Missing inverseJoinColumn at ManyToMany relations with composite keys
---------------------------------------------------------------------
Key: HBX-1093
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1093
Project: Hibernate Tools
Issue Type: Bug
Components: hbm2java
Affects Versions: 3.2.2, 3.2LATER
Environment: Hibernate Tools version 3.2.2.Beta1 and 3.2.4.CR1-N200810300202, Oracle Database
Reporter: Nils Kelleter
Using the hbm2java tool for reverse engineering of database tables, the following problem exists:
At ManyToMany relations with composite keys an inverseJoinColumn is missing.
Wrong code:
@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(name = "ET_MANY_TO_MANY_COMP_MAPPING",
joinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP1_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP11_ID", nullable = false, updatable = false) },
inverseJoinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP2_ID", nullable = false, updatable = false) })
public Set<EtManyToManyComp2> getEtManyToManyComp2s() {
return this.etManyToManyComp2s;
}
@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(name = "ET_MANY_TO_MANY_COMP_MAPPING",
joinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP2_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP22_ID", nullable = false, updatable = false) },
inverseJoinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP1_ID", nullable = false, updatable = false) })
public Set<EtManyToManyComp1> getEtManyToManyComp1s() {
return this.etManyToManyComp1s;
}
Correct code:
@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(name = "ET_MANY_TO_MANY_COMP_MAPPING",
joinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP1_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP11_ID", nullable = false, updatable = false) },
inverseJoinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP2_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP22_ID", nullable = false, updatable = false) })
public Set<EtManyToManyComp2> getEtManyToManyComp2s() {
return this.etManyToManyComp2s;
}
@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(name = "ET_MANY_TO_MANY_COMP_MAPPING",
joinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP2_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP22_ID", nullable = false, updatable = false) },
inverseJoinColumns = {
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP1_ID", nullable = false, updatable = false),
@JoinColumn(name = "FK_ET_MANY_TO_MANY_COMP11_ID", nullable = false, updatable = false) })
public Set<EtManyToManyComp1> getEtManyToManyComp1s() {
return this.etManyToManyComp1s;
}
For reproducing this, you can use the following Oracle SQL scripts:
CREATE TABLE ET_MANY_TO_MANY_COMP1 (
ET_MANY_TO_MANY_COMP1_ID NUMBER,
ET_MANY_TO_MANY_COMP11_ID NUMBER,
FIELD VARCHAR2(10),
PRIMARY KEY (ET_MANY_TO_MANY_COMP1_ID, ET_MANY_TO_MANY_COMP11_ID)
);
CREATE TABLE ET_MANY_TO_MANY_COMP2 (
ET_MANY_TO_MANY_COMP2_ID NUMBER,
ET_MANY_TO_MANY_COMP22_ID NUMBER,
FIELD VARCHAR2(10),
PRIMARY KEY (ET_MANY_TO_MANY_COMP2_ID, ET_MANY_TO_MANY_COMP22_ID)
);
CREATE TABLE ET_MANY_TO_MANY_COMP_MAPPING (
FK_ET_MANY_TO_MANY_COMP1_ID NUMBER,
FK_ET_MANY_TO_MANY_COMP11_ID NUMBER,
FK_ET_MANY_TO_MANY_COMP2_ID NUMBER,
FK_ET_MANY_TO_MANY_COMP22_ID NUMBER,
FOREIGN KEY (FK_ET_MANY_TO_MANY_COMP1_ID,FK_ET_MANY_TO_MANY_COMP11_ID)
REFERENCES ET_MANY_TO_MANY_COMP1(ET_MANY_TO_MANY_COMP1_ID,ET_MANY_TO_MANY_COMP11_ID),
FOREIGN KEY (FK_ET_MANY_TO_MANY_COMP2_ID, FK_ET_MANY_TO_MANY_COMP22_ID)
REFERENCES ET_MANY_TO_MANY_COMP2(ET_MANY_TO_MANY_COMP2_ID, ET_MANY_TO_MANY_COMP22_ID),
PRIMARY KEY (FK_ET_MANY_TO_MANY_COMP1_ID,FK_ET_MANY_TO_MANY_COMP11_ID,FK_ET_MANY_TO_MANY_COMP2_ID,FK_ET_MANY_TO_MANY_COMP22_ID)
);

Project: Hibernate Tools
Issue Type: Bug
Affects Versions: 3.2.4 Beta1
Environment: configuration:
Hibernate Tools version: HibernateTools-3.2.4.CR2-R200901280154
Hibernate version: hibernate-3.2.6.ga.zip
Database: Sybase SQL Anywhere 10.0.1.3415

Code Generation Configuration:
Use Java 5 syntax and generate EJB3 annotations switched on.

Reporter: Christian Meyer
Hello,
I have a problem reverse engineering domain code from a sybase anywhere 10 database.
For every table with composite primary key i get the following exception:
org.hibernate.cfg.JDBCBinderException: Duplicate names found for primarykey.
Her is one example:
create table DCALLS
(
AES timestamp default timestamp,
APPLID char(8) not null,
DIALOG integer not null,
COUNTER integer,
constraint PK_DCALLS primary key (APPLID, DIALOG)
);
For downloading developer edition of sybase anywhere version 10 follow the link: http://marketing.ianywhere.com/forms/SQLAny10DevEditionCDReigster
I used a Hibernate dialect from the sybase homepage: http://www.sybase.de/detail?id=1057826
org.hibernate.cfg.JDBCBinderException: Duplicate names found for primarykey.
Existing name: APPLID JDBC name: DIALOG on table org.hibernate.mapping.Table(sybase10.DCALLS)
Duplicate names found for primarykey. Existing name: APPLID JDBC name: DIALOG on table org.hibernate.mapping.Table(sybase10.DCALLS)
all Tables with single key are fine.

When I run the reverse Engineering Tool to generate my classes, one of these classes does not have the correct manytomany annotation defined correctly:
In the example below, the I have User, User_Role and Role
The User classgets generated correctly:
User.java ...
@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "user_role", catalog = "exms", joinColumns = { @JoinColumn(name = "userID", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "roleID", nullable = false, updatable = false) })
public Set<Role> getRoles() {
return this.roles;
}
but Role.java class isn't correct:
@ManyToMany(fetch = FetchType.LAZY, mappedBy = "roles")
public Set<User> getUsers() {
return this.users;
}
Where is the @JoinTable in Role.java?
DROP TABLE IF EXISTS `exms`.`Role` ;
CREATE TABLE IF NOT EXISTS `exms`.`Role` (
`roleID` INT NOT NULL AUTO_INCREMENT ,
`roleName` VARCHAR(45) NOT NULL ,

unnecessary update when merge managed entity

If the entity in em.merge(entity) is managed entity, the merge operation should be ignored. However it issues a update statement in the test case even if there is no changes.
In the test case, Parent entity has a list of Image entity with Many-To-Many relation. em.merge() somehow marks the list as dirty, which causes the update statement.
The following is trace log of the test case.
