帶有限制和偏移的彈簧本機查詢

-1

我有一個擴展CrudRepository的接口。這個界面裏面，我有一個方法帶有限制和偏移的彈簧本機查詢

@Query(value = "SELECT * from bonuses where bonuses.user_id=:userId order BY bonuses.time desc limit (' || :limit || ') offset ('|| :offset || ') ", nativeQuery = true) 
    List<Bonuses> findAllByUserId(@Param("userId") Integer userId, @Param("limit") Integer limit, @Param("offset") Integer offset);

但在執行這種方法，我得到以下錯誤：

的原因是什麼？我檢查了userId，限制和偏移從不爲空。

請嘗試以下操作

@Query(value = "SELECT * from bonuses where user_id=:userId order BY 
     time desc limit (' || :limit || ') offset ('|| :offset || ')", 
     nativeQuery = true) 
List<Bonuses> findAllByUserId(@Param("userId") Integer userId, 
@Param("limit") Integer limit, @Param("offset") Integer offset);
