Hi edikus, I think while creating the FK constraint you can specify 3 categories like a) ON DELETE NO ACTION b) ON DELETE CASCADE c) ON DELETE RESTRICT. Defualt is : ON DELETE NO ACTION. So in that case it will remove the ONE and set the fk to null in MANY. In your case you can set that to ON DELETE RESTRICT. Ex: ALTER TABLE MYTABLE ADD CONSTRAINT FK_MANY_ONE FOREIGN KEY (ONE_FK) REFERENCES ONE (ID) ON UPDATE NO ACTION ON DELETE RESTRICT.
