1966, etc. $? would be 174 as well. While this limits the value of passing
sql.sqlcode out to the calling script, you could use an exception handler in a pl/sql block to pass out a value that represents likely errors. For example, 0 is
success, 1 is unknown failure, 2 is ORA-00942, etc.
