Develop Reference

How to prevent Hibernate to load collection with back reference when I need only count()

The goal is to count collection elements without initializing collection. I made it work in some way, but it's not the soulution that I'd say I want.
Back reference is needed because each Price gets some data from Article while being indexed by Hibernate Search.
Join column gives me an option to have only two tables, avoiding 3rd linking table.
#Entity #Indexed
class Article {
String name;
#JsonManagedReference
#OneToMany
#LazyCollection(org.hibernate.annotations.LazyCollectionOption.EXTRA)
#JoinColumn(name = "article_id")
#Field(...bridge = #FieldBridge(impl = PriceBridge.class))
Set<Price> prices;
private User created;
private User updated;
}
#Entity #Indexed
class Price {
#Reference #JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#Field(...bridge = #FieldBridge(impl = PriceArticleBridge.class))
private Article article;
#ManyToOne private Provider provider;
#ManyToOne private CustomCurrency currency;
private BigDecimal amount;
private User created;
private User updated;
}
This setup gives me 2 tables where Price table has article_id and there is no 3rd table for linking purposes. But while loading Article and issuing prices.size(), the whole collection is fetched. This is not good because many other entities are loaded too: Provider from Price and User many times because Provider also has its own 2 properties of User to track creator and updater.
When there is no #JoinColumn, 3rd linking table is created and then it starts to use COUNT() instead of loading the whole collection.
My only question is:
How can I keep only 2 tables and use .size() without loading the whole collection?
SQL example when not having #JoinColumn:
select count(prices_id) from article_prices where article_id =?
SQL example when having #JoinColumn (11 tables joined):
SELECT

Not sure about your objectives, however sometime following trick could help:
public class Article {
...
Set<Price> prices;
#Formula("select count(*) from price where article_id=:id")
private int priceCount;
public int getPriceCount() {
if (Hibernate.isInitialized(prices)) {
return prices == null ? 0 : prices.size();
}
return priceCount;
}
}

Performance issue with Criteria API

I am doing a dynamic query using Criteria API, the problem I have is that when this query is executed, each query is repeated for each of the records returned by the query (this is shown by the Hibernate console). Then I get very high response times.
My specification class is as follows:
public class PacienteSpecification implements Specification<Paciente> {
private Paciente filter;
public PacienteSpecification(Paciente filter) {
super();
this.filter = filter;
}
public Predicate toPredicate(Root<Paciente> root, CriteriaQuery<?> cq,
CriteriaBuilder cb) {
Predicate p = cb.conjunction();
p.getExpressions().add(cb.equal(root.get("eliminado"), "N"));
if (filter.getNombres() != "") {
p.getExpressions().add(cb.like(cb.upper(root.get("nombres")), "%" + filter.getNombres().toUpperCase() + "%"));
}
if(filter.getApePaterno() != "") {
p.getExpressions().add(cb.or(cb.like(cb.upper(root.get("apePaterno")), "%" + filter.getApePaterno().toUpperCase() + "%")));
}
if(filter.getApeMaterno() != "") {
p.getExpressions().add(cb.or(cb.like(cb.upper(root.get("apeMaterno")), "%" + filter.getApeMaterno().toUpperCase() + "%")));
}
if (filter.getFicha() != "") {
p.getExpressions().add(cb.equal(cb.upper(root.get("ficha")), filter.getFicha()));
}
if(filter.getFechaNacimiento() != null){
p.getExpressions().add(cb.equal(root.get("fechaNacimiento"), filter.getFechaNacimiento()));
}
if(filter.getGenero() != null){
p.getExpressions().add(cb.equal(root.get("genero"), filter.getGenero()));
}
return p;
}
}
My service that calls the repository is as follows:
List<Paciente> listaPacientes = new ArrayList<Paciente>();
Specification<PacienteDoc> pacienteDocEspecificacion = new PacienteDocEspecification(pacBusqueda.getPacienteDocs().get(0));
final List<PacienteDoc> pacDoc = pacienteDocRep.findAll(pacienteDocEspecificacion);
and when making the service call the hibernate console shows me a query for each record:
Hibernate: select pacientedo0_.id_paciente_doc as id_paciente_doc1_44_, pacientedo0_.eliminado as eliminado2_44_, pacientedo0_.fecha_creacion as fecha_creacion3_44_, pacientedo0_.fecha_ult_modificacion as fecha_ult_modifica4_44_, pacientedo0_.id_usuario_creacion as id_usuario_creacio5_44_, pacientedo0_.id_usuario_ult_mod as id_usuario_ult_mod6_44_, pacientedo0_.num_documento as num_documento7_44_, pacientedo0_.id_paciente as id_paciente8_44_, pacientedo0_.id_tipo_documento as id_tipo_documento9_44_ from dgs_core.paciente_doc pacientedo0_ where 1=1

It seems that Your entity mapping is more or less sth like this:
public class Paciente {
...
#OneToMany(fetch=FetchType.EAGER)
private Set<PacienteDoc> docs = new HashSet<>();
...
}
And then You run into What is the "N+1 selects problem" in ORM (Object-Relational Mapping)?
To fix that simply change #OneToMany(fetch=FetchType.EAGER) to #OneToMany which is equal to #OneToMany(fetch=FetchType.LAZY)

Passing a parameter in a jpql query select

I have a jpql query instanciates a java object in select clause
public List<ChampEtatOT> getEtatOT(Date dateDebut, Date dateFin) {
Query query = em.createQuery("SELECT NEW ChampEtatOT( ot.numero, uo.denominationFr, ot.etat, ot.dateDebutReelle , ot.dateFinReelle, :dateParam1, :dateParam2, :dateParam3) FROM ordre ot JOIN ot.unite uo")
.setParameter("dateParam1", dateDebut, TemporalType.DATE)
.setParameter("dateParam2", dateFin, TemporalType.DATE)
.setParameter("dateParam3", new Date("2015-01-01"), TemporalType.DATE);
return query.getResultList();
}
I put 3 parameters, so i can pass it in the constructor
I get this error
Caused by: Exception [EclipseLink-6137] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.QueryExceptionException Description: An Exception was thrown while executing a ReportQuery with a constructor expression: java.lang.NoSuchMethodException: dz.elit.gmao.commun.reporting.classe.ChampEtatOT.<init>(java.lang.String, java.lang.String, java.lang.String, java.util.Date, java.util.Date)Query: ReportQuery(referenceClass=TravOrdreTravail jpql="SELECT NEW dz.elit.gmao.commun.reporting.classe.ChampEtatOT( ot.numero, uo.denominationFr, ot.etat, ot.dateDebutReelle , ot.dateFinReelle, :dateParam1, :dateParam2, :dateParam3) FROM TravOrdreTravail ot JOIN ot.uniteOrganisationnellle uo")
I think that it's not possible to put parameters in a select clause so does anyone have an idea, the constructor method is as follows:
public ChampEtatOT(String numero, String denominationFr, String etat, Date dateDebutReelle, Date dateFinReelle, Date dateParam1, Date dateParam2, Date dateParam3) {
this.numero = numero;
this.denominationFr = denominationFr;
if (etat.equals("OUV")) {
if (dateDebutReelle.before(dateParam1)) {
etatEntreeSortie = "En instance debut du mois";
} else {
if (dateDebutReelle.before(dateParam2)) {
etatEntreeSortie = "En instance fin du mois";
} else {
if (dateDebutReelle.after(dateParam1) && dateDebutReelle.before(dateParam2)) {
etatEntreeSortie = "Entree/Mois";
}
}
}
}
}

Problem solved, as you suggested bRIMOs Bor it's not possible to pass parameters in a SELECT clause, so i have retreived all the results in a List than filtered the results according to the three dates date1, date2, date3
Query query = em.createQuery("SELECT NEW ChampEtatAteliers"
+ "( ot.numero, uo.denominationFr, ot.etat, ot.dateDebutReelle, ot.dateFinReelle) "
+ "FROM ordre ot JOIN ot.unite uo");
List<ChampEtatAteliers> champEtatAtelierses = query.getResultList();
for (ChampEtatAteliers champEtatAtelierse : champEtatAtelierses) {
if (champEtatAtelierse.getDateDebutReelle().compareTo(date1) >= 0 && champEtatAtelierse.getDateDebutReelle().compareTo(date2) <= 0) {
champEtatAtelierList2.add(new ChampEtatAteliers(champEtatAtelierse.getNumero(), champEtatAtelierse.getDenominationFr(), "Entree/Mois"));
}
if (champEtatAtelierse.getEtat().equals("OUV")) {
if (champEtatAtelierse.getDateDebutReelle().compareTo(date1) < 0) {
champEtatAtelierse.setEtatEntreeSortie("En instance début du mois");
} else {
if (champEtatAtelierse.getDateDebutReelle().compareTo(date2) <= 0) {
champEtatAtelierse.setEtatEntreeSortie("En instance fin du mois");
}
}
}
}

I think that it's not possible to reference a parameter in the contructor.
in your case it throws a NoSuchMethodexeption : it means that, no method with the current signature in your ChampEtatOT class (5 parameters instead of 8 )
you can refer to this answer => Passing a parameter in a jpql query select
So ,try to retrive all data then make a filter method to set all the etatEntreeSortie values inside the ChampEtatOT class of the ResultList

Clearly the JPQL BNF does permit passing parameters as constructor arguments.
constructor_expression ::= NEW constructor_name ( constructor_item {, constructor_item}* )
constructor_item ::= single_valued_path_expression | scalar_expression | aggregate_expression |
identification_variable
scalar_expression ::= simple_arithmetic_expression | string_primary | enum_primary |
datetime_primary | boolean_primary | case_expression | entity_type_expression
string_primary ::= state_field_path_expression | string_literal |
input_parameter | functions_returning_strings | aggregate_expression | case_expression
i.e a scalar_expression can be a string_primary, which can be an input_parameter. So your JPA provider is not meeting the JPA spec and you should raise a bug on it.

[Hive]I got "ArrayIndexOutOfBoundsException" while I query the hive database

I always get "ArrayIndexOutOfBoundsException" while I query the hive base(both hive-0.11.0 and hive-0.12.0), but sometimes not. Here is the error

Sorry, I can't share my samples.
By the way, I've also got this exception before I got "ArrayIndexOutOfBoundException"

Based on the information provided, only this can be a sensible solution to your problem.
I have put the method definition for reference. Please go through it to understand
If you run down the source code closely, there are two areas / possibilities where ArrayIndexOutOfBoundException can be thrown.
Accessing the array values of input splits from Configuration
Reading the Row from currentReadBlock array (this is mostly not the case for the exception since it's size is greater than 0)
Please check your set of input files for job because InputFormat#split() method returns an array of InputSplit type. Each InputSplit is then assigned to an individual Mapper for processing. Mostly, the exception occurs while accessing this InputSplit[] array.

hibernate restrictions.in with and, how to use?

I have table like below
id, employee_no, survey_no, name
1 test 1 test_name
2 test2 1 test_name2
3 test3 1 test_name3
4 test4 2 test_name4
how to query with Restriction.in by combining below AND into one IN statement?
IN[ (if(survey_no==1) && employee_no== 'test') ,
(if(survey_no==1) && employee_no== 'test2') ,
...
]

I think this is the criteria combination you want to use (btw. it is easier to help with the Hibernate entity bean definition instead of the table structure):
String[] employeeNames = { "test", "test2" };
List<Survey> surveys = getSession().createCriteria(Survey.class).add(
Restrictions.and
(
Restrictions.eq("surveyNumber", 1),
Restrictions.in("employeeName", employeeNames)
)
).list();

List<EmployeeSurvey> employeeSurvey = getSession().createCriteria
(EmployeeSurvey.class).add(
Restrictions.and
(
Restrictions.eq("survey_no", 1),
Restrictions.in("employee_name", new String[] {"test", "test1"})
)).list();
