Answer 1

Use it. It's working

public class IncIncidentListGridModel
{

    private String historyStatus = null;

    public String getHistoryStatus()
    {
        return historyStatus;
    }

    public void setHistoryStatus(String historyStatus)
    {
        this.historyStatus = historyStatus;
    }

    public void run()
    {
        IncIncidentListGridModel resultCount =
            (IncIncidentListGridModel) ((SQLQuery) hibersession
                .createSQLQuery("select count(ch.incident_capa_history_id) as historyStatus  from incident_capa_history ch, incident_capa ic where ic.incident_capa_id = ch.FK_incident_capa_id and ic.incident_capa_id='011'"))
                .addScalar("historyStatus", Hibernate.STRING)
                .setResultTransformer(
                    Transformers.aliasToBean(IncIncidentListGridModel.class))
                .uniqueResult();

        System.out.println("count result" + resultCount.getHistoryStatus());
    }
}
