Answer 1

Hibernate 支持连接限制，但语法与 SQL 不同。您必须在 Hibernate中替换ON关键字！WITH

Answer 2

Chetter Hummin 是对的，HQL 不支持“开”。看到这个：http ://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html

Answer 3

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 orders 表中的一列。
