C#调用ORACLE存储过程返回结果集
Oracle中scott用户下创建存储过程:
(注:从9i开始有了sys_refcursor这种类型,在以前的Oracle版本中需要使用REF CURSOR,并且还需放在一个程序包中)
create or replace procedure sp_getdept
(result out sys_refcursor)
as
begin
open result for select * from dept;
end;

.net环境下(用的WINDOWS程序,WEB基本相同;环境为VS2005)
==记着先添加引用System.Data.OracleClient
