It looks as though you are relying on implicit type casting to compare a string literal with a numeric column. Not a reliable solution:

orclz>
orclz> select * from scott.emp where empno='1234';

no rows selected

orclz> select * from scott.emp where empno='A1234';
select * from scott.emp where empno='A1234'
                                    *
ERROR at line 1:
ORA-01722: invalid number
