Question

我有firebird数据库，并创建使用它的java项目。通过使用GenerationTool我生成数据库结构。当我尝试这样的执行语句时，一切正常。

Result<Record1<Integer>> toStations = create.select(STATIONS.STATION_ID).
                    from(STATIONS).
                    where(STATIONS.CITY_ID.equal(create.select(CITIES.CITY_ID).
                            from(CITIES).
                            where(CITIES.CITY_NAME.equal(to)))).fetch();

但是我无法执行存储过程。我有存储过程：

create or alter procedure Find_Schemes (
    FROM_STATION ID not null,
    TO_STATION ID not null)
returns (
    SCHEME_ID ID)
as
begin
  for select SCHEME_ID
      from SCHEMES S
      where PATH_ID = (select PATH_ID
                       from PATHES P
                       where PATH_ID = S.PATH_ID and
                             (select LIST_POS
                              from PATHES_STATIONS
                              where PATH_ID = P.PATH_ID and
                                    STATION_ID = :FROM_STATION) < (select LIST_POS
                                                                   from PATHES_STATIONS
                                                                   where PATH_ID = P.PATH_ID and
                                                                         STATION_ID = :TO_STATION))
      into :SCHEME_ID
  do
  begin
    suspend;
  end
end
^

我试着像这样执行他

Result result = (Result) Routines.findSchemes(7,22);
            System.out.println(result);

但是我有例外而不能将其转换为（结果）;

然后我尝试这样做，但这不起作用因为findSchemes需要String参数，但在我的程序中只有Integer参数：

Result result = create.select(FIND_SCHEMES(7,22));

如何使用JOOQ执行Firebird程序？

通过输入随机命令3小时后就可以了。

Result result = create.selectFrom(Routines.findSchemesWithInfo(7, 22)).fetch();

System.out.println(result);
