【解决方案一】：
On Error GoTo 11
Dim hisCNN As ADODB.Connection
Dim hisRST As ADODB.Recordset
Dim sSQL As String
Dim iZDS As Integer
Dim sBT As String
Dim sTEMP As String
Dim hisCMD As New mand
Dim Para1 As New ADODB.Parameter
Dim Para2 As New ADODB.Parameter
Dim Para3 As New ADODB.Parameter
Set hisCNN = New ADODB.Connection
hisCNN.CursorLocation = adUseClient
hisCNN.Open ＂Provider=MSDASQL.1;Persist Security Info=False;User ID=i_pathology;pwd=i_pathology;Data Source=aaa＂
MsgBox "连接数据库成功！"
//aaa是ＯＤＢＣ名
Set hisCMD.ActiveConnection = hisCNN
mandType = adCmdStoredProc
mandText = "zhi.F_get_sick_info"
Set Para1 = hisCMD.CreateParameter("as_patient_id", adVarChar, adParamInput, 100, "00")
Para1.Value = "3333333"
hisCMD.Parameters.Append Para1
Set Para2 = hisCMD.CreateParameter("as_io_flag", adVarChar, adParamInput, 100, "1")
Para2.Value = "1"
hisCMD.Parameters.Append Para2
MsgBox "hiscmd"
Set hisRST = hisCMD.Execute
MsgBox "得到记录集！"
如果把连接改成
Provider=msdaora.1;Data Source=服务名;User ID=i_pathology;Password=i_pathology;
的话，提示参数数量和类型不对．第三个参数是游标，我查了，应该不用赋值的．

PL/SQL 代码:
CREATE OR REPLACE PACKAGE "SCOTT"."PKG_TEST" AS
TYPE myrcType IS REF CURSOR;
FUNCTION get(strbarcode VARCHAR) RETURN myrcType;
END pkg_test;
CREATE OR REPLACE PACKAGE BODY "SCOTT"."PKG_TEST" AS
FUNCTION get(strbarcode IN VARCHAR) RETURN myrcType IS
rc myrcType;
BEGIN
OPEN rc FOR strbarcode;
RETURN rc;
END get;
END pkg_test;
