How about the NULL's? Usually you have to code for all three possibilities

     ((O.WARNING_CODE_EXPIRATION_1 <> I.WARNING_CODE_EXPIRATION_1)
     OR (O.WARNING_CODE_EXPIRATION_1 IS NULL AND I.WARNING_CODE_EXPIRATION_1
     IS NOT NULL)
     OR (O.WARNING_CODE_EXPIRATION_1 IS NOT NULL AND
     I.WARNING_CODE_EXPIRATION_1 IS NULL)
     )

Regards,

Dave
