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
