1、Ibatis实现增删改操作很简单了，通常我是将某一模块的增删改功能写在一个存储过程里，通过一个标识符去区分执行增加还是修改抑或删除操作。
statement：
<!-- 存储过程：实现学生的增删改操作 -->
<procedure id="crud" parameterClass="xuesheng" >
{call PRO_STUDENT_SUBMIT(
#xs_id#,
#xs_name#,
#zy_id#,
#xs_num#,
#xs_sfz#,
#xs_tel#,
#xs_email#,
#xs_address#,
#xs_sex#,
#xs_date#,
#bq#
)}
</procedure>
procedure：
create or replace procedure PRO_STUDENT_SUBMIT(
v_xs_id in varchar2,
v_xs_name in varchar2,
v_zy_id in varchar2,
v_xs_num in varchar2,
v_xs_sfz in varchar2,
v_xs_tel in varchar2,
v_xs_email in varchar2,
v_xs_address in varchar2,
v_xs_sex in varchar2,
v_xs_date in varchar2,
v_bq in varchar2
) is
begin
--当bq为1时，执行添加操作；为2时，执行修改操作；为3时执行删除操作
if (v_bq = '1') then
insert into xs
(xs_id, xs_name, zy_id, xs_num, xs_sfz, xs_tel, xs_email, xs_address, xs_sex,xs_date)
values
(seq_xs.nextval , v_xs_name, v_zy_id, v_xs_num, v_xs_sfz, v_xs_tel, v_xs_email, v_xs_address, v_xs_sex,v_xs_date);
end if;
if (v_bq = '2') then
update xs
set xs_id = v_xs_id,
xs_name = v_xs_name,
zy_id = v_zy_id,
xs_num = v_xs_num,
xs_sfz = v_xs_sfz,
xs_tel = v_xs_tel,
xs_email = v_xs_email,
xs_address = v_xs_address,
xs_sex = v_xs_sex,
xs_date=v_xs_date
where xs_id = v_xs_id;
end if;
if (v_bq = '3') then
delete xs
where xs_id = v_xs_id;
end if;
end PRO_STUDENT_SUBMIT;
2、重要要说的是通过ibatis调用存储过程实现分页查询（带模糊查询），我们需要有一个返回参数，该参数是游标类型。
通过调用存储过程实现的分页查询要比上文介绍的ibatis分页查询性能上好很多。
代码实例如下（经测试完全好使，ibatis版本2.3）
/**
* 在存储过程内实现查询的分页 与 模糊查询
* 需要传入到存储过程的参数 模糊查询的包括 学生姓名 学号 性别 入学时间的起止两个时间 一共5个
* 分页需要的参数 那就是 pageNo pageSize 一共2个 总共需要7个IN参数 返回的肯定是游标了 所以有一个OUT 类型的 CURSOR;
* 这些IN 参数都可以通过page对象传过去
*/
public String queryByPro (){
((XueShengPage)page).setXs_name(xs.getXs_name());
((XueShengPage)page).setXs_num(xs.getXs_num());
((XueShengPage)page).setDateFrom(xs.getPage_dateFrom());
((XueShengPage)page).setDateTo(xs.getPage_dateTo());
((XueShengPage)page).setXs_sex(xs.getXs_sex());
Date nowMilDate = new Date();
long time1 = nowMilDate.getTime();
xsList=this.xsService.queryByPro((XueShengPage)page);
Date time2 = new Date();
LogUtil.info("存储过程实现分页查询用时："+(time2.getTime()-time1));
return "query";
}
public List queryByPro(XueShengPage page) {
int rowCount=this.dao.queryForInt("xuesheng.queryListCount", page);//查询总条数
page.setRowCount(rowCount);
page.accountPageCount();//计算总页数
List xsList=new ArrayList();
Map map1 = new HashMap();
map1.put("xs_name",page.getXs_name());
map1.put("xs_num", page.getXs_num());
map1.put("xs_sex", page.getXs_sex());
map1.put("dateFrom", page.getDateFrom());
map1.put("dateTo", page.getDateTo());
map1.put("pageNo", page.getPageNo());
map1.put("pageSize", page.getPageSize());
this.dao.queryOne("xuesheng.pro_cursor", map1);
List<Map> list=(List<Map>) map1.get("backcursor");//调用存储过程进行查询
for(int i=0;i<list.size();i++){
XueSheng xs=new XueSheng();//需要传递模糊查询 和 分页所需要的参数（页号pageNo和每页显示多少条pageSize）
xs.setXs_id(list.get(i).get("xs_id").toString());
