Hi,
I am using JBoss-4.0.3.
Shortly my scenarion:
Table definitions:
----------------------------
-- Categories
----------------------------
id integer not null
name varchar(50) not null --> books:category
--------------------------------
-- Books
--------------------------------
id integer not null
title varchar(50) not null
category integer not null
The CMP Entity beans:
/* Categories */
...
/**
* @ejb.interface-method
*
* @ejb.relation name="CategoriesBooks"
* role-name="CategoryHasBooks"
* target-ejb="BooksBean"
* target-role-name="CategoryOfBook"
*
* @jboss.relation fk-column="category"
* related-pk-field="id"
*
*/
public abstract Collection getBooks();
/** @ejb.interface-method */
public abstract void setBooks(Collection c);
/* Books */
...
/**
* @ejb.interface-method
*
* @ejb.relation name="CategoriesBooks"
* role-name="CategoryOfBook"
* target-ejb="CategoriesBean"
* target-role-name="CategoryHasBooks"
* target-multiple="yes"
*
* @jboss.relation fk-column="id"
* related-pk-field="id"
*
*/
public abstract Collection getCategories();
/** @ejb.interface-method */
public abstract void setCategories(Collection c);
The output looks like this:
[CategoriesSFBean] ejbCreate
[CategoriesBean#findByPrimaryKey] Executing SQL: SELECT t0_CategoriesBean.id FROM categories t0_CategoriesBean WHERE t0_CategoriesBean.id=?
[CategoriesBean] Executing SQL: SELECT name FROM categories WHERE (id=?)
[CategoriesBean] load relation SQL: SELECT category FROM categoriesbean_books_booksbean_categories WHERE (id=?)
But my goal is to see all the books that belong to one (specified) category. What should I modify to have something like this:
SELECT id, title, category FROM categoriesbean_books_booksbean_categories WHERE (category=?)
?
