There was a multivalued dependency, so I separated the tables and came up with this: http://stackoverflow.com/questions/22210461/mysql-error-code-1452-foreign-key-constraint CREATE TABLE NAME ( NameID Integer NOT NULL AUTO_INCREMENT, Name varChar(255) NOT NULL, CONSTRAINT NAME_PK PRIMARY KEY(NameID) ); CREATE TABLE PHONE ( NameID Integer NOT NULL, PhoneNumber varChar(15) NOT NULL, NumType varChar(5) NOT NULL, CONSTRAINT PHONE_FK FOREIGN KEY(NameID) REFERENCES NAME(NameID), CONSTRAINT PHONE_PK PRIMARY KEY(NameID) ); But when attempting to add values with this code: INSERT INTO NAME (NameID, Name) VALUES (default, 'John Doe'); INSERT INTO PHONE (NameID, PhoneNumber, NumType) VALUES (default, '706-782-4719', 'Home'); I receive the infamous 1452 error: Error Code: 1452. Cannot add or update a child row: a foreign key constraint fails (`phone_mcneill`.`PHONE`, CONSTRAINT `PHONE_FK` FOREIGN KEY (`NameID`) REFERENCES `NAME` (`NameID`)) I am not entirely sure what this means as I have NameID autoincrementing in the first table. I can't have it auto_increment in the second one as well as it's a foreign key, correct? Thanks in advance for the help. mysql sql database foreign-keys mysql-error-1452 share|improve this question asked Mar 5 '14 at 22:10 Archibald 272215 add a comment| 1 Answ
