JPA passing list to IN clause in named native query

Question

I know I can pass a list to named query in JPA, but how about NamedNativeQuery? I have tried many ways but still can\'t just pass the list to a NamedNativeQuery. Anyone know

Answer 1

In my case ( EclipseLink , PostGreSQL ) this works :

    ServerSession serverSession = this.entityManager.unwrap(ServerSession.class);
    Accessor accessor = serverSession.getAccessor();
    accessor.reestablishConnection(serverSession);
    BigDecimal result;
    try {
        Array jiraIssues = accessor.getConnection().createArrayOf("numeric", mandayWorkLogQueryModel.getJiraIssues().toArray());
        Query nativeQuery = this.entityManager.createNativeQuery(projectMandayWorkLogQueryProvider.provide(mandayWorkLogQueryModel));
        nativeQuery.setParameter(1,mandayWorkLogQueryModel.getPsymbol());
        nativeQuery.setParameter(2,jiraIssues);
        nativeQuery.setParameter(3,mandayWorkLogQueryModel.getFrom());
        nativeQuery.setParameter(4,mandayWorkLogQueryModel.getTo());
        result = (BigDecimal) nativeQuery.getSingleResult();
    } catch (Exception e) {
        throw new DataAccessException(e);
    }

    return result;

Also in query cannot use IN(?) because you will get error like :

Caused by: org.postgresql.util.PSQLException: ERROR: operator does not exist: numeric = numeric[]

'IN(?)' must be swapped to '= ANY(?)'

My solution was based on Erhannis concept.
