asp调用oracle包里函数--------是一个返回记录集的问题,急！！！penitent兄你一定要帮我解决啊，同tinger (影虎)问题好相以,也是好多人得

beckhambobo 2002-11-27 05:08:48

CREATE TABLE student
(
id NUMBER,
name VARCHAR2(30),
sex VARCHAR2(10),
address VARCHAR2(100),
postcode VARCHAR2(10),
birthday DATE,
photo LONG RAW
)
/

2、建立带ref cursor定义的包和包体及函数：
CREATE OR REPLACE
package pkg_test as
/* 定义ref cursor类型
不加return类型，为弱类型，允许动态sql查询，
否则为强类型，无法使用动态sql查询;
*/
type myrctype is ref cursor;

--函数申明
function get(intID number) return myrctype;
end pkg_test;
/

CREATE OR REPLACE
package body pkg_test as
--函数体
function get(intID number) return myrctype is
rc myrctype; --定义ref cursor变量
sqlstr varchar2(500);
begin
if intID=0 then
--静态测试，直接用select语句直接返回结果
open rc for select id,name,sex,address,postcode,birthday
from student;
else
--动态sql赋值，用:w_id来申明该变量从外部获得
sqlstr := 'select id,name,sex,address,postcode,birthday
from student where id=:w_id';
--动态测试，用sqlstr字符串返回结果，用using关键词传递参数
open rc for sqlstr using intid;
end if;

return rc;
end get;

end pkg_test;
/
测试成功，绝对无问题以下是ASP的调用程序

<%@LANGUAGE="VBSCRIPT"%>

<%
set cm1 = Server.CreateObject("ADODB.Command")
cm1.ActiveConnection = MM_conn_STRING
cm1.CommandType = 1
cm1.CommandTimeout = 0
cm1.Prepared = true

cm1.CommandText = "{call pkg_test.get(?)}"
set para = cm1.Parameters
para.Append cm1.CreateParameter("intID",4,1,,0)
set rs = Server.CreateObject("ADODB.Recordset")
rs.CursorType = 0
rs.CursorLocation = 2
rs.LockType = 3
set rs.Source = cm1
rs.Open()
//set rs=cm1.Execute
cm1.ActiveConnection.Close
set cm1=nothing
%>

<% rs.close() %>

出错在rs.Open()位置，请问调用是否有问题
急！！！
