HQL是hibernate自己的一套查询语言，于SQL语法不同，具有跨数据库的优点。示例代码：
// 获取检查单实例列表
String tplSql = "FROM CheckFormTemplate t where t.type=-1 and t.id in("+ instanceIdStr +")";
Session session = getSession();
return session.createQuery(tplSql).list();
Long count = (Long) session.createQuery("select count(*) from CheckFormTemplate where type=-1").uniqueResult();
//传递参数
String result = (String) session .createQuery("select result from CheckFormTemplate where id=:id")
.setParameter("id", id)
.uniqueResult();
List list = session.createQuery("from CheckForm where dataId=:id order by checkItem,checkNote")
.setParameter("id", id)
.list();
//删除
session.createQuery("delete from DictEntity").executeUpdate();
String hql = "delete BasicDataObject where id = ‘" + id + "‘";
String sql = "delete from data_object_basic_old where id = ‘" + id
+ "‘ and owner_id = ‘" + ownerId + "‘";
try {
this.getHibernateSession().createQuery(hql).executeUpdate();
this.getHibernateSession().createSQLQuery(sql).executeUpdate();
//查询
//分页查询
//createSqlQuery查询
public QueryResult<TeachnicalAgreement> loadTeachData(Map<String, Object> param) {
StringBuffer sbSql = new StringBuffer();
sbSql.append("select T.ID \"id\",\n");
