JDBC与Hibernate中SQL语句参数设置的顺序问题

JDBC中:设置从1开始

例:

Connection con = DriverManager.getConnection("jdbc:mysql://localhost/...","root","123");

String sql = "insert into t_user values (?,?,?)";

PreparedStatment ps = con.prepared(sql);

ps.setString(1,"...");

ps.setString(2,"...");

ps.setString(3,"...");

Hibernate中:设置从0开始

例:

String hql = "from User user where user.id=? and user.username=? ";

Query q = sessionFactory.getCurrentSession.createQuery(hql);

q.setParameter(0,"...");

q.setParameter(1,"...");

PS:Hibernate推荐使用?加字符串识别的方式设置参数

例:

String hql = "from User user where user.id=?id and user.username=?username ";

Query q = sessionFactory.getCurrentSession.createQuery(hql);

q.setParameter("id","...");

q.setParameter("username","...");
