Re: [JBoss-user] newbie persistence question
Finders can return a single remote interface or a Collection of remote interfaces: your example would return a Collection, as does findAll. david jencks On 2001.09.30 21:39:07 -0400 Frank Morton wrote: > I realize this is probably a really dumb question, but I'm > just getting into the different persistence models. > > I understand CMP and how it could be used nicely > for something like users of a system.

[JBoss-user] newbie persistence question
I realize this is probably a really dumb question, but I'm just getting into the different persistence models. I understand CMP and how it could be used nicely for something like users of a system. But what if I want to do a simple query that returns multiple results, like say all users that live in texas? It seems with what I have studied so far that CMP works great for things that have a unique id that are normally retrieved one at a time, but once you go beyond that, you have to start using BMP. So, with a query as simple as: select * from userlist where state='TX'; you'd have to use BMP. Is that right?
