Answer 1

Hibernate支持加入限制，但语法与SQL不同。您必须在Hibernate中将ON关键字替换为WITH！

Answer 2

productList = (List<Object[]>) session.createQuery("SELECT op.username, op.email, orders.p_id, orders.o_id, product.listed_price " + "FROM Orders  orders " +"INNER JOIN orders.OrderProcessing as op " +  "ON op.u_id = orders.u_id"+ "INNER JOIN orders.Product as product " + "ON product.p_id = orders.p_id "+ "WHERE product.p_id = '"+p_id +"'" "ORDER BY op.username").list();

您必须检查订单表。 orders.orderProcessing不是一个表，它是一个来自orders表的列。

Answer 3

Chetter Hummin是对的，HQL不支持“on”。 请参阅：http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html
