JPA native query return class

Question

In the JPA, I defined a native sql which will return String,

@NamedNativeQuery(name = \"alert\", 
query = \" select distinct c.accountId from account c \", 
            


        

Answer 1

Seems Hibernate only allows Entity result classes. Obviously not all JPA implementations have this restriction. DataNucleus JPA, for example, allows that query to run fine.
