Returning joined columns from different tables using JPA native query

Below are the mapped entities : Camapaign -> Question -> Choice
#Entity
public class Campaign
{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long campaignId;
private String campaignName;
private String campaignDescription;
private int noOfQuestions;
private int noOfChoices;
private Date lastUpdatedTime;
private Date createdTime;
private boolean isActivated;
#JsonManagedReference
#OneToMany(mappedBy = "campaign",cascade=CascadeType.ALL)
private Set<Question> questions;
#Entity
public class Question
{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long questionId;
private String question;
#JsonManagedReference
#OneToMany(mappedBy = "question",cascade=CascadeType.ALL)
private Set<Choice> choices;
private String correctAnswer;
private String correctAnswerDescription;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="CAMPAIGN_ID")
private Campaign campaign;
#Entity
public class Choice
{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long choiceId;
private String choice;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="QUESTION_ID")
private Question question;
And another mapped entities : QuizUsers -> AttendedQuestions
#Entity
#Table(name="quiz_users")
public class QuizUser
{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long userId;
private String emailId;
private String fullName;
private long mobileNumber;
private long attendedCampaignId;
private boolean isSubmittedQuiz;
private boolean isEvaluated;
private long correctAnswerCount;
#JsonManagedReference
#OneToMany(mappedBy = "quizUser",cascade=CascadeType.ALL)
private Set<AttendedQuestions> questions;
#Entity
public class AttendedQuestions
{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private long attendedQuestionId;
private String answeredChoice;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="USER_ID")
private QuizUser quizUser;
All the entities have their respective getters and setters
Now my requirement is to join and select some of the columns by executing the following MySQL query(alternative JPQL query would be acceptable) :
SELECT C.campaign_id,C.campaign_name,U.full_name,U.mobile_number,
U.email_id,COUNT(Q.correct_answer) AS correct_answers
FROM campaign C INNER JOIN quiz_users U ON C.campaign_id = U.attended_campaign_id
LEFT JOIN attended_questions AQ ON U.user_id = AQ.user_id
LEFT JOIN question Q ON AQ.answered_choice = Q.correct_answer
This is my repository:
#Repository
public interface EvaluatedResultRepository extends JpaRepository<Campaign, Long>
{
public static final String QUERY = "SELECT C.campaign_id,C.campaign_name,U.full_name,U.mobile_number,U.email_id,COUNT(Q.correct_answer) AS correct_answers FROM campaign C INNER JOIN quiz_users U ON C.campaign_id = U.attended_campaign_id LEFT JOIN attended_questions AQ ON U.user_id = AQ.user_id LEFT JOIN question Q ON AQ.answered_choice = Q.correct_answer";
#Query(value = QUERY, nativeQuery = true)
public Collection<EvaluatedResult> findAllEvaluatedResult();
}
EvaluatedResult is my DTO and I have tried making it a class or interface(with getters only) for projections and tried selecting it.
I have also tried changing the T in JpaRepository<T.. to QuizUsers but everytime it is returning :
java.lang.NullPointerException: null
Please help in giving a solution. Thanks in advance
Full stacktrace :
java.lang.NullPointerException: null

Edit : I am able to get the result of the query in MySQL workbench.

I have solved the error,
It was a simple mistake.
I didn't #Autowired evaluatedRepo.
After that the Null Pointer Exception went away.
The structure of the return JSON was messed up, so I will paste the solution here for future references for anyone else :
public static final String MYSQL = "SELECT C.campaign_id,C.campaign_name,C.no_of_questions,U.full_name,U.mobile_number,U.email_id,COUNT(Q.correct_answer) FROM campaign C INNER JOIN quiz_users U ON C.campaign_id = U.attended_campaign_id LEFT JOIN attended_questions AQ ON U.user_id = AQ.user_id LEFT JOIN question Q ON AQ.answered_choice = Q.correct_answer";
#Query(value = MYSQL,nativeQuery = true)
public List<Object[]> findAllEvaluatedResult();
Service Layer processing the returned result from Repo :
public List<EvaluatedResult> evaluateQuiz(long campaignId)
{
List<EvaluatedResult> evaluatedResults = new ArrayList<>();
List<Object[]> joinedResults = null;
joinedResults = evaluatedRepo.findAllEvaluatedResult();
List<QuizUser> quizUsers = quizUserRepo.findByAttendedCampaignId(campaignId);
for(Object[] array : joinedResults)
{
EvaluatedResult eR = new EvaluatedResult();
eR.setCampaignId(bigIntToLong(array[0]+""));
eR.setCampaignName((String)array[1]);
eR.setNumberOfQuestions((int)array[2]);
eR.setFullName((String)array[3]);
eR.setMobileNumber(bigIntToLong(array[4]+""));
eR.setEmailId((String)array[5]);
eR.setCorrectAnswers(bigIntToLong(array[6]+""));
evaluatedResults.add(eR);
}
return evaluatedResults;
}
private long bigIntToLong(String num)
{
BigInteger bigInt = new BigInteger(num);
long campaignId = bigInt.longValue();
return campaignId;
}
I made a simple mistake and it was resolved

JOOQ version: 3.15
Spring Boot version: 2.7.5
Java version: 17

Why your approach doesn't work
You're creating a flat result set from your one-to-many relationship between POSTS and COMMENTS, and then, you're expecting jOOQ's DefaultRecordMapper (via the fetchInto(Class) method) to de-duplicate those flat results again automatically for you. But that's not how things work in jOOQ. While you know the relationship between POSTS and COMMENTS in your query, a flat jOOQ Result does not. There's no obvious way how to auto-deduplicate stuff. Imagine, you had several nested collections in Post, how would that even work?
Using MULTISET to nest collections
The most jOOQ and SQL idiomatic way to nest collections is to use MULTISET, along with ad-hoc converters, e.g. like this:
List<Post> result =
dslContext
.select(
POSTS.ID,
POSTS.CONTENT,
POSTS.CREATED_AT,
multiset(
select(COMMENTS.ID, COMMENTS.CONTENT, COMMENTS.CREATED_AT)
.from(COMMENTS)
.where(COMMENTS.POST_ID.eq(POSTS.ID))
).convertFrom(r -> r.map(Records.mapping(Comment::new))))
.from(POSTS)
.fetch(Records.mapping(Post::new));

#Lukas Eder
I've written this method using multisetAgg. It works ok but i'm not sure it should look like this:
List<Post> getAllPost() {
List<Post> result =
dslContext
.select(
POSTS.ID,
POSTS.CONTENT,
POSTS.CREATED_AT,
multisetAgg(
COMMENTS.ID, COMMENTS.CONTENT, COMMENTS.CREATED_AT, COMMENTS.POST_ID
).as("comments").convertFrom(r -> r.into(Comment.class))
)
.from(POSTS)
.leftJoin(COMMENTS).on(COMMENTS.POST_ID.eq(POSTS.ID))
.groupBy(POSTS.ID)
.fetchInto(Post.class);
return result;
}

TransientPropertyValueException: object references an unsaved transient instance on PUT request

I'm getting this error (below) when I make a put request to update a superhero with new properties. I've added CascadeType.ALL to Superhero for the Superhero-Powerstats association. Seeing as it's a one-to-one relationship I thought that's all I need to do. I still seem to be getting an error. Anyone know what's going on?

Table question (i get it from DataGrip Documentation)
create table question
(
id bigint auto_increment
primary key,
name varchar(255) null,
question_theme_id bigint null,
constraint FKnmogm1ug9iu4q4m9oyg291ocu
foreign key (question_theme_id) references test_theme (id)
);
Table test_theme
create table test_theme
(
id bigint auto_increment
primary key,
name varchar(255) null
);
Question: Why this error occurs and how to fix it?
I will also be grateful if you can point me out to my mistakes that I made when designing the project. Thank you!
--- Edit ----
create table answer_list
(
question_id bigint not null,
answer_id bigint not null,
constraint UK_g74668cehn4p20wkd08q7ki1l
unique (answer_id),
constraint FKkjnmyxuv540sqjlbbv2swl5nk
foreign key (question_id) references question (id),
constraint FKkwrnjix7ebw7frlua0ccja025
foreign key (answer_id) references answer (id)
);
-- Edit how to fix my problem ---
Drop all tables from database
Change #OneToMany to #ManyToMany in Question
Restart application
3.1) table answer_list no longer has unique keys :)
Fixed.

You are saving the same instance answer multiple times for question, question2 and so on.
If "None" should be saved for each question in a seperate Answer-record, you should create a new instance of the answer for each question.
Question question = new Question(question_theme, "What hurts?", Arrays.asList(createAnswer1(), createAnswer2(), createAnswer3()));
Question question2 = new Question(question_theme, "Rotations?", Arrays.asList(createAnswer1(), createAnswer2()));
Question question3 = new Question(question_theme2, "Extension", Arrays.asList(createAnswer1()));
private void createAnswer1(){ return new Answer("None", 1);}
private void createAnswer2(){ return new Answer("Easy", 2);}
private void createAnswer3(){ return new Answer("Meduim", 3);}
If the same record of "None" should be used for all the questions, first save each answer-record and use the return value of 'save(...)' to add them to the question (they are called attached after save).
Answer answer = answerRepo.save(new Answer("None", 1));
Answer answer2 = answerRepo.save(new Answer("Easy", 2));
Answer answer3 = answerRepo.save(new Answer("Meduim", 3));
Question question = new Question(question_theme, "What hurts?", Arrays.asList(answer , answer2 , answer3 ));
Question question2 = new Question(question_theme, "Rotations?", Arrays.asList(answer , answer2 ));
Question question3 = new Question(question_theme2, "Extension", Arrays.asList(answer ));

ORA-00904: invalid identifier when i insert to a table

I have a Results table that has 3 foreign keys in it. I created 3 #OneToMany relationships but i think i did something wrong because i cannot insert into Result table.
Results has an Id, Answer_id, Question_id and Student_id.
Answer_id is referencing to Answers.answ_id
Question_id is referencing to Question.qst_id
Student_id to Student_Dim.stu_id.
Results class :
#Entity
#Table(name = "results")
public class Results {
#Id
#GeneratedValue(strategy = GenerationType.AUTO, generator = "my_generator")
#SequenceGenerator(name = "my_generator", sequenceName = "MY_SEQUENCE", allocationSize = 1)
#Column(name = "id", unique = true)
private int id;
#Column(nullable = false)
private String question_id;
#Column(nullable = false)
private String answer_id;
#Column(nullable = false)
private String student_id;
#ManyToOne(fetch = FetchType.LAZY, targetEntity = Questions.class)
#JoinColumn(name = "qst_id")
private Questions question;
#ManyToOne(fetch = FetchType.LAZY, targetEntity = Answers.class)
#JoinColumn(name = "answ_id")
private Answers answer;
#ManyToOne(fetch = FetchType.LAZY, targetEntity = Student_Dim.class)
#JoinColumn(name = "stu_id")
private Student_Dim student;
Student_Dim class:
#Entity
#Table(name="student_dim")
public class Student_Dim {
#Id
#Column(name="stu_id", unique = true)
private String stu_id;
#Column(nullable = false)
private String stu_fname;
#Column(nullable = false)
private String stu_lname;
#Column(nullable = false)
private String dep_code;
#Column(nullable = false)
private String fac_code;
#Column(nullable = false)
private String loc_code;
#Column(nullable = false)
private String password;
#Column
private String marriage_status;
#Column
private String address;
#Column(nullable = false)
private boolean enabled;
#ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
#JoinTable(
name = "user_roles",
joinColumns = #JoinColumn(name = "user_id"),
inverseJoinColumns = #JoinColumn(name = "role_id")
)
private Set<Roles> roles = new HashSet<>();
#OneToMany(mappedBy="student",fetch = FetchType.LAZY, cascade =
CascadeType.ALL) private Set<Results> result;
Student_Dim table:
student_dim
Answers class:
#OneToMany(mappedBy="answer",fetch = FetchType.LAZY, cascade =
CascadeType.ALL) private Set<Results> result;
Questions class:
#OneToMany(mappedBy="question",fetch = FetchType.LAZY, cascade = CascadeType.ALL)
private Set<Results> result;
My insert in ResultService:
public void saveOrUpdate(List<String> list){
Results res = new Results();
res.setQuestion_id("qst1");
res.setAnswer_id("answ2");
res.setStudent_id("stud3");
resultRepository.save(res);
}
I got this error when i want to insert in the Result table. It is working without the #OneToMany, #ManyToOne relationships. What do i wrong?
