> PK Generation with "meaningful PK"
> ----------------------------------
>
> Key: CAY-1576
> URL: https://issues.apache.org/jira/browse/CAY-1576
> Project: Cayenne
> Issue Type: Question
> Components: Database integration
> Affects Versions: 3.1M1
> Environment: Win7 with PostgreSQL 9
> Reporter: nico
> Labels: features
>
> I have a question about the primary generation.
> I generate all classes with the Cayenne Modeler from the database with
> "meaningful PK" option, because I need the getId()-method from the entity,
> which gives me the Pk from the database.
> I set the Pk Generation Stategy to Database-Generated in all DbEntities,
> because I don't wan't to set the Pk by myself or by Cayenne, but by database.
> Now I have the situation that Cayenne fetch the first PK from DB by calling
> the sequence in Db, then Cayenne increment the ID 20 times (on 20 inserts)
> and send the IDs (PKs) to database, then cayenne call another time the
> sequence for next Pk id and so on.
> But I don't want that cayenne send any generated PK Id to database and only
> let the database generate the Ids. I think this is a result of the
> "meaningful PK" setting.
> Is there any solution to get the database PK Id from a Object Entity (at best
> with getId()-method) without a database call and let the database generate
> the primary keys?
> I hope this is understandable.
> thanks in advance
