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);

    }

}
