<class name="com.sxyh.entity.TRoom" table="t_Room" schema="dbo" catalog="PrisonSecurity">

<sql-query name="proc" callable="true">
<return alias="Room" class="com.sxyh.entity.TRoom">

<return-property name="FNumber" column="FNumber" />
<return-property name="FName" column="FName" />

</return>
{call proc()}
</sql-query>

</hibernate-mapping>




执行方法
Session session =HibernateSessionFactory.getSession();
// SQLQuery query = session.createSQLQuery("{Call proc()}");
Query query = session.getNamedQuery("proc");

List list =query.list();
System.out.println("s=========="+list.size());
session.close();


结果关键字 'proc' 附近有语法错误。哪一步错了哪位大哥说下
