在Hibernate中使用HQL实现相同的结果

Question

我想用Hibernate HQL实现以下SQL查询：

select abc_id, count(*) from boa_rep_deed where sync_system = ? And hook_id = ? group by abc_id order by abc_id

现在我的问题是我也有相应的pojo，如下所示..

class teedObject{
    private long abcID ;
    private String syncSystem ;
    private String hookId;
    //and consisits other properties and setters and getters
}

我已实施以下标准..

Criteria cr = session.createCriteria(teedObject.class);
cr.add(Restrictions.eq("syncSystem", syncSystem));
cr.add(Restrictions.eq("hookId", hookId));
cr.addOrder(Order.asc("abcID"));
cr.add(Projections.groupProperty("abcID")));
cr.setProjection(Projections.rowCount());
hytlow = cr.list();

现在请告知我如何使用HQL实现相同目的 伙计们请指教

未经测试，但我想：

select x.abcId, count(x) 
from   teedObject as x 
where  x.syncSystem = :syncSystemParam And x.hookId = :hookIdParam 
group by x.abcId
order by x.abcId

HQL通常就像SQL一样，而列被属性和带有类的表替换，对应于映射。
