表对应的实体类是TblUser,下列HQL 语句中正确的是

TblUser t where = "15"
,要输出查询结果中第一条记录的用户名,正确的代码是(AD )。
String hql = "select , from TblUser u";
Query query = (hql);
[] arr = (Object[])().iterator().next();
(arr[0]);
user = (TblUser)().get(0);
(());
uname = (String)().get(0).get(0);
(uname);
uname = (String)().get(0)[0];
(uname);
,说法不正确的是( D)。
String hql = "from TblUser u where = ***@status ";//<1>
Query query = ();//<2>
(":status","");//<3>
return (hql);//<4>
“***@status”应该是“:status”
函数应该传入hql 作为参数
“:status”应该是“status”
“return (hql);”

String hql = "from TblStudent s order by asc";
Query query = (hql);
(0);
(5);

select stu
from TblStudent stu
where
