#Repository
public interface TestNativeQRepository extends CrudRepository<TestNativeQ, String> {
#Query( value="SELECT qplt.name price_list_name, qplab.status_code, qplab.start_date, (SELECT charge_definition_code FROM oalfsaas_repl.QP_CHARGE_DEFINITIONS_B WHERE charge_definition_id=qplab.charge_definition_id ) chargedefinitioncode "

public List<TestNativeQDTO> getAllDetails();
}
Actual Result:
[{"ABC", "DEF", "15/05/2018", "XXZ"}]
Expected Result
[{name: "ABC", statuscode: "DEF", startDate: "15/05/2018", chargedefintioncode: "XXZ"}]
As #Nikolay gave hint in comment.
The result of native query is not automatically transformed to an Entity, you must do it manually or define mappings via #SqlResultSetMapping and #ColumnResult.
to make that work follow the below code.
#Entity
#Configurable
#SqlResultSetMapping(name = "someName", entities = #EntityResult(entityClass = SamplePojo.class), columns = #ColumnResult(name = "columnName"))
public class SamplePojo{
//fields and getters/setters
}
and Then in query
List<SamplePojo> list = entityManager().createNativeQuery("Select ......", "someName").getResultList();
Note : someName should be same in both places.

I am trying to sort my table's content on the backend side, so I am sending org.springframework.data.domain.Pageable object to controller. It arrives correctly, but at the repository I am getting org.hibernate.hql.internal.ast.InvalidPathException. Somehow the field name I would use for sorting gets an org. package name infront of the filed name.
The Pageable object logged in the controller:
Page request [number: 0, size 10, sort: referenzNumber: DESC]
Exception in repository:
Invalid path: 'org.referenzNumber'","logger_name":"org.hibernate.hql.internal.ast.ErrorTracker","thread_name":"http-nio-8080-exec-2","level":"ERROR","level_value":40000,"stack_trace":"org.hibernate.hql.internal.ast.InvalidPathException: Invalid path: 'org.referenzNumber'\n\tat org.hibernate.hql.internal.ast.util.LiteralProcessor.lookupConstant(LiteralProcessor.java:111)
My controller endpoint:
#GetMapping(value = "/get-orders", params = { "page", "size" }, produces = { MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<PagedModel<KryptoOrder>> getOrders(
#ApiParam(name = "searchrequest", required = true) #Validated final OrderSearchRequest orderSearchRequest,
#PageableDefault(size = 500) final Pageable pageable, final BindingResult bindingResult,
final PagedResourcesAssembler<OrderVo> pagedResourcesAssembler) {
if (bindingResult.hasErrors()) {
return ResponseEntity.badRequest().build();
}
PagedModel<Order> orderPage = PagedModel.empty();
try {
var orderVoPage = orderPort.processOrderSearch(resourceMapper.toOrderSearchRequestVo(orderSearchRequest), pageable);
orderPage = pagedResourcesAssembler.toModel(orderVoPage, orderAssembler);
} catch (MissingRequiredField m) {
log.warn(RESPONSE_MISSING_REQUIRED_FIELD, m);
return ResponseEntity.badRequest().build();
}
return ResponseEntity.ok(orderPage);
}
the repository:
#Repository

static final String SEARCH_ORDER = "SELECT o" //
+ " FROM Order o " //

#Query(SEARCH_ORDER)

#Param("accountnumber") BigDecimal accountnumber, #Param("orderReference") Long orderReference,
#Param("orderReferenceExtern") String orderReferenceExtern, #Param("dateFrom") LocalDateTime dateFrom,
#Param("dateTo") LocalDateTime dateTo, Pageable pageable);
}
Update:
I removed the parameters from the sql query, and put them back one by one to see where it goes sideways. It seems as soon as the dates are involved the wierd "org." appears too.
Update 2:
If I change cast(:dateTo as org.hibernate.type.DateType) to cast(:dateFrom as date) then it appends the filed name with date. instead of org..
Thanks in advance for the help
My guess is, Spring Data is confused by the query you are using and can't properly append the order by clause to it. I would recommend you to use a Specification instead for your various filters. That will not only improve the performance of your queries because the database can better optimize queries, but will also make use of the JPA Criteria API behind the scenes, which requires no work from Spring Data to apply an order by specification.
Since your entity Order is named as the order by clause of HQL/SQL, my guess is that Spring Data tries to do something stupid with the string to determine the alias of the root entity.
Spring Boot JPA select Specific Columns result should in JSON Format
#Query(value = "SELECT id, property_id, display_name FROM property_basic_property_details WHERE status='1' and unique_id=:unique_id", nativeQuery = true)
public List propertydisplayname(String unique_id);
#GetMapping("/propertydisplayname/{unique_id}")
public List<PropertyBasicPropertyDetails> propertydisplayname(#PathVariable String unique_id){
List<PropertyBasicPropertyDetails> PropertyBasicPropertyDetails1= propertyBasicPropertyDetailsRespository.propertydisplayname(unique_id);
return PropertyBasicPropertyDetails1;
}
error:
could not execute query; SQL [SELECT id, property_id, display_name FROM property_basic_property_details WHERE status='1' and unique_id=?]
Output:

}
In your Repository where you defined the query, mention List<Entity_Name> prior to mentioning the function.
#Query(value = "SELECT id, property_id, display_name FROM property_basic_property_details WHERE status='1' and unique_id=:unique_id", nativeQuery = true)
public List<PropertyBasicPropertyDetails> propertydisplayname(String unique_id);
In the Controller, (the same way you defined without an object included, doesn't make any difference though)
#GetMapping("/propertydisplayname/{unique_id}")
public List<PropertyBasicPropertyDetails> propertydisplayname(#PathVariable String unique_id){
return propertyBasicPropertyDetailsRespository.propertydisplayname(unique_id);
}
Not able to use custom POJO classes for my spring data jpa queries. Repeatedly fails with the following exception
"org.hibernate.MappingException: Unknown entity:
com.app.mycompany.AgileCenterServices.entities.ComponentDetailedInfo"*
Tried replacing the custom ComponentDetailedInfo.class and not mentioning anything during the call to entityManager.createNativeQuery(componentQuery.toString()), but then Object List returned fails to be converted to the specific POJO class after the query.
#Override
public ComponentListResponsePaginated findComponentByProjectId(String projectId, Pageable pageable) {
logger.info(" Inside findComponentByProjectId() API in IssueComponentServiceImpl");
String componentQuery = "select c.*, u.fullname "
+ "from issue_component c "
+ "left join user u on c.component_lead = u.username "
+ "where "
+ "upper(c.project_id) = upper(" + projectId + ")";
List<ComponentDetailedInfo> compList = new ArrayList<ComponentDetailedInfo>();
try {
logger.info(" ************* Printing query ******************************* ");
logger.info(componentQuery.toString());
compList = entityManager.createNativeQuery(componentQuery.toString(), ComponentDetailedInfo.class) .setFirstResult(pageable.getOffset())
.setMaxResults(pageable.getPageSize())
.getResultList();
}
}
Also tried the following
List<? extends Object> objList = null;
objList = entityManager.createNativeQuery(componentQuery.toString()) .setFirstResult(pageable.getOffset())
.setMaxResults(pageable.getPageSize())
.getResultList();
if(objList != null && objList.size() > 0) {
for(Object rec: objList) {
logger.info(" Printing Object ::: " + rec.toString());
compList.add((ComponentDetailedInfo)rec);
}
}
However the compList fails with the
java.lang.ClassCastException
The custom query returned should get typecast to the specific class type passed to the entityManager.createNativeQuery. However, I am facing the exception as mentioned above when I pass the class to createNativeQuery().
Even tried by totally removed the class in the createNativeQuery...
You have to define a constructor result mapping if you want to use a POJO as a result of a native query.
Here is an example query:
Query q = em.createNativeQuery(
"SELECT c.id, c.name, COUNT(o) as orderCount, AVG(o.price) AS avgOrder " +
"FROM Customer c " +
"JOIN Orders o ON o.cid = c.id " +
"GROUP BY c.id, c.name",
"CustomerDetailsResult");
And that's the mapping you have to add to your Entity:
#SqlResultSetMapping(name="CustomerDetailsResult",
classes={
#ConstructorResult(targetClass=com.acme.CustomerDetails.class,
columns={
#ColumnResult(name="id"),
#ColumnResult(name="name"),
#ColumnResult(name="orderCount"),
#ColumnResult(name="avgOrder", type=Double.class)})
})
If you don't like that approach you could use QLRM. Learn more about it here: https://github.com/simasch/qlrm
I have a case statement in my Native query where I am attempting to override a field in my entity.
SELECT i.id, i.ONE_TO_ONE_ID, i.ANOTHER, CASE(WHEN condition THEN 'YES' WHEN another_condition THEN 'NO' ELSE 'MAYBE' END) as word ....
I am using this with JpaRepository as a native query, with pagination.
When I run the native query against my db directly, the result set looks as though I expect.
| id_value | MAPPED_ENTITY_ID_value | another value | word_value (YES) |
When I run the native query from my JpaRepository, everything works there, except word is always null. I cant' seem to figure out how to map the additional String word result to a field in my Entity.
Is there a way to get this to map? Or will I have to create an entire #SqlResultSetMapping() for all of my fields coupled with a native query? (hoping not)
UPDATE: 1
I was generalizing above. Here is my Query.
#Query(
name = "listPagedMapping",
value = "SELECT DISTINCT i.ID, i.INSTANCE_ID, i.REGION, i.CNAME_STACK_ID, i.INSTANCE_STATE, i.IP_ADDRESS, i.EC2_ROLE_NAME, i.INSTANCE_OWNER, i.IS_MASTER, i.EC2_MASTER_ID, i.CNAME, i.EC2_START_TIMESTAMP, i.PRIVATE_DNS, i.INSTANCE_NAME, i.AUTO_TERMINATE, i.AUTO_TERMINATE_DATE, i.TERMINATION_ZONE, i.ADMIN_GROUP_AD_LDAP_ID, i.USER_GROUP_AD_LDAP_ID, (CASE WHEN i.INSTANCE_OWNER=:username THEN 'OWNER' WHEN i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) THEN 'ADMIN' WHEN i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) THEN 'USER' END) as PERMISSION FROM USER u, USER_ACCESS_GROUPS g, EC2_PROVISIONING i WHERE i.INSTANCE_OWNER=:username and i.INSTANCE_STATE in (:instanceStates) or u.username=:username and i.INSTANCE_STATE in (:instanceStates) and g.USER_ID=u.USER_ID and (i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) or i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID))",
countQuery = "SELECT count(*) FROM (SELECT DISTINCT i.* FROM USER u, USER_ACCESS_GROUPS g, EC2_PROVISIONING i WHERE i.INSTANCE_OWNER=:username and i.INSTANCE_STATE in (:instanceStates) or u.username=:username and i.INSTANCE_STATE in (:instanceStates) and g.USER_ID=u.USER_ID and (i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) or i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID))) as ug",
nativeQuery = true)
Page<Ec2Instance> findAllByPermissionUserAdminOrOwnerAndInstanceStateIn(
#Param("username")final String username,
#Param("instanceStates") final Set<String> instanceStates,
final Pageable pageable);
}
Obviously a bit more complex.
I can get it to map to the entity field with using a named query, but then I loose all the default mappings:
#JsonInclude(JsonInclude.Include.NON_NULL)
#SuppressWarnings("unused")
#Data
#AllArgsConstructor
#NoArgsConstructor
#EqualsAndHashCode(exclude={"masterNode", "workers", "associatedBuckets"})
#Entity
#Table(name = "EC2_PROVISIONING")
#SqlResultSetMapping(
name="listPagedMapping",
columns = {
#ColumnResult(name = "permission", type = String.class)
}
)
#NamedNativeQuery(
name = "listAccessibleInstances",
query = ACCESSIBLE_QUERY,
resultSetMapping = "listPagedMapping"
)
public class Ec2Instance {
....
private String permission;
#column(name = "INSTANCE_ID")
private String instanceId;
#ManyToOne
#JoinColumn(name = "EC2_MASTER_ID")
private Ec2Instance masterNode;
#Setter(AccessLevel.NONE)
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "WORKER_EC2_NODES", joinColumns = { #JoinColumn(name = "EC2_MASTER_ID") }, inverseJoinColumns = {
#JoinColumn(name = "ID") })
private Set<Ec2Instance> workers = new HashSet<>();
... More fields ..
}
I guess, I am hoping there is a way to provide a single mapping on-top of the default mapping that is done by ORM. The above code results in only a pageable of Content PERMISSION, rather than the whole entity + permission.
UPDATE: 2
Ok, so I am getting closer... Seems by removing the #ColumnResult I do get the default mapping, plus the PERMISSION field mapped over! Looks like this:
#SqlResultSetMapping(
name="listPagedMapping"
)
The last issue is it does not accept my CountQuery, and causes my tests to fail whenever a Pagination Query results with multiple pages. Looks like Spring try's to come up with its own CountQuery, which is not correct.
UPDATE: 3
To finish this off, looks like I can provide the Count Query as described here: Spring Data - Why it's not possible to have paging with native query
I will give this a go and update back.
I never got this to work quite how I wanted. I am sure I could by mapping my entire entity, but, that would have been painstaking. I ended up solving this by using NamedNativeQueries, with mapping for the additional Column as a result of my Case statement. My entity class is now annotated like:
#JsonInclude(JsonInclude.Include.NON_NULL)
#SuppressWarnings("unused")
#Data
#AllArgsConstructor
#NoArgsConstructor
#EqualsAndHashCode(callSuper = false)
#Entity
#Table(name = "EC2_PROVISIONING")
#SqlResultSetMappings({
#SqlResultSetMapping(
name = "listPagedMapping",
entities = {
#EntityResult(
entityClass = Ec2Instance.class
)
},
columns = {#ColumnResult(name = "permission", type = String.class)}
),
#SqlResultSetMapping(name = "listPagedMapping.count", columns = #ColumnResult(name = "cnt"))
})
#NamedNativeQueries({
#NamedNativeQuery(
name = "Ec2Instance.listAccessibleInstances",
query = ACCESSIBLE_QUERY,
resultClass = Ec2Instance.class,
resultSetMapping = "listPagedMapping"
),
#NamedNativeQuery(
name = "Ec2Instance.listAccessibleInstances.count",
resultSetMapping = "listPagedMapping.count",
query = ACCESSIBLE_QUERY_COUNT
)
})
We also dont need the permission field in this entity anymore. I removed that.
Then in my Repository:
Page<Object[]> listAccessibleInstances(
#Param("username")final String username,
#Param("instanceStates") final Set<String> instanceStates,
final Pageable pageable);
Thats it! Now the result of my case statement is returned with each entity.
Object[0] = original, default mapped entity.
Object[1] = permission
i have table named gifts that contains field company_value_id and i want to make select for all company_value_id,count(company_value_id) so that the result will be list of object and each object will contain company_value_id,count(company_value_id)
i am using spring jpa with annotations as follows:
public interface GiftsRepository extends JpaRepository<Gifts, String> {
#Query("from Gifts g where g.companyGuid = :companyGuid")
List<Gifts> getGiftsByCompany(#Param("companyGuid") String companyGuid);
}
please advise, thanks.
i was able to accomplish it as follows:
#Query("select g.value.id,cr.value.name,count(g.value.id) from Gift g where g.user.id=:userId group by g.value")
List<Object[]> getUserGifts(
#Param("userId") String userId);
and in the service layer i extract the values as follows:
List<Object[]> results = giftsRepository
.getUserGifts(userId);
for (Object[] result : results) {
String id = (String) result[0];
String name = (String) result[1];
int count = ((Number) result[2]).intValue();
}
You need add a parameter to your function,just like this:
#Query("from Gifts g where g.companyGuid = :companyGuid")
List<Gifts> getGiftsByCompany(#Param("companyGuid") String companyGuid,Pageable pageable);
and the pageabel can be create like this:
Pageable pageable = new PageRequest(pageIndex, pageSize, Direction.ASC, sortColumn);
