hibernate update-->参数绑定

Hibernate 更新数据库 参数绑定总结：

一.query.setParameter(属性名，真实值，类型）;

String hql="update User u set u.userName=:userName where u.userId=:userId";

Query query  = getSession.createQuery(hql);

query.setParameter("userName", userName(对应:后面的值), Hibernate.STRING);

query.setParameter("userId", userId(对应:后面的值), Hibernate.INTEGER);

query.executeUpdate();

二.query.setXXXX(属性值,真实值);

String hql="update
User u set u.userName=:userName where u.userId=:userId";

query.setString("userName",userName);

query.setInteger("userId",userId);

query.executeUpdate();

三.query.setString(问号位置,真实值);

String hql="update
User u set u.userName=?
where
u.userId=?";

Query query  = getSession.createQuery(hql);

query.setString(0,userName);

query.setInteger(1,userId);

query.executeUpdate();

四.query.setProperties(对象);

String hql="update User u set
u.userName=:userName where
u.userId=:userId";

Query query  = getSession.createQuery(hql);

User user = new User();

user.serUserName("张三");

user.setUserId(2);

query.setProperties(user);

query.executeUpdate();
