查詢3d信息（組3、組6、機球號）---存儲過程的使用方法---

1、存儲過程代碼：pr_get_3dinfo------------------

 

create or replace procedure pr_get_3dinfo(
                             iz3    in  integer,      --------組三 爲選默認0
                             iz6    in  integer,     --------組六
                             ijq       in  integer,     --------機球好
                             izjq     in  integer,        -----最近期數
                             iyear    in varchar2,      --------年份
                             ocursor out pk_public.zhcw_cursor   -------------遊標集
                            )

  is                 ---------在is 和begin 直接用來定義本地的臨時變量
    v_where varchar2(1000);    --------定義臨時變量（作爲動態的sql串中的條件變量串）
    v_sql varchar2(4000);          --------定義臨時變量（作爲動態的sql串）

    
    /*
   功能：
     參數：未選 默認0，
         iz3     1表示選中
         iz6    1表示選中
         ijq       1 1機1球 ，2 1機2球 ，3 2機1球， 4 2機2球
         izjq      ----最近期數
         iyear    --------年份

二、java 調用存儲過程。

  */
 public List find_3d_infor() throws Exception{
  

//創建一個連接對象
  Connection conn = getSession().connection();  
  //定義需要返回的List對象
  List list = new ArrayList();
  //定義阿帕奇提供的一個數據集對象
  RowSetDynaClass result = null;

//定義結果集對象

 ResultSet rs = null;

//定義數據連接控制對象
  CallableStatement proc = null;
 

  proc = conn.prepareCall("{ call pr_get_3dinfo(?,?,?,?,?,?) }");
  //設置整形和字符串型的數據
  proc.setInt(1, 0);
  proc.setInt(2, 0);
  proc.setInt(3, 0);
  proc.setInt(4, 30);
  proc.setString(5, "0");

  //定義需要返回的遊標參數
  proc.registerOutParameter(6, oracle.jdbc.OracleTypes.CURSOR);
  //執行數據
  proc.execute();

  //得到要返回的遊標數據
  rs = (ResultSet) proc.getObject(6);

  //將結果集轉換成需要的數據集對象
  result = new RowSetDynaClass(rs);

  list=result.getRows();
  //關閉結果集
