I am getting this error while delete a row from a particular schema:
Hibernate: select journal0_.id as id1_2_0_, journal0_.content as content2_2_0_, journal0_.filename as filename3_2_0_, journal0_.subject as subject4_2_0_, journal0_.tags as tags5_2_0_, journal0_.user_id as user_id6_2_0_, journal0_.version as version7_2_0_ from journal journal0_ where journal0_.id=?

Even though the delete method with proper arguments is called still it's running the insert query which is causing data violation issue.
Here is the model:
@Entity
@Table(uniqueConstraints={@UniqueConstraint(columnNames={"userId", "journalId"})})
public class Subscription {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Version
private Integer version;
private Integer userId;
private Integer journalId;
public void setId(Integer id) {
this.id = id;
}
public Integer getId() {
return this.id;
}
public void setVersion(Integer version) {
this.version = version;
}
public Integer getVersion() {
return this.version;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Integer getUserId() {
return this.userId;
}
public void setJournalId(Integer journalId) {
this.journalId = journalId;
}
public Integer getJournalId() {
return this.journalId;
}
}
This is where the delete method is called:
@Override
public void unsubscribeJournalForSubscriber(Journal journal, Account subscriber) {
Subscription subscription = new Subscription();
subscription.setJournalId(journal.getId());
subscription.setUserId(subscriber.getId());
this.subscriptionRepository.delete(subscription);
}
If you want to delete records without using primary key then create a query for that. create a method in the "SubscriptionRepository" called
@Modifying
@Query("delete from Subscription s where s.role. userId = ?1 and s. journalId = ?2")
deleteByUserIdJournalId(Integer userId,Integer journalId)
then use that method to delete your records.
