I have viewed some of the related question but the solutions on them are bit older. Most of them are using EntityManager. I have written the following native query in JpaRepository and when I get geojson as a String I'm getting the error mentioned in the title.
Here is my query
#Query(value = "SELECT\n"
+ " json_build_object(\n"
+ " 'type', 'FeatureCollection',\n"
+ " 'features', json_agg(\n"
+ " json_build_object(\n"
+ " 'type', 'Feature',\n"
+ " 'geometry', ST_AsGeoJSON(a.check_in_geom)\\:\\:json,\n"
+ " 'properties', json_build_object(\n"
+ " 'username', a.username,\n"
+ " 'users', (\n"
+ " -- Generate json array of \"users\"\n"
+ " SELECT array_to_json(array_agg(u.*)) \n"
+ " FROM users u \n"
+ " WHERE u.username = a.username\n"
+ " GROUP BY u.username\n"
+ " )\n"
+ " )\n"
+ " )\n"
+ " )\n"
+ " ) Json\n"
+ "FROM\n"
+ " attendances a, users u\n"
+ " WHERE a.username = u.username AND u.designation = 'Manager' AND date_trunc('day', a.created_at)\\:\\:DATE = '2022-04-04'"
+ " ;", nativeQuery = true)
String getAttendanceGeoJsonByDesignationAndDate(String designation, String dateStr);
For now I'm passing designation and date as static values.
When I run this query on Postgresql it runs successfully and return the expected geojson. But spring boot does not allow the result to be as String or it throws exception while running the query.
Please let me know how can I fix it. Also if I need to provide more detail, do let me know.

This is my code looks like
#Query(value = "SELECT pu.id_user AS idUser, " +
"pu.full_name AS \"name\", " +
"pu.username, " +
"pu.email, " +
"CASE pu.status " +
"WHEN 0 THEN 'Blocked' " +
"WHEN 1 THEN 'Unblocked' " +
"END status, " +
"(SELECT branch_name AS \"branch\" " +
"FROM schema_a.branch aa " +
"WHERE mpb.branch_id IS NOT NULL AND mpb.parent_branch_id IS NOT NULL AND " +
"branch_id = mpb.parent_branch_id " +
") AS branch, " +
"mpb.branch_id AS childId, " +
"mpb.branch_name AS childName, " +
"mpb.parent_branch_id AS parentBranchId, " +
"r.role_name AS roleName " +
"FROM schema_a.user pu " +
"JOIN schema_a.branch mpb ON pu.id_branch = mpb.id_branch " +
"JOIN schema_a.\"role\" r ON pu.id_role = r.id_role " +
"WHERE pu.is_deleted = false", nativeQuery = true)
Page<UserAndBranch> findAllByIsDeletedIsFalse(Pageable pageable);
the result i got
Caused by: org.postgresql.util.PSQLException: ERROR: missing FROM-clause entry for table "aa"
That native query is executed succesfully in DBeaver, nothings different just remove the quotation mark, what am I missing?
I'm trying to do the following code, but i get the unexpected token: : near line 1 error which refer to ord.date_out::date. Here is my code
#Query(value="select new com.ameerarestapi.wrapper.report.SummaryPeriodicSales(sto.name, sum(odi.subtotal_price), sum(odi.qty), ((sum(odi.subtotal_price))/(sum(odi.qty))), ord.date_out::date) "
+ "from OrderDetailItem odi "
+ "left join odi.order as ord "
+ "left join ord.store as sto "
+ "where ord.store.principle = :principle and ord.orderStatus IN :orderstatus and ord.dateOut between :date1 and :date2 and ord.voidStatus = :voidStatus "
+ "group by sto.name, ord.date_out::date ")
List<SummaryPeriodicSales> getReportDaily(#Param("principle") Principle principle,#Param("orderstatus") List<OrderStatus> orderstatus,#Param("date1") Date date1,#Param("date2") Date date2,#Param("voidStatus") byte voidStatus);
I'm using postgre database
Use the standard CAST() operator instead:
CAST(ord.date_out AS date)
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 have written a native query in jpa which fetch list of object array
list = entityManager.createNativeQuery("select emp.card Card,emp.code Code,emp.emp_name EmpName,ln.BAL Balance, ln.cum_intr CumIntr, ln.install Install,ln.install_no InstallNo, "
+ " led.BAL ledgBAL,led.cum_intr ledgCum,led.install ledgInstall,led.install_no ledgInstallNo "
+ " from LOANS ln "
+ " inner join "
+ " LOAN_LEDGER led "
+ " on (led.EMPLOYEES_ID = ln.EMPLOYEES_ID and ln.LOAN_UID= led.LOAN_UID and (ln.bal!= led.BAL or ln.cum_intr!= led.cum_intr or ln.INSTALL != led.INSTALL )) "
+ " inner join EMPLOYEES emp "
+ " on ln.employees_id = emp.id "
+ " where led.ledger_month in "
+ " ( 201312 )").getResultList();
I assigned alias for each field.this is my code to access this object array.
Iterator it = list.iterator();
while (it.hasNext()) {
Object[] result = (Object[]) it.next();
System.err.println("Result Arrayyyyy "+result[0]);
}
Now i want to access this result array using alias . How can I do it?
