ops$tkyte_at_ORA8I.WORLD> select ascii('1') from dual;

ASCII('1')


        49

ops$tkyte_at_ORA8I.WORLD> select ascii('A') from dual;

ASCII('A')


        65

ops$tkyte_at_ORA8I.WORLD> select * from dual where '1' >= 'A';

no rows selected

ops$tkyte_at_ORA8I.WORLD>

ascii '1' is less then ascii 'A' so it won't be returned...
