1、查询所有的学生信息：
（1）查询结果中，一条信息放入到一个数组中，从list集合中取出数组，并对数组进行遍历。
public class GeneratorTest { public static void testSel() { Session session = HibernateUtils.openSession(); Transaction transaction = session.beginTransaction(); String sql="Select * from Student"; SQLQuery sqlQuery=session.createSQLQuery(sql); List<Object[]>list= sqlQuery.list(); for(Object[] objects:list){ System.out.println(Arrays.toString(objects)); } System.out.println(list); transaction.commit(); session.close(); }
（2）直接封装到学生对象中，将对象存储到list集合：
public static void testSel() { Session session = HibernateUtils.openSession(); Transaction transaction = session.beginTransaction(); String sql="Select * from Student"; SQLQuery sqlQuery=session.createSQLQuery(sql); sqlQuery.addEntity(Student.class); List<Student>list= sqlQuery.list(); System.out.println(list); transaction.commit(); session.close(); }
2、占位符的使用：
public static void testSel() { Session session = HibernateUtils.openSession(); Transaction transaction = session.beginTransaction(); String sql="Select * from Student where sex=?"; SQLQuery sqlQuery=session.createSQLQuery(sql); sqlQuery.setParameter(0,"女"); sqlQuery.addEntity(Student.class); List<Student>list= sqlQuery.list(); System.out.println(list); transaction.commit(); session.close(); }
3、分页查询：
public static void testSel() { Session session = HibernateUtils.openSession(); Transaction transaction = session.beginTransaction(); String sql="Select * from Student limit ?,?"; SQLQuery sqlQuery=session.createSQLQuery(sql); sqlQuery.setParameter(0,0); sqlQuery.setParameter(1,1); sqlQuery.addEntity(Student.class); List<Student>list= sqlQuery.list(); System.out.println(list); transaction.commit(); session.close(); }
