问题
I have an entity that has few fields. One of them is city name. Now I want to get list of all distinct cities from that table. How can I archive that. I tried using DISTINCT keyword, but it doesn't work.
I'm using Hibernate as JPA provider but I would like to get it in pure JPA Query.

Have you tried:
SELECT DISTINCT t.city FROM MyTable t
