I have a DB table created in MySQL using the following SQL
create table apackage
(
apackageID integer NOT NULL AUTO_INCREMENT,
PRIMARY KEY(apackageID),
userID_fk integer,
FOREIGN KEY (userID_fk) REFERENCES user(userID),
status integer ZEROFILL,
description varchar(50),
notefield mediumtext,
basepackageID_fk integer,
addonpackageID_fk integer,
index userID_index (userid_fk),
index bpID_index (basepackageID_fk),
index aopID_index (addonpackageID_fk)
) ENGINE=INNODB;When I use the create Hibernate Mapping function I get a duplicate
entry for the addonpackageID_fk (called addonpackage1, why the 1
I also don’t know) in both the hbm.xml and .java file.See below, Any ideas?
— .hbm.xml file–<?xml version=”1.0″?>

Paul –
I need more info to be able to help you. SPecifically, what version of mysql are you using and what JDBC connector (and version). Also, the many-to-one mappings are only created when there is a foreign key mapping present – I only see the definition for userID_fk. Where is the FK DDL for the other mappings (including addonpackage)?

Ok MySQL version is 5.0.1-alpha-nt-max
JDBC driver is jdbc2_0-stdext.jarhere is the file I use to create the DB. My DB design is rustry so wouldn’t
doubt if I have an issue in my design causing issues with the hibernate module.Create table user
