Stored procedures 用于检索表缺少的自动增量ID的MySQL过程？

我创建了一个过程来从表中查找缺少的id，但它不会检索任何结果，下面是该过程

DELIMITER ||
DROP PROCEDURE IF EXISTS proc_rpt ||
CREATE PROCEDURE proc_rpt()
BEGIN 
SET @minID = (SELECT MIN(`id`) FROM `tbl_film` WHERE `user_id`=13);
SET @maxID = (SELECT MAX(`id`) FROM `tbl_film` WHERE `user_id`=13);
REPEAT 
    SET @tableID = (SELECT `id` FROM `tbl_film` WHERE `id` = @minID);
    IF (@tableID IS NULL) THEN
        INSERT INTO temp_missing(`missing_id`) VALUES (@tableID);
    END IF;
    SET @minID = @minID + 1; 
UNTIL (@minID <= @maxID)
END REPEAT;  // earlier I was missing this line which was giving error in Procedure.
END; ||

但是没有关于tbl_缺失的结果，而我可以看到在

tbl_film

中有许多

film_id

的缺失值。有人能告诉我我做错了什么吗？

试试这段代码

DELIMITER ||
    DROP PROCEDURE IF EXISTS proc_rpt ||
    CREATE PROCEDURE proc_rpt()
    BEGIN 
    DECLARE maxId int;
    DECLARE minId int;
    DECLARE curId int;
        SELECT MIN(`id`) INTO maxId FROM `tbl_film` WHERE `user_id`=13;
        SELECT MAX(`id`) INTO minId FROM  `tbl_film` WHERE `user_id`=13;
    REPEAT 
        SELECT `id` INTO curId FROM `tbl_film` WHERE `id` = @minID);
        IF (curId IS NULL) THEN
            INSERT INTO temp_missing(`missing_id`) VALUES (curId);
        END IF;
        SET minId = minId + 1; 
    UNTIL (minId <= maxId)
    END REPEAT;  // earlier I was missing this line which was giving error in Procedure.
    END; ||

如果存在过程，则删除过程||
创建过程proc_rpt（）
开始
声明maxId int；
声明minId int；
声明curId int；
从'tbl_film'中选择MIN（'id'）进入maxId，其中'user_id`=13；
从'tbl_film'中选择MAX（'id'）进入minId，其中'user_id`=13；
重复
从'tbl_film'中选择'id'进入curId，其中'id'=@minID）；
如果（curId为NULL），则
插入temp_missing（`missing_id`）值（curId）；
如果结束；
设置minId=minId+1；
直到（分钟）
