问题描述
我正在使用 hibernate 4.2.6
和 PostgreSQL 9.1
我一直在尝试用hibernate执行sql查询。我写过:
I'm using hibernate 4.2.6
and PostgreSQL 9.1
I've been trying to execute sql query with hibernate. I've written:
Session session = Hibernate.util.HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);", product.getName(), product.getCost());
createSQLQuery(sql);//has no effect. Query doesn't execute.
session.getTransaction().commit();
session.close();
此查询不在DB中执行。但如果我写了
This query does not executed in DB. But if I write
String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);", product.getName(), product.getCost());
Properties connectionProps = new Properties();
connectionProps.put("user", "postgres");
connectionProps.put("password", "123");
Connection conn = DriverManager.getConnection("jdbc:postgresql://localhost:5432/solid",connectionProps);
conn.createStatement().execute(sql);
相应的行将添加到表中。为什么hibernate不起作用,但JDBC的原生查询是否有效?
corresponding row will add to table. Why hibernate doesn't work, but native query wth JDBC works?
推荐答案
这应该可以帮到你。
Session session = Hibernate.util.HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);",product.getName(), product.getCost());
session.createSQLQuery(sql).executeUpdate();
session.getTransaction().commit();
session.close();
