How to find distinct rows with field in list using JPA and Spring?

@Query("SELECT DISTINCT name FROM people WHERE name NOT IN (:names)")
List<String> findNonReferencedNames(@Param("names") List<String> names);

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

Have you tried rewording your query like this?

@Query("SELECT DISTINCT p.name FROM People p WHERE p.name NOT IN ?1")
List<String> findNonReferencedNames(List<String> names);

Note, I'm assuming your entity class is named People, and not people.
