Question

I’m trying to call a PL/pgSQL function that executes an update (language sql, returns void). I’m getting this exception:

Internal Exception: org.postgresql.util.PSQLException: A result was returned when none was expected.

persistence.xml:

<named-native-query name="Clinic.deactivateByNotFoundInIncomingClinic">
    <query>
        <![CDATA[
            select apply_incoming_clinic_deletions(?)
        ]]>
    </query>
</named-native-query>

DAO:

public void deactivateByNotFoundInIncomingClinic(long clinicSystemId)
{
    em.createNamedQuery("Clinic.deactivateByNotFoundInIncomingClinic")
            .setParameter(1, clinicSystemId)
            .executeUpdate();
}

Help!

Update:

Using EclipeseLink on GlassFish 3.1.1 talking to PostgreSQL 9.0 database via PostgreSQL 9.0-801 JDBC 4 drivers.

Answer 1

Changing the DAO code to this worked:

public void deactivateByNotFoundInIncomingClinic(long clinicSystemId)
{
    em.createNamedQuery("Clinic.deactivateByNotFoundInIncomingClinic")
            .setParameter(1, clinicSystemId)
            .getSingleResult();
}
