I have two entity classes, Order class and OrderLineItems class. I am trying to create a one-many relationship between Order and OrderLineItems, i.e One Order can have multiple OrderLineItems. The code I have is given below.
#Entity
#Table(name = "order")
#Getter
#Setter
#AllArgsConstructor
#NoArgsConstructor
#Builder
public class Order {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long orderId;
private String orderNumber;
#OneToMany(mappedBy = "order")
private List<OrderLineItems> orderLineItems;
}
#Entity
#Getter
#Setter
#Table(name = "order_line_items")
#AllArgsConstructor
#NoArgsConstructor
#Builder
public class OrderLineItems {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long orderLineItemsId;
private String skuCode;
private BigDecimal price;
private Integer quantity;
#ManyToOne(optional = false)
private Order order;
}
The above code results in a SqlSyntaxErrorException. The relevant part of trace is given below. What am I doing wrong?

I am trying to update with null value in uuid column in postgres db using jpa
Here is my code:
#Transactional
#Modifying
#Query(value = "update student set teacher_id=:teacherId where studentId=:studentId", nativeQuery = true)
void updateTeacherUUID(#Param("teacherId") UUID teacherId, #Param("studentId") UUID studentId);
#Data
#Entity
#NoArgsConstructor
#AllArgsConstructor
#Table(name = "student")
public class Student {
#Id
UUID studentId;
#Type(type = "org.hibernate.type.PostgresUUIDType")
#Column(name = "teacher_id", columnDefinition = "uuid")
UUID teacherId;
}
I am getting below error when I try to update
o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 42804
o.h.engine.jdbc.spi.SqlExceptionHelper : ERROR: column "teacher_id" is of type uuid but expression is of type bytea
Hint: You will need to rewrite or cast the expression.
Note: This issue occurring only in jpa native queries If I update directly using repository.update or hql its working fine
Can anyone please help me on this
I am working on a Spring Booot application using Spring Data JPA.
As database I am using PostgreSQL and I am finding some problem mapping an auto increment primary key field of a table to the related field of my entity class.
In my database I manually created this table:
CREATE TABLE IF NOT EXISTS public."user"
(
id bigint NOT NULL GENERATED ALWAYS AS IDENTITY ( INCREMENT 1 START 1 MINVALUE 1 MAXVALUE 9223372036854775807 CACHE 1 ),
first_name character varying(50) COLLATE pg_catalog."default" NOT NULL,
middle_name character varying(50) COLLATE pg_catalog."default" NOT NULL,
surname character varying(50) COLLATE pg_catalog."default" NOT NULL,
CONSTRAINT user_pkey PRIMARY KEY (id)
)
Please not that the id field (my PK) is defined as a bigint with the GENERATED ALWAYS constraint and not as a serial (this because serial data type is deprecated because it is not part of the SQL standard).
Then I created this entity class mapping this table:
package com.easydefi.users.entity;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import lombok.Data;
#Entity
#Table(name = "portal_user")
#Data
public class User implements Serializable {
private static final long serialVersionUID = 5062673109048808267L;
#Id
#Column(name = "id")
private int id;
#Column(name = "first_name")
private String firstName;
#Column(name = "middle_name")
private String middleName;
#Column(name = "surname")
private String surname;
public User(String firstName, String middleName, String surname, char sex, Date birthdate, String taxCode,
String eMail, String contactNumber, Date createdAt) {
super();
this.firstName = firstName;
this.middleName = middleName;
this.surname = surname;
}
}
Then I have this repository interface (at the moment it is empty because I am testing only the save() method directly provided by JpaRepository):
public interface UsersRepository extends JpaRepository<User, Integer> {
}
Finnally I created this simple unit test method in order to test the insert of a new record via the save() method of my repository:
#SpringBootTest()
#ContextConfiguration(classes = GetUserWsApplication.class)
#TestMethodOrder(OrderAnnotation.class)
public class UserRepositoryTest {
#Autowired
private UsersRepository userRepository;
#Test
#Order(1)
public void testInsertUser() {
User user = new User("Mario", null, "Rossi", 'M', new Date(), "XXX", "xxx#gmail.com", "329123456", new Date());
userRepository.save(user);
assertTrue(true);
}
}
the problem is that when the save() method is performed I am obtaining this exception:
Hibernate:
insert
into
portal_user
(first_name, middle_name, surname, id)
values
(?, ?, ?, ?)
2021-11-04 12:17:39.576 WARN 11436 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 428C9
2021-11-04 12:17:39.578 ERROR 11436 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : ERROR: cannot insert a non-DEFAULT value into column "id"
Detail: Column "id" is an identity column defined as GENERATED ALWAYS.
Hint: Use OVERRIDING SYSTEM VALUE to override.
So I try to modify the mapping of the id field into my entity class, in this way:
#Id
#Column(name = "id")
#GeneratedValue(strategy=GenerationType.AUTO)
private int id;
But running my test method now the save() method execution give me this other error:
Hibernate:
select
nextval ('hibernate_sequence')
2021-11-04 12:20:21.133 WARN 11639 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 0, SQLState: 42P01

Position: 17
What is the problem? What am I missing? How can I try to fix this issue?
Change
GeneratedValue(strategy=GenerationType.AUTO)
To
#GeneratedValue(strategy=GenerationType.IDENTITY)
Because GenerationType.IDENTITY create primary key with auto increment that is not modified manually.
The error is definitely on this line.
id bigint NOT NULL GENERATED ALWAYS AS IDENTITY ( INCREMENT 1 START 1 MINVALUE 1 MAXVALUE 9223372036854775807 CACHE 1 ),
If you want a quick fix, you can change it to the one below.
SERIAL works in Postgres just fine. Sure, it might not run on other databases, but how often does an IT project do a DB migration ? Never.
id serial PRIMARY KEY NOT NULL,
Does this solve your problem ? Or you somehow need to solve it without SERIAL for some reason ?
Can you tell me how to fix this exception from console?
org.postgresql.util.PSQLException: ERROR: relation "xxxx" does not exist
This exception is for some tables in my project, and I don't know why. Application works fine without any issues. I have in resources import script dml and tables are filled as well.
Here is my sample implementation table:
#Entity
#Table(name = "USERS")
public class User extends Abstract {
#Column(name = "FIRST_NAME", nullable = false, length = 100)
private String firstName;
#Column(name = "LAST_NAME", nullable = false, length = 100)
private String lastName;
#Column(name = "EMAIL", nullable = false, length = 100)
private String email;
#Column(name = "PASSWORD", nullable = false, length = 60)
private String password;
#Column(name = "PHONE_NUMBER", nullable = false, length = 20)
private String phoneNumber;
#Column(name = "BIRTHDATE", nullable = false, columnDefinition = "TIMESTAMP")
private LocalDateTime birthdate;
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable(
name = "USERS_CONTACTS",
joinColumns = #JoinColumn(name = "USER_ID",
foreignKey = #ForeignKey(name = "FK__USERS__USERS__USER_ID")),
inverseJoinColumns = #JoinColumn(name = "CONTACT_ID",
foreignKey = #ForeignKey(name = "FK__USERS__USERS__CONTACT_ID")))
private List<User> contacts;
// getters and setters
}
and abstract class:
#MappedSuperclass
public class Abstract {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "ID", columnDefinition = "serial")
private Long id;
#Column(name = "CREATED_ON", nullable = false, columnDefinition = "TIMESTAMP")
private LocalDateTime createdOn;
}
Here is full console log:

#Table(name = "POLICY_VALUE_SUMMARY")
public class PolicyValueSummary {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="POLICY_VALUE_SUMMARY_ID")
private Long policyValueSummaryId;
#MapsId("policyValueSummaryId")
#OneToMany
private Set<PolicyValue> policyValues;
}
the child class have composite keys with one is the parent id.
#Entity
#Table(name = "POLICY_VALUE")
public class PolicyValue {
#EmbeddedId
#AttributeOverrides({
#AttributeOverride(name = "policyValueSummaryId", column = #Column(name = "POLICY_VALUE_SUMMARY_ID")),
#AttributeOverride(name = "planAtrId", column = #Column(name = "PLAN_ATR_ID")) })
private PolicyValuePk policyValuePk;
}
This is my child class composite keys.
#Embeddable
public class PolicyValuePk implements Serializable {
private Long policyValueSummaryId;
private Long planAtrId;
}
Im trying to save the policy summary value(parent) with the policy value(child class) like this
PolicyValuePk pk = new PolicyValuePk();
pk.setPlanAtrId(Long.valueOf("1"));
Set<PolicyValue> policyValues = new HashSet<>();
policyValues.add(new PolicyValue(pk));
PolicyValueSummary summary = new PolicyValueSummary();
summary.setPolicyValues(policyValues);
repo.save(summary);
Here is the error that being output to me
Hibernate: select hibernate_sequence.nextval from dual
Hibernate: insert into policy_value_summary (policy_value_summary_id) values (?)
Hibernate: insert into policy_value_summary_policy_values (policy_value_summary_policy_value_summary_id, policy_values_plan_atr_id, policy_values_policy_value_summary_id) values (?, ?, ?)

No, prior to Oracle version 12.2, identifiers are not allowed to exceed 30 characters in length. See the document

Here is DB struckture looking:
and diagram:
I couldn't figure out why it creates hibernate_unique_key table? It shouldn't.
Any suggestions?
well these lines
Hibernate: create table hibernate_unique_key ( next_hi integer )
Hibernate: insert into hibernate_unique_key values ( 0 )
appear because of
#GenericGenerator(name = "hilo-gen", strategy = "hilo")
in your address
hilo: Generates a Integer, long or short type of ids. This uses a High – Low algorithm. As the name suggests, it depends upon the highest table id and then reads the possible lowest available value.
