How to mapping subquery in select with jpa

How to mapping subquery in select with jpa - java

I am using spring ,jpa, hibernate,mysql , java 8,.In Dao (which is inteface and extends JpaRepository)
MyTable class
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;
#Entity
#Table(name = "MY_TABLE")
public class MyTable {
#Id
#Column(name = "ID")
private long id;
#Column(name = "ITEM_NAME")
private String itemName;
#Column(name = "ITEM_PRICE")
private int itemPrice;
#Transient
private int col1;
public MyTable() {
}
public MyTable(long id, String itemName, int itemPrice, int col1) {
super();
this.id = id;
this.itemName = itemName;
this.itemPrice = itemPrice;
this.col1 = col1;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
public int getItemPrice() {
return itemPrice;
}
public void setItemPrice(int itemPrice) {
this.itemPrice = itemPrice;
}
public int getCol1() {
return col1;
}
public void setCol1(int col1) {
this.col1 = col1;
}
}
MyTableDao
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.kolip.devchain.model.MyTable;
public interface MyTableDao extends JpaRepository<MyTable , Long> {

MY_TABLE
CREATE TABLE `my_table` (
`ID` bigint(20) NOT NULL,
`ITEM_NAME` varchar(255) DEFAULT NULL,
`ITEM_PRICE` int(11) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
I try to simplify my problem.I try to get col1 value but i can't find out how should be col1 attribute in entity. Other values can be gotten in entity.
If i use col1 attribute without #Transient , it will work , but col1 is not persistant(Also findAll() not working because there isn't col1 column on db). What should i do ?

you have many options but you could try this the following steps if you are using JPA 2.1:
1) Create a suitable DTO which should include properties that will take the results of your query:
"SELECT mt.*, (select count(1) from anotherTable ) as col1 from MY_TABLE mt"
2) In the MyTable entity, map the native query to your DTO using the #SqlResultSetMapping and #ConstructorResult annotations (a simple search on google will give you lots of usefull info on its usage).(See http://docs.oracle.com/javaee/7/api/javax/persistence/SqlResultSetMapping.html)
3) Modify the MyTableDao to use the native query you created in step 2.
I hope this helps. Goodluck :)

Hibernate uses wrong column name despite all anotations

I am trying to configure simple database using Spring JPA, and I encountered, which seems simular to some questions here, but solution to this aren`t working.
I am trying to insert following POJO into PostgreSQL database :
#Entity
#Table(name = "students", schema = "public")
public class Student {
#Id
#Column(name = "ID")
private UUID id = UUID.randomUUID();
#Column(name = "First_Name")
private String firstName;
#Column(name = "Last_Name")
private String lastName;
#Column(name = "Age")
private Integer age;
#Column(name = "Passport_Number")
private Integer passNumber;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "Group_ID", referencedColumnName = "ID")
private Group group;
public UUID getId() {
return id;
}
public void setId(#NonNull UUID id) { this.id = id; }
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Integer getPassNumber() {
return passNumber;
}
public void setPassNumber(Integer passNumber) {
this.passNumber = passNumber;
}
public Group getGroup() { return group; }
public void setGroup(Group group) { this.group = group; }
public void setUpdate(#NonNull Student student) {
setFirstName(student.getFirstName());
setLastName(student.getLastName());
setAge(student.getAge());
setPassNumber(student.getPassNumber());
}
}
Table of my database is created using following sql :
CREATE TABLE students (
"ID" UUID,
"First_Name" VARCHAR(50),
"Last_Name" VARCHAR(50),
"Age" INT,
"Passport_Number" INT,
"Group_ID" UUID,
UNIQUE("First_Name", "Last_Name"),
UNIQUE("Passport_Number"),
FOREIGN KEY("Group_ID") REFERENCES groups("ID"),
PRIMARY KEY ("ID")
);
When trying to insert new Student, Hibernate builds following sql (message in console) :
Hibernate:
select
student0_.ID as id1_0_0_,
student0_.Age as age2_0_0_,
student0_.First_Name as first_na3_0_0_,
student0_.Group_ID as group_id6_0_0_,
student0_.Last_Name as last_nam4_0_0_,
student0_.Passport_Number as passport5_0_0_
from
public.students student0_
where
student0_.ID=?
And here is the problem. There is no student0_, and so psql off course gives org.postgresql.util.PSQLException: ERROR: column student0_.id does not exist
I tryied also to give name variable to #Entity specifically, but to no effect. Also I tried to change naming stratagies : implicit naming strategy, improved naming strategy, physical naming strategy, implicit legacy naming strategy. And I already tried to change dialect, but also nothing.
My current hibernate properties are :
#Hibernate
hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto = none
hibernate.ejb.naming_strategy = org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
Also this is Configuration that I use :
#Configuration
#EnableTransactionManagement
#PropertySource({"classpath:dao.properties"})
#EnableJpaRepositories(basePackages = {"com.university.dao"})
public class ApplicationConfig {
#Autowired
private Environment environment;
public ApplicationConfig() {
super();
}
#Bean
public DataSource dataSource() {
final BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(Preconditions.checkNotNull(environment.getProperty("jdbc.driverClassName")));
dataSource.setUrl(Preconditions.checkNotNull(environment.getProperty("jdbc.url")));
dataSource.setUsername(Preconditions.checkNotNull(environment.getProperty("jdbc.user")));
dataSource.setPassword(Preconditions.checkNotNull(environment.getProperty("jdbc.password")));
return dataSource;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource,
Environment environment) {
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setDataSource(dataSource);
entityManagerFactory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
entityManagerFactory.setJpaProperties(getHibernateProperties());
entityManagerFactory.setPackagesToScan("com.university.domain");
return entityManagerFactory;
}
#Bean
public PlatformTransactionManager transactionManager() {
final JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory(dataSource(),environment).getObject());
return transactionManager;
}
#Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
final Properties getHibernateProperties() {
final Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", environment.getProperty("hibernate.hbm2ddl.auto"));
hibernateProperties.setProperty("hibernate.dialect", environment.getProperty("hibernate.dialect"));
hibernateProperties.setProperty("hibernate.show_sql", environment.getProperty("hibernate.show_sql"));
hibernateProperties.setProperty("hibernate.format_sql", environment.getProperty("hibernate.format_sql"));
hibernateProperties.setProperty("hibernate.ejb.naming_strategy", environment.getProperty("hibernate.ejb.naming_strategy"));
return hibernateProperties;
}
}

How may I remove this error without explicitly(manually) rewriting hibernate queries in configuration (so hibernate would use correct column/table names automatically)?
Regardless if your answer/comment helps or not, thank you very much for your effort:)

There is a student0_, it's the table alias declared in from student student0_. It's the column that's not being found since it wasn't escaped properly, so student0_.ID really is treated as student0_.id.
Using case sensitive names isn't recommended in Postgres, whereas it's common with other databases. So instead of "First_name", just use first_name. Otherwise you need to escape the names everywhere e.g.
#Column(name = "\"First_Name\"")
and that's not pretty, and all other Postgres users will frown upon your database schema.

I am writing a web app with Spring Boot, Hibernate and PostgreSQL. I want to learn how to save things in DB, but now I can`t resolve my problem. I am getting an error caused by my controller by line:
silniaRepository.save(silniaDB);
error is just:

Your repository is simply not being injected.
You have to put #Autowired for each of the dependencies individauly.
#Autowired
private SilniaService silniaService;
#Autowired
private SilniaRepository silniaRepository;
also make those fields as private..

Spring Boot + Hibernate + Postgres - not creating tables

I am trying to generate schema tables based on entities. The application starts correctly, the SQL is generated but there is no result - none of tables are created. What's wrong? I have used the same settings in plain Spring MVC + Hibernate JPA without Spring Boot and everything was working correctly.
Here is my pom.xml:

}
example of Entity which extends BaseEntity - Entry.java:
package com.agileplayers.applicationname.core.domain;
import javax.persistence.Entity;
import javax.persistence.ManyToOne;
import java.util.Date;
#Entity
public class Entry extends BaseEntity{
private String type;
#ManyToOne
private Account account;
public Entry() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Account getAccount() {
return account;
}
public void setAccount(Account account) {
this.account = account;
}
}

I have fixed the issue. Instead of spring.datasource.schema=schemaName there should be spring.jpa.properties.hibernate.default_schema=schemaName.
The set of necessary properties required for generating tables in my case is the following:
spring.datasource.url = jdbc:postgresql://localhost:5432/postgres
spring.jpa.properties.hibernate.default_schema = schemaName
spring.datasource.username = userName
spring.datasource.password = userPassword
spring.jpa.hibernate.ddl-auto = create-drop
spring.jpa.show-sql = true

java.lang.NoSuchFieldError: name at run time in hibernate project

Trying my hand at my first hibernate (JPA annotations) console application. And I've been running around in circles trying to sort out dependencies, it feels like I'm trying to build a house of cards in a hurricane. Also, I'm using maven, I was under the impression that that maven is supposed to prevent this type of thing.. Anyways this is the error that I'm getting:
Exception in thread "main" java.lang.NoSuchFieldError: name

If I can get some help on this I shall be eternally grateful!

You have two different version dependency for hibernate entity-manager. This will not work. Remove one of them
<dependency>
<groupId>hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.4.0.GA</version>
<exclusions>
<exclusion>
<artifactId>ejb3-persistence</artifactId>
<groupId>org.hibernate</groupId>
</exclusion>
</exclusions>
</dependency>
........................
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.10.Final</version>
</dependency>

try either deleting your slfj dependency entry in your pom, your force the hibernate dependency to exclude it. Hibernate wants to use its own.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.6.10.FINAL</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
</exclusions>
<scope>compile</scope>
</dependency>
etc. Add the same exclusions for hibernate-core etc.

Seems to be a version conflict in the dependencies for artifact slf4j-log4j12.
You could check the output of "mvn dependency:tree" to check for a conflict.
