I am unable to define a foreign key with the following three tables. I am unable to find the error having searched the documentation and tried several variations.
Note that I created the first two tables with and without the index clause in the table ddl with no difference in outcome. The three tables and the first foreign key, person_person_address_FK1, create properly. The second foreign key, address_person_address_FK1, causes the error. Please help. create table person ( person_id int unsigned not null auto_increment, constraint person_pk primary key (person_id), index(person_id)); create table address ( address_id int unsigned not null auto_increment, constraint address_pk primary key (address_id), index(address_id)); create table person_address ( person_id int unsigned not null, address_id int unsigned not null); -- This statement works. alter table person_address add constraint person_person_address_FK1 foreign key (person_id) references person (person_id); -- This statement fails. alter table person_address add constraint address_person_address_FK1 foreign key (address_id) references address (address_id); Replies may be sent to [EMAIL PROTECTED] Thank you!
