Hibernate JPA

jpa hibernate

The Java Persistence API (JPA) is a lightweight, POJO-based framework for Java persistence.
By using a standard persistence API, you can fetch, persist and manage data between Java objects and a Relational Database.
WildFly application server uses Hibernate ORM as JPA Provider. Within this section, you will find tutorials both for Hibernate standalone applications and for Jakarta Persistence API.

Hibernate dynamic-insert and dynamic-update

by

In this tutorial, we’ll explore the @org.hibernate.annotations.Entity annotation and specifically focus on its dynamicInsert and dynamicUpdate properties. These properties can be highly useful in optimizing database interactions by preventing unnecessary SQL updates and inserts. 1. Introduction to @Entity with dynamicInsert and dynamicUpdate Hibernate provides some additional features to the standard JPA annotations. One of these … Read more

Solving “Syntax error in SQL statement: expected “identifier”

by

When working with JPA (Java Persistence API) and defining entity classes, it’s crucial to avoid using reserved words as identifiers for attributes or table names. Failure to do so may lead to SQL syntax errors, as demonstrated by the given issue.

In this tutorial, we’ll walk through the steps to resolve the SQL syntax error caused by using reserved words in a JPA entity class.

How to Configure Level 2 Cache in JPA Applications

by

In this updated article we will learn how to configure Hibernate Second Level Caches with Jakarta Persistence API to optimize database interactions. The primary objective is to minimize the frequency of database hits by strategically implementing caching mechanisms for both entities and queries within the context of the Jakarta Persistence API. Besides, we will also learn how to monitor Caches using WildFly management tools.

3 ways to set a Query timeout for JPA / Hibernate applications

by

In JPA (Java Persistence API) and Hibernate applications, queries can sometimes take a long time to execute, especially when working with large data sets. To avoid long-running queries, it’s important to set a query timeout, which limits the maximum amount of time that a query is allowed to run before it times out. In this tutorial, we will learn how to set a query timeout for JPA/Hibernate applications.

How to lazy load your Entity relations ?

by

This tutorial will teach you how to configure and optimize the fetch type strategy used in your Jakarta EE / Hibernate applications. In JPA terms, the FetchType strategy defines strategies for fetching data from the database. The default FetchType depends on the cardinality of the relationship. Here is a quick summary of defaults: Fetch Strategy … Read more
