使用外键从两个h2表中删除

Question

我有一个带有两个带外键的表的h2数据库

CREATE TABLE master (masterId INT PRIMARY KEY, slaveId INT);
CREATE TABLE slave (slaveId INT PRIMARY KEY, something INT,
    CONSTRAINT fk FOREIGN KEY (slaveId) REFERENCES master(slaveId));

并需要类似的东西

DELETE master, slave FROM master m JOIN slave s ON m.slaveId = s.slaveId
    WHERE something = 43;

即,从两个表中删除(AFAIK在MySql中工作).因为FOREIGN KEY我不能先从master中删除.当我从奴隶中删除时,我丢失了要从主站删除哪些行的信息.使用ON DELETE CASCADE会有所帮助,但我不希望它每次都自动发生.我应该暂时允许吗？我应该使用临时表还是什么是最佳解决方案？

Answer 1

没有人回答,但实际上是微不足道的:

SET REFERENTIAL_INTEGRITY FALSE;
BEGIN TRANSACTION;
DELETE FROM master WHERE slaveId IN (SELECT slaveId FROM slave WHERE something = 43);
DELETE FROM slave WHERE something = 43;
COMMIT;
SET REFERENTIAL_INTEGRITY TRUE;
