Re: EJB CMP suggestion
Hello Jen, To find out how to be able to specify joins or any SQL in custom finders, read: http://www.orionserver.com/docs/orion-ejb-jar.xml.html Search for query and look at the partial attribute. What you want is already possible, without changing the code of your beans. Regards, Karl Avedal Jen Hsien Huang wrote: EJB CMP feature is fantasy. But it's use less because I cant do a simple joint on it, so I wonder the benifit of CMP is just a dream. for example I have two EJB , Company and Product, a Product can use Company as it CMP field , but if I want a finder method search the Product by the Company name, that's impossible. So why not define a CMP finder syntax can do a simple joint ? for example public Collection findByCompanyName(String value) throws RemoteException, FinderException; public static final String findByCompanyName_query = "$company.name LIKE $1"; this will generate a SQL call that joint tables of Product and Company. ex "SELECT * from Product , Company where Company.id = Product.company and Company.name LIKE ? " I think this will make CMP more useful.
RE: EJB CMP suggestion
How about having your Product company finder query to be "SELECT * FROM Product WHERE Product.company = (SELECT Company.id FROM Company WHERE Company.name LIKE ?" I understand that this query may not be identical to the query you provided. But my point is it is possible.
