I have problem with my #Repository:
#Repository
public interface RekvZmRepository extends CrudRepository<RekvalZamestn, RekvalZamestnPk> {
#Query(value = "SELECT z.* FROM rek_zm d INNER JOIN proj_a a ON d.id = a.prj_idcislo"
+ " INNER JOIN proj_e e ON a.id = e.id"
+ " INNER JOIN rekv_z z ON d.id = z.id"
+ "WHERE d.id = ?1 AND a.id = ?2 AND e.id = ?3", nativeQuery = true)
public List<RekvalZamestn> getRekvOsOnDoh(Long dhzmrk, Long prj, Long prje);
}
When I run it, result is:
org.springframework.dao.InvalidDataAccessResourceUsageException: could not
extract ResultSet; SQL [n/a]; nested exception is
org.hibernate.exception.SQLGrammarException: could not extract ResultSet
When I run SQL it works, so for me it looks like problem is not with SQL but with my #Query.
Your query, in one-line format (condensing multiple spaces to one space for reasons of, erm, space), equates to
SELECT z.* FROM rek_zm d INNER JOIN proj_a a ON d.id = a.prj_idcislo INNER JOIN proj_e e ON a.id = e.id INNER JOIN rekv_z z ON d.id = z.idWHERE d.id = ?1 AND a.id = ?2 AND e.id = ?3
If you concatenate all the strings in one line like this, it becomes obvious that you are missing a space before the WHERE clause.
change SELECT z.* FROM to SELECT z FROM assuming RekvalZamestn class maps to table rekv_z.

I want to make a distinct select in my table with pagination, but it is claiming this error. Does anyone know how to solve it?
org.postgresql.util.PSQLException: ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list
#Query(value = "SELECT DISTINCT budget.* FROM budget LEFT JOIN user_budget ON budget.id = user_budget.budget_id ORDER BY budget.created DESC, ?#{#pageable}",
countQuery = "SELECT DISTINCT count(*) FROM budget LEFT JOIN user_budget ON budget.id = user_budget.budget_id",
nativeQuery = true)
public Page<Budget> findAllByfilter(Pageable pageable);
Currently i'm using PostgreSQL database in my Spring MVC web application. I'm able to get the values when i execute the query in PgAdmin tool.
In my query, I'm trying to join 4 tables and get the values.
My query is:
SELECT (s.school_id, u.first_name, u.last_name, u.username, u.email, p.plan_name, s.start_date, s.end_date, s.subscription_price, (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'T' and t.school_id = s.school_id), (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'A' and t.school_id = s.school_id), (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'S' and t.school_id = s.school_id)) FROM school s inner join user u on s.user_created = u.user_id inner join plan p on s.current_plan = p.plan_Id where s.application_id = 30 and s.site_id = 42;
When I use this same query in my Dao method, I'm getting error like:
No Dialect mapping for JDBC type: 1111
Code used in dao method:
public List<Object[]> getInformationValues(int applicationId, int siteId) throws HibernateException {
Session session = getCurrentSession();
Query query = session.createSQLQuery("SELECT (s.school_id, u.first_name, u.last_name, u.username, u.email, p.plan_name, s.start_date, s.end_date, s.subscription_price, (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'T' and t.school_id = s.school_id), (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'A' and t.school_id = s.school_id), (SELECT COUNT(*) FROM school_user t WHERE t.user_type = 'S' and t.school_id = s.school_id)) FROM school s inner join user u on (s.user_created = u.user_id) inner join plan p on (s.current_plan = p.plan_Id) where s.application_id = :applicationId and s.site_id = :siteId") .setParameter("applicationId", applicationId) .setParameter("siteId", siteId);
List<Object[]> results = query.list();
return results;
}
Is there any way to fix this issue?
I keep getting errors when trying to get this SQL correct for a JPA repository delete. What is the correct syntax?
#Query("delete * from TS t inner join TSC c ON t.tenantId = c.id where t.id= ?1 AND c.endDate < ?2")
void deleteTSWithExpiredDate(Long id, Date date);
Caused by: java.lang.IllegalArgumentException: node to traverse cannot be null!
at org.hibernate.hql.internal.ast.util.NodeTraverser.traverseDepthFirst(NodeTraverser.java:63)
Another
#Query("delete t.* from TS t inner join TSC c ON t.tenantId = c.id where t.id= ?1 AND c.endDate < ?2")
void deleteTSWithExpiredDate(Long id, Date date);
expecting IDENT, found '*' near line 1, column 10 [delete t.*
Another
#Query("delete t from TS t inner join TSC c ON t.tenantId = c.id where t.id= ?1 AND c.endDate < ?2")
void deleteTSWithExpiredDate(Long id, Date date);
unexpected token: from near line 1, column 10 [delete t
The syntax for bulk delete is:
Query q = session.createQuery("delete Entity where id = :idParam");
// set params here
q.executeUpdate();
However from Hibernate documentation, no joins can be specified in a bulk HQL query. Sub-queries can be used in the where-clause, where the sub-queries themselves can contain joins.
I need get all data from relative table so I'm using something like this (i would use it in sql)
private static final String SELECT_OOPR_TO_SEND = "SELECT R.* " +
"FROM offerOrderProjectRel R, offerOrder O, project P " +
"WHERE P.id = R.project_id and O.id = R.offer_order_id " +
"and O.type = 'ORDER' and (P.status = 'PENDING' or P.status ='PROTECTED')" ;
;
#SuppressWarnings("unchecked")
public List<OfferOrderProjectRel> findAllOfferOrderToSendToSalesmans() {
Query q = getSession().createQuery(SELECT_OOPR_TO_SEND);
List<OfferOrderProjectRel> list = q.list();
return list;
}
After lauching this code i'm getting that error :
org.hibernate.hql.internal.ast.QuerySyntaxException: expecting IDENT,
found '**' near line 1, column 10 [SELECT R.* FROM offerOrderProjectRel
R, offerOrder O, project P WHERE P.id = R.project_id and O.id =
R.offer_order_id and O.type = 'ORDER' and (P.status = 'PENDING' or
P.status ='PROTECTED')]
So how can I obtain all data from column R with hibernate?
The method createQuery expects an HQL query string.
HQL is an object-oriented querying language.
HQL interprets SELECT R.* as select the member field * of the object R.
But * is not a member field of R. Is it?..
To select all the member fields of R use:
SELECT R
FROM offerOrderProjectRel R, offerOrder O, project P
WHERE P.id = R.project_id and O.id = R.offer_order_id
and O.type = 'ORDER' and (P.status = 'PENDING' or P.status ='PROTECTED')
you use SQL query, not hql query, so it should be
Query q = getSession().createSQLQuery(SELECT_OOPR_TO_SEND);
For people that received the "expecting IDENT found “*”" error when using org.springframework.data.jpa.repository.Query and found this question I'll add that you can change the nativeQuery flag to true:
#Query(value = "SELECT * FROM table1", nativeQuery = true)
List<Object> myFindAll();
I have a sql query:
select * from A
INNER JOIN B
ON A.id = B.id
INNER JOIN C
ON B.id = C.id
INNER JOIN D
ON C.id = D.id
where D.name = 'XYZ'
and D.Sex = 'M'
I have been trying to come with hibernate query criteria for the above sql, but having problems. Could anybody help out.
Criteria c = session.createCriteria(A.class, "a");
.createAlias("a.b", "b")
.createAlias("b.c", "c")
.createAlias("c.d", "d")
.add(Restrictions.eq("d.sex", "M"))
.add(Restrictions.eq("d.name", "XYZ"));
On your question you want to perform a Cartesian Join, and this is not supported by Criteria, although you can do it with HQL as show below. There is a similar question here
With HQL query you could do something like:
select a from
A a,
B b,
C c
where
a.id = b.id and
c.id = b.id and
d.id = c.id and
d.name = 'XYZ' and
d.sex = 'M'
The query is used in a regular hibernate query:
Query query = session.createQuery(query); // <-- here you use the query above
List results = query.list();
