Re: [castor-dev] KeyGen: PK of Object just created

Title: RE: [castor-dev] KeyGen: PK of Object just created

So if my architecture is EJBs and my container handles all transactions then I basically can't get the identity value back on a create().

 

Is that assumption correct?

Last time I used it, the identity is not set until you commit the transaction, which is an almighty pain :)

Margaret,

The key is generated inside the create method not by the client which calls
create. Castor generates the key using @@identity at the database for SQL
Server.
http://castor.exolab.org/key-generator.html#IDENTITY-key-generator

I did try printing the primary key but it does not seem to work
db.create(newProduct);
System.out.println("The PK Returned is " +
((Integer)db.getIdentity(newProduct)).intValue() );

Ayush,
Isn't the value available in the object you just created? I haven't used key
generators yet, but that would seem logical to me...

This might be a trivial question but since create(newProduct) does not
return anything, how do I know the primary key of the row which was just
inserted into Product table?

I have a class Product, having productId (IDENTITY Keygen) as its identity.
