You are selecting a NULL into a host variable that does not have an associated indicator variable. This is not in compliance with the ANSI/ISO standards, and was changed beginning with Oracle7. If possible, rewrite your program using indicator variables, and use indicators in future development. Indicator variables are described “Indicator Variables”. Alternatively, if precompiling with MODE=ORACLE and DBMS=V7 or V8, specify UNSAFE_NULL=YES on the command line (see “UNSAFE_NULL” for more information) to disable the ORA-01405 message.
