Subject [jira] Assigned: (OJB-22) Only select pk-columns when the Class is a Proxy
Date Wed, 27 Apr 2005 19:27:25 GMT
     [ http://issues.apache.org/jira/browse/OJB-22?page=all ]

Jakob Braeuchi reassigned OJB-22:

    Assign To: Jakob Braeuchi

> Only select pk-columns when the Class is a Proxy
> ------------------------------------------------
>          Key: OJB-22
>          URL: http://issues.apache.org/jira/browse/OJB-22
>      Project: OJB
>         Type: Improvement
>   Components: PB-API
>     Versions: 1.0.4, 1.1
>     Reporter: Jakob Braeuchi
>     Assignee: Jakob Braeuchi
>      Fix For: 1.1 CVS

> OJB always selects all columns although for proxies only the pk-columns are needed.
> this may leed to memory problems when retrieving many large columns.
> simply selecting pk-columns for proxies does not work, because then we can no longer
materialize a proxy.
> there must be some way to distinguish the initial select from prefetching materializing
