oracle返回多结果集

kavy 原文 oracle返回多结果集

Oracle存储过程：

create or replace procedure P_Sel_TopCount2(in_top    in number,

                                           out_count out number,

                                           cur_out_1 out sys_refcursor,

                                           cur_out_2 out sys_refcursor) is

--查询指定记录条数的数据，并返回总共记录数，返回多个数据集

begin

SELECT COUNT(*) into out_count FROM userinfo;

open cur_out_1 for

    SELECT * FROM userinfo where id < in_top;

open cur_out_2 for

    SELECT * FROM userinfo where id < 5;

end P_Sel_TopCount2;

 

Java调用

简单地写一个Java Class.

public void openCursor(){

    Connection conn = null;
    ResultSet rs = null;
    CallableStatement stmt = null;

    String sql = “{? = call PKG_HOTLINE.getHotline()}“;

    try{
       conn = getConnection();
       stmt = conn.prepareCall(sql);
       stmt.registerOutParameter(1,OracleTypes.CURSOR);
       stmt.registerOutParameter(2,OracleTypes.CURSOR);
       stmt.execute();
       rs = ((OracleCallableStatement)stmt).getCursor(1);

       while(rs.next()){

           String country = rs.getString(1);
           String pno = rs.getString(2);
           System.out.println(“country:“+country+“|pno:”+pno);

       }  

      rs = ((OracleCallableStatement)stmt).getCursor(2);
       while(rs.next()){
           String country = rs.getString(1);
           String pno = rs.getString(2);
           System.out.println(“country:“+country+“|pno:”+pno);
       }
    }

    catch(Exception ex)
    {
        ex.printStackTrace();
    }

    finally
    {
        closeConnection(conn,rs,stmt);
    }

}
