Hibernate执行原生的sql语句

1,可以通过session.cretaeSQLQuery().executeUpdate()。来执行。

如：public void insertDemo(final String name,final String password){
final String nm=getNM();
getHibernateTemplate().execute(new HibernateCallback(){

public Object doInHibernate(Session session)
throws HibernateException, SQLException {
// TODO Auto-generated method stub
String sql="insert into demo(nm,name,password) values('"+nm+"','"+name+"','"+password+"')";
SQLQuery sqlQuery=session.createSQLQuery(sql);
int num=sqlQuery.executeUpdate();
return null;
}

});
}

public void updateDemo(final String name,final String password){
Session session=getHibernateTemplate().getSessionFactory().getCurrentSession();
String sql="select nm from demo where name='"+name+"'";
SQLQuery sqlQuery=session.createSQLQuery(sql);
List list=sqlQuery.list();
final String nm=list.get(0).toString();
getHibernateTemplate().execute(new HibernateCallback(){

public Object doInHibernate(Session session)
throws HibernateException, SQLException {
// TODO Auto-generated method stub
String sql="update demo set name='"+name+"',password='"+password+"' where nm='"+nm+"'";
SQLQuery sqlQuery=session.createSQLQuery(sql);
int num=sqlQuery.executeUpdate();
return null;
}

});
}

public void deleteDemo(final String name,final String password){
getHibernateTemplate().execute(new HibernateCallback(){

public Object doInHibernate(Session session)
throws HibernateException, SQLException {
// TODO Auto-generated method stub
String sql="delete from demo where name='"+name+"' and password='"+password+"'";
SQLQuery sqlQuery=session.createSQLQuery(sql);
int num=sqlQuery.executeUpdate();
return null;
}

});
}

2 可以执行select to_char(sysdate,'yyyymmssHH24mmss') from dual来得到nm作为主键。

如：public  String getNM(){
String nm="";
nm=(String) getHibernateTemplate().execute(new HibernateCallback(){

public String doInHibernate(Session session)
throws HibernateException, SQLException {
// TODO Auto-generated method stub
String sql="select to_char(sysdate,'yyyymmssHH24mmss') from dual";
List list=session.createSQLQuery(sql).list();
String nm_new=list.get(0).toString();
return nm_new;
}

});
return nm;
}
