表 hotel_pre_sale_order 有字段 order_no，order_remarks，表hotel_order_remark有字段order_no,remark， 表hotel_pre_sale_order和表hotel_order_remark是一对多，现需要将hotel_pre_sale_order中所对应得表hotel_order_remark 中得字段remark进行拼接 然后导入order_remarks

您可以使用以下SQL查询来将hotel_order_remark表中的remark字段进行拼接，并导入到hotel_pre_sale_order表的order_remarks字段中：

UPDATE hotel_pre_sale_order AS p
SET order_remarks = (
        SELECT GROUP_CONCAT(r.remark SEPARATOR '; ')
        FROM hotel_order_remark AS r
        WHERE r.order_no = p.order_no
        GROUP BY r.order_no
    );

这个查询会将hotel_order_remark表中的remark字段按照order_no进行分组，并使用分号进行拼接。然后将拼接后的结果更新到hotel_pre_sale_order表的order_remarks字段中。请确保两个表之间有正确的关联关系（即order_no字段）。

注意：在执行此查询之前，请务必备份数据以防止意外情况发生。

你可以编写一个存储过程来执行这个查询。下面是一个示例：

CREATE OR REPLACE PROCEDURE get_data AS
BEGIN
  -- 创建临时表来保存结果
  CREATE GLOBAL TEMPORARY TABLE temp_data (
    order_id          NUMBER,
    done_date         DATE,
    cust_id           NUMBER,
    subscriber_ins_id NUMBER,
    access_num        VARCHAR2(100),
    dev_id            NUMBER,
    dev_name          VARCHAR2(100),
    corp_org          VARCHAR2(100),
    company_name      VARCHAR2(100),
    department_code   VARCHAR2(100),
    department_name   VARCHAR2(100),
    remarks           VARCHAR2(100)
  ) ON COMMIT PRESERVE ROWS;

  -- 第一个查询
  INSERT INTO temp_data
  SELECT a.order_id,
         a.done_date,
         a.cust_id,
         a.subscriber_ins_id,
         a.access_num,
         c.dev_id,
         c.dev_name,
         c.corp_org,
         c.company_name,
         c.department_code,
         c.department_name,
         c.remarks
  FROM JOUR1.Om_Subscriber_202301 a
  LEFT JOIN JOUR1.om_order_202301 b
    ON a.order_id = b.order_id
  LEFT JOIN params1.sec_developer c
    ON b.dev_id = c.dev_id;

  -- 后续查询使用UNION ALL连接
  INSERT INTO temp_data
  SELECT a.order_id,
         a.done_date,
         a.cust_id,
         a.subscriber_ins_id,
         a.access_num,
         c.dev_id,
         c.dev_name,
         c.corp_org,
         c.company_name,
         c.department_code,
         c.department_name,
         c.remarks
  FROM JOUR1.Om_Subscriber_202302 a
  LEFT JOIN JOUR1.om_order_202302 b
    ON a.order_id = b.order_id
  LEFT JOIN params1.sec_developer c
    ON b.dev_id = c.dev_id;

  INSERT INTO temp_data
  SELECT a.order_id,
         a.done_date,
         a.cust_id,
         a.subscriber_ins_id,
         a.access_num,
         c.dev_id,
         c.dev_name,
         c.corp_org,
         c.company_name,
         c.department_code,
         c.department_name,
         c.remarks
  FROM JOUR1.Om_Subscriber_202303 a
  LEFT JOIN JOUR1.om_order_202303 b
    ON a.order_id = b.order_id
  LEFT JOIN params1.sec_developer c
    ON b.dev_id = c.dev_id;

  INSERT INTO temp_data
  SELECT a.order_id,
         a.done_date,
         a.cust_id,
         a.subscriber_ins_id,
         a.access_num,
         c.dev_id,
         c.dev_name,
         c.corp_org,
         c.company_name,
         c.department_code,
         c.department_name,
         c.remarks
  FROM JOUR1.Om_Subscriber_202304 a
  LEFT JOIN JOUR1.om_order_202304 b
    ON a.order_id = b.order_id
  LEFT JOIN params1.sec_developer c
    ON b.dev_id = c.dev_id;

  -- 查询结果
  SELECT * FROM temp_data;

  -- 删除临时表
  DROP TABLE temp_data;
END;
/

这个存储过程创建了一个临时表 `temp_data` 来保存查询结果，并将每个查询的结果插入到临时表中。最后，通过查询 `temp_data` 表来获取结果。

请注意，根据你的实际需求和数据库结构，你可能需要修改表和列的定义，以及查询的逻辑。确保在执行存储过程之前，已经创建了所需的表和索引。
