MySQL Workbench：检查2行数据后插入行，循环整个table

Question

我有一个本地 MySQL 服务器实例和大学主题的 MySQL Workbench。

以下 table apjournal 包含工作站的开始和结束时间。

PAID为生产订单，
扫描开始时间时的运行编号

我想在每个工作站之后插入 transportation/buffer 时间的行。

条件：

(r1 := row i, r2 := row i+1)

WHERE PAID_from_r1 = PAID _from_r1 AND ID_from_r2 > ID_from_r1

THEN 
INSERT INTO sys.apjournal (ID, PAID, RID, APID, APID_ST, Startzeit, Endzeit, DurationEvent) 
VALUES (0, PAID_from_r1, RID_from_r1, APID_from_r1, CONCAT('Puffer ',APID_from_r1), Endzeit_from r1, Startzeit_from_r2, 0);

我用运行个数字搜索了 While 循环和过程以及子查询。这是我的尝试。

SELECT
    -
    @ID := CASE
        WHEN @last_ID > data.actual_ID AND @last_PAID = data.acutal_PAID
        THEN @ID + 1            
        ELSE 0
    END AS ID,
    @last_ID := data.ID,
    @last_PAID := data.PAID
    #INSERT INTO sys.apjournal (ID, PAID, RID, APID, APID_ST, Startzeit, Endzeit, DurationEvent) VALUES (3000+i, 1, 1)
    -- //TODO: Weitere Felder ausgeben
FROM
    -- Die Variablen initialisieren
    (SELECT @nr:= 0, @last_ID:=1,@last_PAID:=76) AS vars,
    -- Die Daten sortieren
    (
        SELECT t.*
        FROM sys.apjournal AS t
        ORDER BY PAID
    ) AS data;
    
    
#other strategy ?

drop procedure if exists addPuffer;

DELIMITER //  

CREATE PROCEDURE addPuffer(
StartID INT,
PAID Int
)   
BEGIN
DECLARE i INT DEFAULT 0; 
WHILE (i<2000)  DO
    INSERT INTO sys.apjournal (ID, PAID, RID, APID, APID_ST, Startzeit, Endzeit, DurationEvent) VALUES (3000+i, 1, 1);
    SET i = i+1;
END WHILE;
END;
//  
CALL addPuffer();

构建程序、匹配 2 行的问题对我来说是新的。该过程应遍历整个 table.

我认为这个任务可以用类似于

的一个查询来解决

INSERT INTO sys.apjournal (ID, PAID, RID, APID, APID_ST, Startzeit, Endzeit, DurationEvent) 
SELECT /* DISTINCT */ 0, t1.PAID, t1.RID, t1.APID, CONCAT('Puffer ', t1.APID), t1.Endzeit, t2.Startzeit, 0
FROM apjournal t1
JOIN apjournal t2 ON t1.PAID = t2.PAID 
                 AND t1.ID < t2.ID
             /*  AND another joining conditions */
/* WHERE one more conditions */

但是当前的问题文本不允许定义需要什么额外的加入和过滤条件。
