MySQL Forums :: Newbie :: foreign key constraint fails

OK, is that what you need?

This works:

INSERT INTO `RHSSP`.`CmeList` (
`CeID` ,
`CeDateTime` ,
`CeEvCat` ,
`CeHours` ,
`CePresenter` ,
`CeDescript` ,
`CeLoc` ,
`CeDocName` ,
`CeDocSize` ,
`CeDocType`
)
VALUES (
NULL , '2012-03-30', '114', '2', 'jack', 'talk', 'Auditorium', NULL , NULL , NULL
);


This doesn't:

INSERT INTO `RHSSP`.`CmeList` (

`CeID` ,
`CeDateTime` ,
`CeEvCat` ,
`CeHours` ,
`CePresenter` ,
`CeDescript` ,
`CeLoc` ,
`CeDocName` ,
`CeDocSize` ,
`CeDocType`
)
VALUES (
NULL , '2012-03-30', '115', '2', 'jack', 'talk', 'Auditorium', NULL , NULL , NULL
)
MySQL said:

#1452 - Cannot add or update a child row: a foreign key constraint fails (`rhssp`.`cmelist`, CONSTRAINT `cmelist_ibfk_1` FOREIGN KEY (`CeEvCat`) REFERENCES `lookup` (`LuID`))


As long as CeEvCat (constrained to Lookup.LuID) is <115 we get the first behavior. Anything above 115 we fail. Here are the table structures:

CREATE TABLE Lookup (
LuID INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
LuCat VARCHAR(50),
LuVal VARCHAR(50),
INDEX (LuID)
)ENGINE=InnoDB DEFAULT CHARSET=latin1;

CREATE TABLE CmeList (
CeID INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
CeDateTime DATETIME NOT NULL,
CeEvCat INT UNSIGNED NOT NULL,
CeHours DECIMAL(3,2) UNSIGNED NOT NULL,
CePresenter TEXT NOT NULL,
CeDescription TEXT NOT NULL,
CeLoc TEXT NOT NULL,
CeDoc BLOB,
INDEX (CeEvCat, CeID),
FOREIGN KEY (CeEvCat) REFERENCES Lookup(LuID)
) ENGINE=InnoDB;

Thanks for helping!
