在mybatis中该sql语句有什么错误<select id="selectJourneyTempDetailListById" resultMap="JourneyTempDetailDtoResult"> select temp_day, GROUP_CONCAT(activity_id) activity_id, GROUP_CONCAT(address_type_cd) address_type_cd, GROUP_CONCAT(activity_type_cd) activity_type_cd, GROUP_CONCAT(presenter_type_cd) presenter_type_cd, from journey_temp_detail where temp_id = #{id} and is_del = '0' group by temp_day </select>

这个 SQL 语句中的错误是缺少了 `SELECT` 关键字。在 `from` 关键字前面应该加上需要查询的列名，比如 `SELECT temp_day, GROUP_CONCAT(activity_id) activity_id, ...`。修改后的 SQL 语句如下：

<select id="selectJourneyTempDetailListById" resultMap="JourneyTempDetailDtoResult">
  SELECT
    temp_day,
    GROUP_CONCAT(activity_id) activity_id,
    GROUP_CONCAT(address_type_cd) address_type_cd,
    GROUP_CONCAT(activity_type_cd) activity_type_cd,
    GROUP_CONCAT(presenter_type_cd) presenter_type_cd
  FROM journey_temp_detail
  WHERE temp_id = #{id} AND is_del = '0'
  GROUP BY temp_day
</select>

注意，在 `WHERE` 子句中使用的参数 `id` 应该在 Java 代码中传入。
