LAzy fetch for specific named queries in a POJO class

[akhil achuthan]

Is it possible to define lazy fetch for specific named queries in an entity POJO. I mean i have a Person table with a one-to-many mapping defined on to other tables. Eg: For my UI which lists only the names of all the Person rows, I just need the name of all the person entries and feel that I need not fetch the entire column contents of the table along with the data of whatever mapped children tables it has. I mean all my named queries that I have defined in my JPA Pojo should return me the entire object with child values as well, except this specific query alone.

Thanks in advance

I would recommend making the relationships LAZY always, then using a JOIN FETCH to fetch them eagerly when required.
In general LAZY allows the relationship to only be fetched when required.

You can also execute a query that only selects the names, if all you want is the names.
i.e.

Select p.name from Person p

If you are using EclipseLink there is also support for fetch groups, that allow you to specify through query hints exactly what you wish to be fetched in the object.
