Note Mapper returns null

@Select("SELECT * FROM url WHERE code = -sharp{code}")
    Url findByCode(@Param("code") String code);
    
    
Url url1 = urlMapper.findByCode("fuck");

returns null all select queries are, it"s strange that I"ve tried to set field names and so on. The SQL executed by
is normal.
