Status

Simple and powerful query builder for your project. Can be use with any existing Hibernate or JPA application.
Stop wasting your time to maintain complex HQL queries and start today with the new generation of query builder.

Quick start

First add this import static org.torpedoquery.jpa.Torpedo.*;

1. Create simple select

	Entity entity = from(Entity.class);
	org.torpedoquery.jpa.Query<Entity> select = select(entity);

2. Create scalar queries

	Entity entity = from(Entity.class);
	org.torpedoquery.jpa.Query<String> select = select(entity.getCode());

3. How to execute your query

	Entity entity = from(Entity.class);
	org.torpedoquery.jpa.Query<Entity> select = select(entity);
	List<Entity> entityList = select.list(entityManager);

4. Create simple condition

	Entity entity = from(Entity.class);
	where(entity.getCode()).eq("mycode");
	org.torpedoquery.jpa.Query<Entity> select = select(entity);

5. Create join on your entities

	Entity entity = from(Entity.class);
	SubEntity subEntity = innerJoin(entity.getSubEntities());
	org.torpedoquery.jpa.Query<String[]> select = select(entity.getCode(), subEntity.getName());

6. Group your conditions

	Entity from = from(Entity.class);
	OnGoingLogicalCondition condition = condition(from.getCode()).eq("test").or(from.getCode()).eq("test2");
	where(from.getName()).eq("test").and(condition);
	Query<Entity> select = select(from);
