Hibernate Criteria - sql
I have one class
#Entity
#Table(name = "machine_report")
public class MachineSalesReport implements Serializable, Cloneable {
/**

private static final long serialVersionUID = 1L;
#Id

i want to get all MachineSalesReport,then my dao is
Criteria dc = session.createCriteria(MachineSalesReport.class);
dc.setFetchMode("installationInformation", FetchMode.JOIN);
dc.setFetchMode("customerInformation", FetchMode.JOIN);
dc.setFetchMode("internalInformation", FetchMode.JOIN);
dc.setFetchMode("contracts", FetchMode.JOIN);
dc.setMaxResults(1);
But i find the console show the sql is:

why have so many sql? if i want to set Max(1000),i will get 3000 sql.
I want the first sql,not the all sql.
See below reference
http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/querycriteria.html#querycriteria-dynamicfetching
setFetchMode will fetch subsequent joins also, use createAlias instead

Nested query in JPQL
I have 2 entities -
#Table(name = "MM_MONITORING_CARD")
#Entity(name = "mm_MonitoringCard")
public class MonitoringCard extends StandardEntity {
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "CLIENT_ID")
private Counterparty client;
#Column(name = "START_DATE")
private LocalDate startDate;
#Column(name = "END_DATE")
private LocalDate endDate;
...otherColumn
}
and
#DiscriminatorColumn(name = "TYPE", discriminatorType = DiscriminatorType.STRING)
#Table(name = "MM_COUNTERPARTY")
#Entity(name = "mm_Counterparty")
#DiscriminatorValue("COUNTERPARTY")
#NamePattern("%s|name")
public class Counterparty extends StandardEntity {
#Column(name = "TYPE", insertable=false, updateable=false)
private String type;
...otherColumn
I need get all examples monitoringCard with condition - 1) between start date and end date 2) with Counterparty type = 'someType'
I do method -
List<MonitoringCard> monitoringCardList = dataManager.load(MonitoringCard.class)
.query("select distinct cm from mm_MonitoringCard m join mm_Counterparty cm where (m.current_date between cm.startDate and cm.endDate) and cm.type = :type")
.parameter("type", "someType")
.list();
but i get error, how can i make a correct request?
thanks
Your query is not correct. It should use a join like this: select distinct m.Counterparty from mm_MonitoringCard m where (m.current_date between m.Counterparty.startDate and m.Counterparty.endDate) and m.Counterparty.type = :type In JPA you don't need to do an explicit join when navigating on a ToOne relationship.
Hibernate query exception:cannot dereference scalar collection element
I am getting following error after starting my spring application:
Caused by: java.lang.IllegalArgumentException: org.hibernate.QueryException: cannot dereference scalar collection element: metadata_descriptor_id [SELECT d FROM com.org.entity.documents.Document d INNER JOIN d.documentMetadata md ON md.document_id = d.id WHERE (md.metadata_descriptor_id.id NOT IN (:documentMetadataId))]
Here is my Document class:
#Entity
#Table(name = "documents")
public class Document {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private long id;
#Column(name = "name", nullable = false, unique = true)
private String name;
#Column(name = "archived", nullable = false)
private boolean archived;
#Column(name = "creation_date", nullable = false)
private Instant creationDate;
#Column(name = "file_text_processing_status", nullable = false)
#Enumerated(EnumType.STRING)
private FileTextProcessingStatus fileTextProcessingStatus;
#ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name = "template_file_id", referencedColumnName = "id")
private TemplateFile templateFile;
#ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name = "state_descriptor_id", referencedColumnName = "id")
private StateDescriptor stateDescriptor;
#ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name = "user_id", referencedColumnName = "id")
private UserEntity user;
#ElementCollection(targetClass = String.class)
#Column(name = "tag", nullable = false)
#CollectionTable(name = "document_tags", joinColumns = #JoinColumn(name = "document_id"))
private Set<String> tags = new HashSet<>();
#ElementCollection
#CollectionTable(name = "document_metadata", joinColumns = {
#JoinColumn(name = "document_id", referencedColumnName = "id")})
#MapKeyJoinColumn(name = "metadata_descriptor_id", referencedColumnName = "id")
#Column(name = "value", nullable = false)
private Map<MetadataDescriptor, String> documentMetadata = new HashMap<>();
#OneToMany(mappedBy = "document", cascade = CascadeType.ALL, orphanRemoval = true)
private Set<DocumentFileVersion> documentVersions = new HashSet<>();`enter code here`
And here is Repository method that fails:
#Lock(LockModeType.PESSIMISTIC_WRITE)
#Query(value = "SELECT d FROM Document d INNER JOIN d.documentMetadata md ON md.document_id = d.id"
+ " WHERE (md.metadata_descriptor_id NOT IN (:documentMetadataId))")
List<Document> findAllByDocumentRequiredMetadataNotSet(long documentMetadataId);
I have seen an answer for similar question here: getting Caused by: org.hibernate.QueryException: cannot dereference scalar collection element: roles
But it's not helpful in my case. I will be very glad for any suggestions.
The type of md is String this is why you see an error. What you need is something like this: #Lock(LockModeType.PESSIMISTIC_WRITE) #Query(value = "SELECT d FROM Document d INNER JOIN d.documentMetadata md WHERE (KEY(md).id NOT IN (:documentMetadataId))") List<Document> findAllByDocumentRequiredMetadataNotSet(long documentMetadataId); You also had a ON clause which is no necessary/wrong. I think you should read into HQL/JPQL first as you don't seem to understand that a join of an association, will add the join predicate in the SQL automatically. Note though, that the syntax KEY(..).id is only supported in newer Hibernate versions, so you might have to update.
How to convert my native SQL query into a JPQL query
I'm trying to convert a native SQL query into a JPQL query. Presented first are the JPA entities and the repository interface:
LearnerActivity
#Entity
#Table(name = "learner_activity")
public class LearnerActivity implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#ManyToMany
#JoinTable(name = "learner_activity_unit",
joinColumns = #JoinColumn(name="learner_activitys_id", referencedColumnName="ID"),
inverseJoinColumns = #JoinColumn(name="units_id", referencedColumnName="ID"))
private Set<Unit> units = new HashSet<>();
#ManyToMany
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
#JoinTable(name = "learner_activity_performance_criteria",
joinColumns = #JoinColumn(name="learner_activitys_id", referencedColumnName="ID"),
inverseJoinColumns = #JoinColumn(name="performance_criterias_id", referencedColumnName="ID"))
private Set<PerformanceCriteria> performanceCriterias = new HashSet<>();
}
LearnerJobOnSiteChecklistSectionItem
#Entity
#Table(name = "learner_job_on_site_checklist_section_item")
public class LearnerJobOnSiteChecklistSectionItem implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#ManyToOne
#JoinColumn(name = "learner_activity_id")
private LearnerActivity learnerActivity;
}
LearnerPortfolioPerformanceCriteriaAchievement
#Entity
#Table(name = "learner_portfolio_performance_criteria_achievement")
public class LearnerPortfolioPerformanceCriteriaAchievement implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#ManyToOne
#JoinColumn(name = "performance_criteria_id")
private PerformanceCriteria performanceCriteria;
#ManyToMany
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
#JoinTable(name = "learner_portfolio_performance_criteria_achievement_learner_job_on_site_checklist_section_item",
joinColumns = #JoinColumn(name="learner_portfolio_performance_criteria_achievements_id", referencedColumnName="ID"),
inverseJoinColumns = #JoinColumn(name="learner_job_on_site_checklist_section_items_id", referencedColumnName="ID"))
private Set<LearnerJobOnSiteChecklistSectionItem> learnerJobOnSiteChecklistSectionItems = new HashSet<>();
}
I'm looking to get all LearnerPortfolioPerformanceCriteriaAchievements which have the same PerformanceCriteria as a given LearnerJobOnSiteChecklistSectionItem's Activity.
LearnerPortfolioPerformanceCriteriaAchievementRepository
public interface LearnerPortfolioPerformanceCriteriaAchievementRepository extends JpaRepository<LearnerPortfolioPerformanceCriteriaAchievement,Long> {
#Query("select distinct lppca from LearnerJobOnSiteChecklistSectionItem si inner join si.learnerActivity la inner join LearnerPortfolioPerformanceCriteriaAchievement lppca where lppca.performanceCriteria member of la.performanceCriterias and si.id =:sectionItemId")
public List<LearnerPortfolioPerformanceCriteriaAchievement> findForSectionItem(#Param("sectionItemId") Long sectionItemId);
}
Native SQL
SELECT
a.id
FROM
learner_job_on_site_checklist_section_item AS i
JOIN
learner_activity_performance_criteria AS c
ON
c.learned_activitys_id = i.learned_activitys_id
INNER JOIN
learner_portfolio_performance_criteria_achievement AS a
ON
a.performance_criteria_id = c.performance_criterias_id
where i.id = 2
Understanding that I can replace my SQL ON with WHERE clauses, my best JPQL attempt so far is this:
SELECT
DISTINCT lppca
FROM
LearnerJobOnSiteChecklistSectionItem si
INNER JOIN
si.learnerActivity la
INNER JOIN
LearnerPortfolioPerformanceCriteriaAchievement lppca
WHERE
lppca.performanceCriteria MEMBER OF la.performanceCriterias
AND si.id =:sectionItemId
However, running this JPQL throws the following exception:
Caused by: java.lang.IllegalStateException: No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode
\-[IDENT] IdentNode: 'lppca' {originalText=lppca}
The following query will work: SELECT a FROM LearnerPortfolioPerformanceCriteriaAchievement a , LearnerActivity v , LearnerJobOnSiteChecklistSectionItem i WHERE i.id = :sectionItemId AND i.learnerActivity = v AND a.performanceCriteria MEMBER OF v.performanceCriterias AND i MEMBER OF a.learnerJobOnSiteChecklistSectionItems Have created a sample application to test the query (I have used shorter and simpler class names to make it easy to read).

When I try to get the kpis list from ProcessVersion I always get 0. I check the sql generated by hibernate and I see this sentece wich is very strage:

The question is why the sentece has 3 inner with stage..Two from KpiTemporary and One from KpiCounter the problem is this will never have the 3 values because the kpi is temporary or is counter but not both.
Can anyone tell me something about?. Is there any extra config to apply. I am using JPA 2.1 specification with hinerbate 4.3.5.Final
The problem is that you have 3 mappings of: #ManyToOne(optional = false) On both counter and temporary. The false means that the mapping is 1..M -> 1, while true would mean the mapping is 0..M ->1, I think you would want the latter. Change those to true and see if you get the sql you desire.
java.lang.IllegalArgumentException with toplink and JPA
I've a problem with JPA, whenever execute this query
#NamedQuery(name = "Usuario.getUsuarioIntento", query = "SELECT u.intentos_id FROM Usuario u WHERE u.username = :username and u.borrado = 0")
i get this error:
java.lang.IllegalArgumentException: NamedQuery of name: Usuario.getUsuarioIntento not found.
But if i execute this query
#NamedQuery(name = "Usuario.getUsuarioIntento", query = "SELECT u.id FROM Usuario u WHERE u.username = :username and u.borrado = 0")
Work fine,Why?

i try with other column as 'superusuario','version_jpa' and doesn't work, the only columns that work fine are 'id,'borrado' and 'username'

Because Named query works on Entity objetc not on datbase column. You try to find another entity object which contains that id. In That case your named query will give you the object of that entity class and from that object u can get the id or whtever fiels of that entity. JPA named query is not like SQL or oracle query. Iin in DB your column name is xyz but in entity your column name is ABC then you have to fetch ABC in named query not XYZ.
