Hi,

I've seen this topic discussed in a previous thread - but the same conditions don't appear to apply to my problem. I am using mysql 5 and hibernate tools 3.24

I have the following table defined

CREATE TABLE `category` (
`CategoryID` bigint(20) NOT NULL,
`Category` varchar(120) DEFAULT NULL,
`SectionID` bigint(20) DEFAULT NULL,
PRIMARY KEY (`CategoryID`),
KEY `SectionID` (`SectionID`),
CONSTRAINT `category_ibfk_1` FOREIGN KEY (`SectionID`) REFERENCES `section` (`
SectionID`) ON DELETE NO ACTION ON UPDATE NO ACTION)

After running hibernate reengineering tools, table now looks like this

CREATE TABLE `category` (
`CategoryID` bigint(20) NOT NULL,
`Category` varchar(120) DEFAULT NULL,
`SectionID` bigint(20) DEFAULT NULL,
PRIMARY KEY (`CategoryID`),
KEY `SectionID` (`SectionID`),
KEY `FK302BCFEE2FAD9F4` (`SectionID`),
CONSTRAINT `FK302BCFEE2FAD9F4` FOREIGN KEY (`SectionID`) REFERENCES `section`
(`SectionID`),
CONSTRAINT `category_ibfk_1` FOREIGN KEY (`SectionID`) REFERENCES `section` (`
SectionID`) ON DELETE NO ACTION ON UPDATE NO ACTION
)


So Hibernate tools appears to added an extra constraint and an extra key - duplicating the ones already there. If I run it again it will add them again.

Is there anyway I can tell the tool not to generate any extra keys or foreign contraint? or anyway I can define the table such that this won't happen?

Thanks

James Thornley
