Hi
Does jdo (and therefore jbossdo) support pulling back different subsets of fields on the fly? A jdo defines 10 fields, but you only want 5 of them one time, and 7 the next. Also, say I have two jdos related to each other via a simple n:1 relationship, a to b. Lets say I pull back all of the a’s matching a certain criteria, but I want to quickly get at data inside of each associated b. Does this resolve to 1 query, or is a separate query made each time I access the field in b (e.g. a.getB().attributeOfB). I’m just researching using this now, don’t actually have any code written.
Hope this is clear.
