One To One Query in JPA springboot

-
 One To One Query in JPA springboot In JPA and Spring Boot, you can perform a one-to-one query using JPQL (Java Persistence Query Language) or by using Spring Data JPA's query methods. Assuming you have two entities, let's call them EntityA and EntityB, with a one-to-one relationship between them, you can write a JPQL query to retrieve EntityA and its associated EntityB as follows: @Entity public class EntityA { @Id private Long id; @OneToOne(mappedBy = "entityA") private EntityB entityB; // ... } @Entity public class EntityB { @Id private Long id; @OneToOne @JoinColumn(name = "entity_a_id") private EntityA entityA; // ... } ------------------------------------------------------------------------------ TypedQuery<EntityA> query = entityManager.createQuery(     "SELECT a FROM EntityA a JOIN FETCH a.entityB b WHERE a.id = :id", EntityA.class); query.setParameter("id", entityId); EntityA e...

Many To Many Query in JPA springboot

-
  Many To Many Query in JPA springboot To perform a many-to-many query using JPA in Spring Boot, you will typically need to use the @ManyToMany annotation to map the relationship between the entities. Here are the steps you can follow: Define the entities: Let's say you have two entities, Student and Course , with a many-to-many relationship between them. In the Student entity, you can define the relationship as follows: @Entity public class Student {     @Id     private Long id;     private String name;     @ManyToMany     @JoinTable(             name = "student_course",             joinColumns = @JoinColumn(name = "student_id"),             inverseJoinColumns = @JoinColumn(name = "course_id"))     private Set<Course> courses = new HashSet<>(); } Similarly, in the Course entity, you can define the relationship as foll...

One To Many Query in JPA springboot

-
One To Many Query in JPA springboot In JPA with Spring Boot, you can perform a one-to-many query using the JOIN FETCH clause in a JPQL (Java Persistence Query Language) query. This will allow you to retrieve a single entity and all of its associated child entities in a single database query. Assuming you have an entity named Parent with a one-to-many relationship to Child , where Parent has a Set<Child> property, you can write a JPQL query like this: SELECT p FROM Parent p JOIN FETCH p.children WHERE p.id = :parentId This query will fetch a single Parent entity by its id and eagerly fetch all of its associated Child entities. You can then execute this query using a Spring Data JPA repository interface: public interface ParentRepository extends JpaRepository<Parent, Long> { @Query("SELECT p FROM Parent p JOIN FETCH p.children WHERE p.id = :parentId") Parent findByIdWithChildren(@Param("parentId") Long parentId); } You can then use t...
