Hi, I've managed to break referential integrity (reaching a state which is not correct) the following way. I am using the latest H2, I've managed to reproduce this with H2 Console, connecting to it with the browser client and a separate JDBC client. These are my tables:
CREATE TABLE "PUBLIC"."core_driver" ( id integer PRIMARY KEY NOT NULL, ); and CREATE TABLE "PUBLIC"."core_jobstatus" ( id integer PRIMARY KEY NOT NULL, driver_id integer NOT NULL, ); ALTER TABLE "PUBLIC"."core_jobstatus" ADD CONSTRAINT core_jobstatus_driver_id_179f91138d7c8c95_fk_core_driver_id FOREIGN KEY (driver_id) REFERENCES "PUBLIC"."core_driver"(id); Checking that I can't violate the constraints by default: insert into "core_jobstatus" values(1, 1); -> Throws exception, all good So let's break it then. 1. Insert data: insert into "core_driver" values(1); 2. In session 1(auto-commit off): begin transaction; insert into "core_jobstatus" values(1, 1); 3. In session 2: delete from "core_driver"; 4. In session 1: commit No exception. Now we are in a situation where there is a record in the core_jobstatus which references to a record in the driver table which does not exists in the driver table. Basically the same situation which I proved in the beginning that it violates the constraint. Is this a bug or what am I doing wrong/how can I work around it?
