eager-load-group and primary key?

[erikture]

Hello!

I am trying to get better performance in my system using load-groups.

I have a CMP bean that I fetch from the database using the method findByName(String name). Name is just an attribute in the bean. This finder returns a local object. Then when I user the getId() method (the primary key) on it all attributes in the lazy-load group is loaded. As far as I know you can not specify the primary key field to be part of a eager-load-group.

How do I get the primary key value without loading the rest of my attributes?

I did forget one thing!

I am also in some cases reaching the CMP bean throw a relation from another bean. The code looks like this.

bean.getOtherBean().getId().

All attributes in otherBean is loaded.

The PK is always 'eager-loaded' - it's the identity used to select the record.

If you just want the PK then you can use getPrimaryKey() on the interface itself and avoid loading the bean at all.
