In IntelliJ IDEA HQL console can be used with pure JPA facets (as well as with Hibernate facets) to run JPAQL and HQL queries. All you need is Hibernate libraries and JDBC driver in a module classpath. If persistence.xml contains no Hibernate-specific database connection options, it should be mapped to an existing data source via JPA facet settings.
Tip: HQL console can also be used to generate DDL statements for JPA and Hibernate mappings via its Generate DDL command.
Update: If a Persistence Unit or Session Factory is mapped to a valid local Data Source there is no need to specify JDBC driver jars in a module classpath (Since 8.1.1).
