How to use detailed SQL query on Srpingboot using #Query?

I'm having some trouble to find out how to use an specific query on Springboot
SELECT tb_excursao.fk_cliente, tb_cliente.nome, tb_cliente.documento, tb_cliente.org_emissor, tb_cliente.data_nascimento, tb_excursao.fk_viagem, tb_viagens.destino, tb_viagens.data_viagem
FROM ((tb_excursao
INNER JOIN tb_cliente ON fk_cliente = tb_cliente.id_cliente)
INNER JOIN tb_viagens ON fk_viagem = tb_viagens.id_viagem))
This works fine on MySQL, but the examples that I saw it's always something like "SELECT u FROM User u", and as a beginner I can't relate using columns from different tables using #Query.
The models are below:
Cliente.java
#Entity
#Table(name = "tb_cliente")
public class Cliente {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long idCliente;
#NotBlank
#Size(min = 3)
private String nome;
#NotNull
private String documento;
#NotNull
private String orgEmissor;
#NotBlank
#JsonFormat(pattern = "dd/MM/yyyy")
private Date dataNascimento;
#Temporal(TemporalType.TIMESTAMP)
private Date dataCadastro = new java.sql.Date(System.currentTimeMillis());
#OneToMany(mappedBy = "fkCliente")
Set<Excursao> excursao;
public long getIdCliente() {
return idCliente;
}
public void setIdCliente(long idCliente) {
this.idCliente = idCliente;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getDocumento() {
return documento;
}
public void setDocumento(String documento) {
this.documento = documento;
}
public String getOrgEmissor() {
return orgEmissor;
}
public void setOrgEmissor(String orgEmissor) {
this.orgEmissor = orgEmissor;
}
public Date getDataNascimento() {
return dataNascimento;
}
public void setDataNascimento(Date dataNascimento) {
this.dataNascimento = dataNascimento;
}
public Date getDataCadastro() {
return dataCadastro;
}
public void setDataCadastro(Date dataCadastro) {
this.dataCadastro = dataCadastro;
}
}
Viagem.java
#Entity
#Table(name = "tb_viagens")
public class Viagem {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long idViagem;
#NotBlank
private String destino;
#NotBlank
#JsonFormat(pattern = "dd/MM/yyyy")
private Date dataViagem;
#NotBlank
private int quantidadeMaxPessoas;
#OneToMany(mappedBy = "fkViagem")

}
}

join two table using hibernate

I have two table entity channel and channel_stats.I want to save data in tables using session.save().
channel_stats can contain duplicate entry with duplicate channel ID.
Can you please tell me how to do so using secondary table annotation in hibernate. or is there any other way? i tried with embedded and embedded annotation bit looks like its for same table

super();
this.channelYoutubeID = channelYoutubeID;
this.channelTitle = channelTitle;
this.thumbnailUrl = thumbnailUrl;
this.activeBit = activeBit;
this.channelStats = channelStats;
}
public int getId() {

+ ", subscriberCount=" + subscriberCount + ", hiddenSubscriberCount=" + hiddenSubscriberCount
+ ", videoCount=" + videoCount + "]";
}
}

As I understand the question, #Embeddable is not what you want in this case. #Embeddable and #Embedded is used when you don't want a separate second table. Since you want a separate table to have the ChannelStat data, it seems like you are trying to create a #OneToMany relationship where one Channel object can have multiple ChannelStat objects.
So your Channel class should have
#OneToMany( mappedBy = "channel", cascade = CascadeType.ALL )
private List<ChannelStat> channelStat;
Instead of
#Embedded
private ChannelStats channelStats;
And your ChannelStat class should have
public class ChannelStats {
// Other variables and their getters and setters
#ManyToOne( cascade = CascadeType.ALL )
#JoinColumn( name = "id" )
private Channel channel;
}

spring boot rest for one to many relation

How should I design this addOrders method?

If you are using Spring Data then you will need to create a CrudRepository for each table you which to access. The CrudRepository allows you to easily manipulate data in your table using standard ORM practices. Here is a link with more details.
For more detailed info on how to use Spring Data check out this wonderful guide. This guide has become indispensable when working with Spring Data.

There are many options to this but i have used below approach so hope it helps you. The #Query annotation allows to execute native queries by setting the nativeQuery flag to true.
#Query(value = "select o.* from customer c inner join order o on c.customer_id = o.customer_id where o. = ?1", nativeQuery = true)
Please write sql according to your requirement.

How to call native query for spring repository(Join three tables and tables haven't any relationship)

I have three tables which called SLSNotification,SLSWorkflow and Importer These tables are not any relationships... I want to get three tables for jasper report.. So I create a native query for it.. It works fine on MySQL... But when i add it to the SLSWorkflowRepository retrieve only workflow class only.. I want to get other classes also from this repository... I think it retrieves only because i write this like this
#Query(value = "select * from slsnotification a join sls_wrkflw b on a.snumber = b.snumber join importers c on c.importer_vat_number = a.importervat where a.importervat = :importerVatNumber and a.snumber = :snumber", nativeQuery = true)
Object getForPrint(#Param("snumber") Long snumber,#Param("importerVatNumber") String importerVatNumber);
can i get other classes for SLSIWorkflow getForPrint() methord...
If i wrong please give some onother way...

How to connect three tables... Please help me someone...

You are getting a SLSIWorkflow only because you are returning that Entity only in the following code in WorkflowServices.
public SLSIWorkflow getApplicationForPrint(Long SNumber, String importerVatNumber) {
return workflowRepository.getForPrint(SNumber, importerVatNumber);
}
If you return an Object it will have all the fields from tables slsnotification, sls_wrkflw, importers as a Object[].
Plus using a Plain JOIN it will result in an INNER JOIN by default. This will not return anything if one joined table doesn't satisfy the ON criteria. It is good if you use LEFT JOIN so that the null will be returned.

My Spring jpaRepository throws a TransactionRequiredException when i'm trying to delete an object

I have a RESTcontroller that has a delete mapping like so:
#DeleteMapping("/deleterequest/{custId}")
//#Transactional
public ResponseEntity<?> delete(#PathVariable long custId) {
log.info("entering deleterequest");
LeaveQuery deleteLeaveQuery = leaveQueryRepository.findOne(custId);
log.info("condition" + deleteLeaveQuery.getStatus().equals("Onbehandeld"));
// if (!deleteLeaveQuery.getStatus().equals("Onbehandeld"))
// return ResponseEntity.badRequest().build();
//deleteLeaveQuery.setAccount(null);
//leaveQueryRepository.save(deleteLeaveQuery);
log.info("is deleteLeaveQuery null? " + (deleteLeaveQuery == null));
//leaveQueryRepository.delete(deleteLeaveQuery);
//leaveQueryRepository.delete(deleteLeaveQuery.getId());
leaveQueryRepository.deleteById(deleteLeaveQuery.getId());
accountService.sendLeaveRequestCanceledNotification(deleteLeaveQuery);
return ResponseEntity.ok().build();
}
When I use the regular (built-in) delete function of my leaveQueryRepository, I get no error, not during log INFO mode nor with log DEBUG mode on. However the object doesn't get deleted either. Its still in the database after the delete method was called. When I make a custom spring repository method called deleteById I get the following error:
org.springframework.dao.InvalidDataAccessApiUsageException: No EntityManager with actual transaction available for current thread - cannot reliably process 'remove' call; nested exception is javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread - cannot reliably process 'remove' call
at
I have no idea what is causing this error. The jparepository looks like this:
#Repository
public interface LeaveQueryRepository extends JpaRepository<LeaveQuery, Long> {
//#Modifying
public void deleteById(long id);
}
The LeaveRequest object looks like this:
#Entity
#JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "id",
scope = LeaveQuery.class)
public class LeaveQuery implements Serializable {
#Id
#GeneratedValue
private Long id;
private Date startDate;
private Date endDate;
private String status = "Onbehandeld";
private String reason ="";
private int totalHours;
private String processedBy;
#ManyToOne(fetch = FetchType.EAGER) //, cascade = CascadeType.PERSIST
#JoinColumn(name = "FK_account", nullable = true)
private Account account;
public String getProcessedBy() {
return processedBy;
}
public void setProcessedBy(String processedBy) {
this.processedBy = processedBy;
}
public int getTotalHours() {
return totalHours;
}
public void setTotalHours(int totalHours) {
this.totalHours = totalHours;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Date getStartDate() {
return startDate;
}
public void setStartDate(Date startDate) {
this.startDate = startDate;
}
public Date getEndDate() {
return endDate;
}
public void setEndDate(Date endDate) {
this.endDate = endDate;
}
public String getReason() {
return reason;
}
public void setReason(String reason) {
this.reason = reason;
}
public Account getAccount() {
return account;
}
public void setAccount(Account account) {
this.account = account;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
#Override
public String toString() {
return "LeaveQuery{" +
"id=" + id +
", startDate=" + startDate +
", endDate=" + endDate +
", denialReason='" + reason + '\'' +
'}';
}
}
It has a relation with an Account object which looks like this:
#Entity
//#JsonIgnoreProperties
//#JsonIdentityInfo(
// generator = ObjectIdGenerators.PropertyGenerator.class,
// property = "id",
// scope = Account.class)
public class Account implements Serializable {
#Id

}
}
Does anyone know what could be causing this error?
Any help would be appreciated.

All controller methods should be none transactional.
You should add one more layer between Controller and Repository (Service layer) and put #Transactional on Service class or put this annotation on your method in this Service class.
It should be Controller -> Service -> Repository
To let #Transactional work you should init TransactionalManager.
You can add something like this in your Persistence Configuration
#Bean
public JpaTransactionManager transactionManager() throws IOException {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
return transactionManager;
}

Use orphanRemoval = true.
Try to update your Account class like so
#JsonIgnore
#OneToMany(fetch = FetchType.EAGER, mappedBy = "account", cascade = CascadeType.ALL, orphanRemoval = true)
List<LeaveQuery> leaveQueryList;
