MySQL While 循环用增量值填充表，其中没有自动增量选项

Question

我尝试用目前的增量值填充 MySQL 表。稍后可能会发生变化，为什么自动增量在这里不是解决方案。 我正在 phpMyAdmin 的 SWL 控制台中工作

只有settingsOperationMixerId启用了自动增量

我尝试做一个循环:

DELIMITER ;
CREATE PROCEDURE fill()
BEGIN
    DECLARE v1 INT DEFAULT 1;
    DECLARE b INT DEFAULT 1; #counting upwards
    DECLARE c INT DEFAULT 1; #only 1 mixer
    DECLARE d INT DEFAULT 1; #product from 1-6


     WHILE v1 < 64 DO


        INSERT INTO `settingsoperationmixer`(`settingsOperationMixerId`,
        `settingsOperationId`, `mixerId`, `productId`) VALUES (NULL,b,c,d);

        IF d < 6 THEN SET d = d + 1;
        ELSE SET d = 1;
        END IF;

        SET b = b + 1;
        SET v1 = v1 + 1;
    END WHILE;
END;
DELIMITER ;

这应该循环 63 次，而 settingsOperationId 将从 1-63 递增，productId 应该从 1-6，然后从 1 重新开始

并收到此错误消息:

Error

SQL query:

CREATE PROCEDURE fill()
BEGIN
DECLARE v1 INT DEFAULT 1

有更正

drop procedure if exists p;
delimiter $$
CREATE PROCEDURE p()
BEGIN DECLARE v1 INT DEFAULT 1; 
DECLARE a INT DEFAULT 1; #autoIncrement 
DECLARE b INT DEFAULT 1; #counting upwards 
DECLARE c INT DEFAULT 1; #only 1 mixer 
DECLARE d INT DEFAULT 1; #product from 1-6

 WHILE v1 < 64 DO
    INSERT INTO `settingsoperationmixer`(`settingsOperationMixerId`,`settingsOperationId`, `mixerId`, `productId`)  VALUES (a,b,c,d);
    IF d < 6 THEN 
        SET d = d + 1;
     ELSE 
        SET d = 1;
     end if;

    SET b = b + 1;
    SET v1 = v1 + 1;
END WHILE;
END $$
delimiter ;

如果您想允许应用 auto_increment，则不要将其包含在插入列表中

drop procedure if exists p;
delimiter $$
CREATE PROCEDURE p()
BEGIN DECLARE v1 INT DEFAULT 1; 
DECLARE a INT DEFAULT 1; #autoIncrement 
DECLARE b INT DEFAULT 1; #counting upwards 
DECLARE c INT DEFAULT 1; #only 1 mixer 
DECLARE d INT DEFAULT 1; #product from 1-6

 WHILE v1 < 10 DO
    INSERT INTO `settingsoperationmixer`(`settingsOperationId`, `mixerId`, `productId`)  VALUES (b,c,d);
    IF d < 6 THEN 
        SET d = d + 1;
     ELSE 
        SET d = 1;
     end if;

    SET b = b + 1;
    SET v1 = v1 + 1;
END WHILE;
END $$
delimiter ;
drop table if exists `settingsoperationmixer`;
create table `settingsoperationmixer`
(`settingsOperationMixerId` int auto_increment primary key ,`settingsOperationId` int, `mixerId` int, `productId` int)
;
call p();
