hibernate update-->參數綁定

Hibernate 更新數據庫 參數綁定總結：

一.query.setParameter(屬性名，真實值，類型）;

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

Query query  = getSession.createQuery(hql); 

query.setParameter("userName", userName(對應:後面的值), Hibernate.STRING);

query.setParameter("userId", userId(對應:後面的值), Hibernate.INTEGER);

query.executeUpdate();

二.query.setXXXX(屬性值,真實值);

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(問號位置,真實值);

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(對象);

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

Query query  = getSession.createQuery(hql); 

User user = new User();

user.serUserName("張三");

user.setUserId(2);

query.setProperties(user);

query.executeUpdate();
