Java Persistence Query Language
Java Persistence Query Language (JPQL) est un langage de requête orienté objet indépendant de la plateforme, défini dans la spécification Java Persistence API.
JPQL sert à exécuter des requêtes sur des entités persistées en base de données mais en travaillant sur les entités java correspondantes aux tables plutôt que sur les tables elles- mêmes.

The world is amazing: Using native database functions in JPQL
]]> Share at Facebook Java Persistence Query Language(JPQL) is defined by the Java Persistence API(JPA) and it is very easy to use for querying database with entities. But sometime it becomes pretty hard to find similar function in JPQL which is available only in a particular database.

JAVA PERSISTENCE API (JPA) ~ Sunil Gulabani
Introduction Overview The Java Persistence API (JPA) is the Java standard for mapping Java objects to a relational database. Even though proprietary mapping products like Hibernate and TopLink still exist, they are now focused on providing their functionality through the JPA API, allowing all applications to be portable across JPA implementations.

Thinking In Software: Connection is read-only. Queries leading to data modification are not allowed SQL Error: 0, SQLState: S1009
JPA specification does not support changing the transaction isolation level and that is the reason HibernateExtendedJpaDialect and IsolationSupportSessionTransactionData classes have been developed in the wild (Disclaimer: I am merely copying and pasting the ones I found below but all credits go their original authors). We went ahead and tried HibernateExtendedJpaDialect just to notice that randomly entity persistence would fail with: WARN [org.
