My native query -
interface PodcastRepository: JpaRepository<Podcast, Long> {
#Query(value = "SELECT new com.krtkush.sample.modules.podcast.models.PodcastDTO" +
"(p.id, p.author, p.title, p.description c.name, c2.name) " +
"AS sub_category_name FROM podcasts p " +
"LEFT JOIN categories c ON p.podcast_category_id = c.category_id " +
"LEFT JOIN categories c2 ON p.podcast_subcategory_id = c2.category_id " +
"WHERE p.podcast_owner = :ownerId", nativeQuery = true)
fun getPodcastsByOwner(#Param("ownerId")owner: Long): List<PodcastDTO>
}
However, when I execute the function I get the following error -
org.postgresql.util.PSQLException: ERROR: syntax error at or near "." Position: 15
position 15 is . after SELECT new com
I'm following this tutorial - https://smarterco.de/spring-data-jpa-query-result-to-dto/
The difference is that I'm using SQL rather than JPQL.

Im trying to avoid using native query. I have this query that uses the filter function, how could I rewrite this to not use that and work in regular jpql?
#Query(
"SELECT time_bucket(make_interval(:intervalType), d.time) as groupedDate, " +
"CAST(d.team_Id as varchar) as teamId, CAST(d.service_Id as varchar) as serviceId, CAST(d.work_id as varchar) as workId, " +
"ROUND(CAST(count(d.value) filter ( where d.type = 'A') AS numeric) /" +
" (CAST(count(d.value) filter ( where d.type = 'B') AS numeric)), 4) as total " +
"FROM datapoint d " +
"WHERE d.team_Id = :teamId and d.service_id in :serviceIds and d.work_id = :workspaceId and d.type in ('A', 'B') " +
"AND d.time > :startDate " +
"GROUP BY groupedDate, d.team_Id, d.service_Id, d.workspace_Id " +
"ORDER BY groupedDate DESC",
nativeQuery = true
)
in the FROM statement you have to use the DAO object instead of the table name
I have this query, which I have tried in SQL and it goes perfectly
#Query("SELECT new es.abacor.elser.commons.empleado.EmpleadoList("+
"empleado.id,persona.nombre,persona.apellido1,persona.apellido2,persona.dni,persona.email)" +
" FROM rrhh.empleado as empleado" +
" INNER JOIN commons.persona AS persona ON empleado.persona_comun = persona.id" +
" WHERE" +
" empleado.persona_comun is not null" +
" and empleado.borrador = false" +
" and empleado.deleted is null" +
" and empleado.fecha_fin_contrato is null" +
" order by persona.nombre,persona.apellido1,persona.apellido2 asc")
public List<EmpleadoList> allEmpleadosList();
But I get the following error when executing within my project
Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: ON near line 1, column 217 [SELECT new es.abacor.elser.commons.empleado.EmpleadoList(empleado.id,persona.nombre,persona.apellido1,persona.apellido2,persona.dni,persona.email) FROM rrhh.empleado as empleado INNER JOIN commons.persona AS persona ON empleado.persona_comun = persona.id WHERE empleado.persona_comun is not null and empleado.borrador = false and empleado.deleted is null and empleado.fecha_fin_contrato is null order by persona.nombre,persona.apellido1,persona.apellido2 asc]
Someone knows what I'm doing wrong, I do not know what to do anymore.
JPA doesn't work on tables, it works on objects. If you want to use native queries you have to add nativeQuery=true to the Definition:
#Query(nativeQuery=true, <SQL-Statement>)
otherwise the ON clasue will be generated from the annotations in your entities
I have the following Postgres SQL query, in order to get alerts with the latest date:
SELECT latest_alerts.subject_id,
latest_alerts.alertconfiguration_id_id,
latest_alerts.alert_level,
latest_alerts.maxdate
FROM (SELECT subject_id,
alertconfiguration_id_id,
alert_level,
Max(date) AS maxdate
FROM alert
WHERE subject_id IN ( 'da157532-8de5-4c0c-8608-d924e670d5db', '63b99886-77c8-4784-b8f0-7ff5310f1272' )
AND alertconfiguration_id_id IN (
'6feb6b8b-6b96-4d5d-ac58-713b3cd637a0'
)
GROUP BY subject_id,
alertconfiguration_id_id,
alert_level) AS latest_alerts
INNER JOIN alert
ON alert.date = latest_alerts.maxdate
AND alert.subject_id = latest_alerts.subject_id
AND alert.alertconfiguration_id_id =
latest_alerts.alertconfiguration_id_id
AND alert.alert_level IN ( 'WARNING' )
ORDER BY latest_alerts.maxdate DESC;
This runs well on the postgres database generated by Hibernate. Note the odd id_id construction is because of an embedded key.
But I'm struggling to transform this into a JPA/JPQL query that I can use in a Spring Boot application. So far I have this:
#Query("SELECT" +
" latest_alerts.subject," +
" latest_alerts.alertConfiguration," +
" latest_alerts.alertLevel," +
" latest_alerts.max_date" +
"FROM" +
" (SELECT" +
" subject," +
" alertConfiguration," +
" alertLevel," +
" MAX(date) AS max_date" +
" FROM" +
" alert" +
" WHERE" +
" subject.id IN (:subjectIds) AND alertConfiguration.id.id IN (:alertConfigurationIds)" +
" GROUP BY" +
" subject, alertConfiguration, alertLevel) AS latest_alerts" +
" INNER JOIN" +
" alert" +
" ON" +
" alert.date = latest_alerts.max_date" +
" AND alert.subject = latest_alerts.subject" +
" AND alert.alertConfiguration = latest_alerts.alertConfiguration" +
" AND alert.alertlevel IN (:alertLevels)" +
" ORDER BY latest_alerts.date DESC")
Page<Alert> findLatest(#Param("subjectIds") List<UUID> subjectIds,
#Param("alertConfigurationIds") List<UUID> alertConfigurationIds,
#Param("alertLevels") List<AlertLevel> alertLevels,
Pageable pageable);
But Hibernate doesn't understand what to do with this to the point where it actually throws a nullpointer while parsing this query.
Caused by: java.lang.IllegalArgumentException: Validation failed for query for method public abstract org.springframework.data.domain.Page ournamespace.sense.repository.AlertRepository.findLatest(java.util.List,java.util.List,java.util.List,org.springframework.data.domain.Pageable)!

at org.hibernate.hql.internal.antlr.HqlBaseParser.atom(HqlBaseParser.java:3549)
Any idea if this kind of query is even possible? With a nullpointer thrown by Hibernate it's a bit hard to see what part of the query is the problem.
Cannot do it with Hibernate. From the documentation:
Note that HQL subqueries can occur only in the select or where
clauses.
But you can use native query:
#Query(
value = "SELECT latest_alerts.subject_id,
latest_alerts.alertconfiguration_id_id,
latest_alerts.alert_level,
latest_alerts.maxdate ...
FROM ...",
nativeQuery = true)
Page<Alert> findLatest(#Param("subjectIds") List<UUID> subjectIds,
#Param("alertConfigurationIds") List<UUID> alertConfigurationIds,
#Param("alertLevels") List<AlertLevel> alertLevels,
Pageable pageable);
I'm trying to use this query in my jpa but it doesn't work:
List<Object[]> query = em.createQuery("SELECT Tstat.idStatistiques, TL.codeLieu, TL.materiel, TL.zone, sum(Tstat.colis) as colis, Tstat.defaut, sum(Tstat.nbreDefaut) as nbreDefaut,"
+ " sum(Tstat.nonLu) as nonLu, sum(Tstat.multiple) as multiple, sum(Tstat.nonRecu) as nonRecu, sum(Tstat.incoherent) as incoherent, sum(Tstat.requete) as requete , "
+ "sum(Tstat.tempsFonctionnement) as tempsFonctionnement, SUM(Tstat.tempsUtilisation) as tempsUtilisation, Tstat.modeFonctionnement FROM "
+ "( SELECT CURRENT_DATE as horodatage, St.idStatistiques, St.colis, St.defaut, St.nbreDefaut, St.nonLu, St.requete, St.multiple, St.nonRecu, St.incoherent, St.tempsFonctionnement, St.tempsUtilisation, St.modeFonctionnement FROM Statistique St )"
+ " UNION "
+ "(SELECT h.horodatage, h.idStatistiques, h.colis, h.defaut, h.nbreDefaut, h.nonLu, h.nonRecu, h.requete, h.multiple, h.incoherent, h.tempsFonctionnement, h.tempsUtilisation, h.modeFonctionnement FROM Statistiqueshisto h )"
+ " Tstat "
+ "LEFT JOIN (SELECT * FROM Lieux) as TL on Tstat.idStatistiques = TL.code_VI WHERE idStatistiques like :A ").setParameter("A", 0040+"%").getResultList();
This gives me error
The expression is invalid, which means it does not follow the JPQL
grammar.
I'm getting an exception error saying missing operators can anyone help
string sql = "Select SalesPerson.Name, Item.Description, Orders.Quantity, Orders.OrderDate"
+ "From([Orders]"
+ "Inner Join[SalesPerson] On Orders.SalesPersonID=SalesPerson.SalesPersonID)"
+ "Inner Join[Item] On Orders.ItemNumber=Item.ItemNumber"
+ "Where Orders.CustomerID=#customer Order by Orders.OrderDate DESC";
You need to add some spaces at the end of each of your lines of SQL!
string sql = "SELECT SalesPerson.Name, Item.Description, Orders.Quantity, Orders.OrderDate "
+ "FROM [Orders] "
+ "INNER JOIN [SalesPerson] ON Orders.SalesPersonID = SalesPerson.SalesPersonID "
+ "INNER JOIN [Item] ON Orders.ItemNumber = Item.ItemNumber "
+ "WHERE Orders.CustomerID = #customer "
+ "ORDER BY Orders.OrderDate DESC";
Otherwise, your SQL ends up being
Select ..... Orders.OrderDateFROM([Orders]Inner Join[SalesPerson] .....
and so on - and that's just not valid SQL.
I also removed some unnecessary parenthesis around the JOIN operators - those are only needed for MS Access, but since you're saying you're using ADO.NET, I assume this is not for MS Access and therefore, those parenthesis are not needed
