Java Persistence SQL nativo non accettare parametri

Question

la mia domanda è

sql = "SELECT SUM(TOTAL_BYTES_DELIVERED)/SUM(TOTAL_TIME_TAKEN_IN_DELIVERY) 
     FROM MV_MFT_TRANSFER 
     WHERE TRANSFER_INITIATION_TIME > :startDate 
      AND TRANSFER_INITIATION_TIME < :endDate" 

Query query = em.createNativeQuery(sql); 
query.setParameter("startDate", startDate, TemporalType.DATE); 
query.setParameter("endDate", endDate, TemporalType.DATE); 
query.getResultList();' 

Quando eseguo questo, ottengo un errore

Answer 1

La seguente soluzione dovrebbe funzionare:

sql = "SELECT SUM(TOTAL_BYTES_DELIVERED)/SUM(TOTAL_TIME_TAKEN_IN_DELIVERY) 
     FROM MV_MFT_TRANSFER 
     WHERE TRANSFER_INITIATION_TIME > ? 
      AND TRANSFER_INITIATION_TIME < ?" 

Query query = em.createNativeQuery(sql); 
query.setParameter(1, startDate, TemporalType.DATE); 
query.setParameter(2, endDate, TemporalType.DATE); 
query.getResultList(); 

E ' sembra che se usi i parametri posizionali funzionerà. Non è possibile combinare parametri con nome e query nativa. Qui ci sono alcuni link:

http://java.boot.by/scbcd5-guide/ch08s05.html

http://www.wisegeek.com/what-are-native-queries.htm

E molti altri, solo Google per: "Solo parametro posizionale vincolante può essere portabile utilizzato per le query native".

Questo articolo è stato davvero utile!

http://software-security.sans.org/developer-how-to/fix-sql-injection-in-java-persistence-api-jpa

Il senso di questo articolo è:

Questi sono non sicuri query, non usarlo! La concatenazione di stringhe è male:

List results = entityManager.createQuery("Select order from Orders order where order.id = " + orderId).getResultList(); 
List results = entityManager.createNativeQuery("Select * from Books where author = " + author).getResultList(); 
int resultCode = entityManager.createNativeQuery("Delete from Cart where itemId = " + itemId).executeUpdate(); 

Questi sono sicuri query.

/* positional parameter in JPQL */ 
Query jpqlQuery = entityManager.createQuery("Select order from Orders order where order.id = ?1"); 
List results = jpqlQuery.setParameter(1, "123-ADB-567-QTWYTFDL").getResultList(); 

/* named parameter in JPQL */ 
Query jpqlQuery = entityManager.createQuery("Select emp from Employees emp where emp.incentive > :incentive"); 
List results = jpqlQuery.setParameter("incentive", new Long(10000)).getResultList(); 

/* named query in JPQL - Query named "myCart" being "Select c from Cart c where c.itemId = :itemId" */ 
Query jpqlQuery = entityManager.createNamedQuery("myCart"); 
List results = jpqlQuery.setParameter("itemId", "item-id-0001").getResultList(); 

/* Native SQL */ 
Query sqlQuery = entityManager.createNativeQuery("Select * from Books where author = ?", Book.class); 
List results = sqlQuery.setParameter(1, "Charles Dickens").getResultList();

In JPA

quando si utilizza questo: interrogazione

query = em. createNativeQuery (sql);

è necessario impostare l'indice per i parametri impostati. Si noti che la query ha più di un parametro.
