Hi Ken,
thank you for your reply. This looks exactly like the thing i have looked for, but i have no idea how to use this?
How do i get a list of Cars with the ERXOrQualifier? Sorry for this question, but i have never done it like this before.
Can you help me?
Thanks,
Daniel

Daniel,
You can use the in method of the ERXKEY like this:
NSArray<Brand> brands = new NSArray<Brand>(new Brand[] {vw, audi, bmw});
Car.BRAND.in(brands);
This still generates an OR qualifier, but it’s prettier.

_______________________________________________Hi Experts,i'm strugeling around with an (i think so) easy problem: What is the right way to make an Qualifier (for a Fetch-Specification in EOModeler) to not search with just one single Object, but with a list of objects:For example this model:1 Car-Brand produces many Cars (e.g. VW procudes Jetta, Golf, Passat, etc.)If i want to search all Cars for "VW" my qualifier looks something like:brand = $carBrand ... (eg. Car.fetchForList(ec, brandVW);)But was is the correct way to search for a list of brands? e.g: What is the correct way to search for all Cars of "VW", "Audi", etc.?I know that it is possible to search something like this:brand = $carBrand1 or brand = $carBrand2, etc. (e.g. Car.fetchForList(ec, brandVW, brandAudi, etc.);).But this is not the best way?Thank you,Daniel
