mysql - 绕过错误代码：1442。无法更新调用此存储函数/触发器的语句所使用的表

Question

我希望执行以下操作，

drop database ABC;
create database ABC;
use ABC;

create table head (
head_id int primary key auto_increment,
head_name varchar(55)
);

create table table1 (
t1_id int primary key,
t1_name varchar(55),
foreign key (t1_id) references head(head_id)
);


insert into head(head_name) values ('table1');
insert into table1(t1_id,t1_name) select max(head_id),'HI' from head;


select * from head;
select * from table1;

但我希望使用触发器，因为我必须这样做很长一段时间，所以我编写了以下代码，但由于提到的错误它不起作用。

drop database ABC;
create database ABC;
use ABC;

create table head (
head_id int primary key auto_increment,
head_name varchar(55)
);

create table table1 (
t1_id int primary key,
t1_name varchar(55),
foreign key (t1_id) references head(head_id)
);

delimiter $$
CREATE
    TRIGGER `t1` BEFORE INSERT
    ON `table1`
    FOR EACH ROW BEGIN
        insert into head (head_name) values ('table1');
    END
$$
delimiter ;

insert into table1(t1_id,t1_name) select max(head_id),'HI' from head;

select * from head;
select * from table1;

上面的触发器给了我错误，

Error Code: 1442. Can't update table 'head' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

任何帮助！
