() { return DataObjectUtils.intPKForObject(this); } There are similar methods for when primary key is not an integer value. Cheers Cordialement, Pierre Lavignotte Ingénieur Conception & Développement http://pierre.lavignotte.googlepages.com On Mon, Feb 2, 2009 at 2:14 PM, Νίκος Παρά

Re: How to create Meaningful Primary Keys?

Hi Nikos, If you need PK for all your tables, then maybe you need to generate them. But if you only need to use them for a couple tables then you should look at DataObjectUtils class. Cheers, Pierre Cordialement, Pierre Lavignotte Ingénieur Conception & Développement

Re: Cayenne 101

e the list can be in memory. I know it's not logical but I'm quite sure I allready encontered this case. I use Cayenne 2.0.4 so Cayenne 3.0 can differ in some points. Pierre Cordialement, Pierre Lavignotte Ingénieur Conception & Développement http://pierre.lavignotte.googlepages.com

How to prevent Cayenne from fetching BLOB fields ?

Hello, I use Apache Cayenne for a while now with no problem, but I went into a new issue today. I have an Oracle data table containing 2 BLOB fields. When I get the rows from this table, Cayenne also fetches the BLOB data, so the query is very long, or I get a time out exception. I tryed :
