People familiar with HQL shouldn't have any problem using EJB-QL. ... Instead, they may be accessed via the parent object. The only reason we might need...

Extend the power of Hibernate with HQL. This query language, designed as 'minimal object-oriented extension to SQL', facilitates writing database-type independent queries that are converted to local SQL dialect of underlying database at runtime. ... The most preferred way is using the Hibernate Query Language (HQL),

In this work we propose a query language, named Versioned Object Query Language (VOQL), that extends ODMG Object Query Language (OQL) with new features to recover object versions. We provide a precise definition of VOQL through a type system and we prove it safe in relation to a small-step operational semantics.
