4 ibatis2.0与ibatis3.0 调用存储过程(SQL)
http://blog.sina.com.cn/s/blog_62e744e60100olfr.html

对于MyIbatis调用存储过程的一个特点是:使用Map传递参数
此示例是在前二个MyIbatis示例基础之上得来的

一 环境:XP3+Oracle10g+MyEclipse6+(Tomcat)+JDK1.5

二 Oracle存储过程

1 添加用户

create or replace procedure addUser(u_id in varchar2,u_name in varchar2,u_age in integer,u_sex in varchar2,u_address in varchar2,u_pwd in varchar2,message out varchar2) is
  begin
     insert into users (id,name,age,sex,address,password)VALUES(u_id,u_name,u_age,u_sex,u_address,u_pwd);
      message := '插入用户表成功';
     commit;    
  EXCEPTION
  WHEN OTHERS THEN
  message :='插入用户表失败';
end addUser;

2 修改用户

create or replace procedure updateUser(u_id in varchar2,u_name in varchar2,u_age in integer,u_sex in varchar2,u_address in varchar2,u_pwd in varchar2,message out varchar2) is
  begin
     update users u set name=u_name,age=u_age,sex=u_sex,address=u_address,password=u_pwd where id=u_id;
      message := '更新用户表成功';
     commit;
  EXCEPTION
  WHEN OTHERS THEN
  message :='更新用户表失败';
end updateUser;

3 删除用户

create or replace procedure delUser(u_id in varchar2,message out varchar2) is
  begin
     delete users  where id=u_id;
      message := '删除用户表成功';
     commit;
  EXCEPTION
  WHEN OTHERS THEN
  message :='删除用户表失败';
end delUser;

4 查询用户

create or replace package JUV is  
  TYPE CUR_GETUSER IS REF CURSOR;   
end JUV;

create or replace procedure getAllUser(userList out JUV.CUR_GETUSER)
as
begin
open userList for select * from users;       
end getAllUser;

三 UserMapper.java

public interface UserMapper{
	
	public int checkUserExits(User user);		
	
	public void addUser(User user);		
	//测试存储过程插入
	public void addUserProc(Map user);
	public List<User> getAllUser(Map map);	
	public void selectByProc(Map<String,Integer> p);	
	public void editUserProc(Map map);
	public void delUserProc(Map map);
	public void testCounts(Map map);
}

四 映射文件

查询好像不行 返回值为空
