hur man anropar orakelfunktion i mybatis

I Java

void getNo(Map<String,Object> mymap);

I Mapper.xml-filen

    <select id="getNo" resultType="String" parameterType="map" statementType="CALLABLE">
     #{retval, mode=OUT, jdbcType=VARCHAR}  = CALL pc_sys.f_get_no
     (
      #{notyp, mode=IN, jdbcType=VARCHAR},
     #{ymdDate, mode=IN, jdbcType=DATE}
     );
end;
 </select>

Med den här koden löste jag mitt problem.
