iBatis学习四之删除指定id的单个对象

1、实现IStudentDAOImp类中的deleteStudentById()，如下：

@Override
public int deleteStudentById(int id) {
	int i = 0;
	try {
		i = sqlMapClient.delete("deleteStudentById", id);
	} catch (SQLException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	return i;
}

 

2、在Student.xml文件中添加上，如下的代码：

<delete id="deleteStudentById" parameterClass="int">delete from student where sid = #sid#</delete>

 

3、main()调用deleteStudentById()测试
