为了让这个工作起来,你需要做很多管道工作.试试这本指南.

它包括这个样本.它假设您已经引用了ADO,您已经下载了Oracle的OleDB提供程序,并且您已经设置了TNSNames.ora文件.如果您不想使用TNSNames.ora,可以尝试替代连接字符串

Dim Oracon As ADODB.Connection
Dim recset As New ADODB.Recordset
Dim cmd As New ADODB.Command
Dim param1 As New ADODB.Parameter
Dim param2 As New ADODB.Parameter
Dim objErr As ADODB.Error

Dim Message, Title, Default, DeptValue
Message = "Enter a department number (10, 20, or 30)"
Title = "Choose a Department"
Default = "30"

On Error GoTo err_test
DeptValue = InputBox(Message, Title, Default)
If DeptValue = "" Then Exit Sub
If DeptValue < 10 Or DeptValue > 30 Then DeptValue = 30

Set Oracon = CreateObject("ADODB.Connection")
Oracon.ConnectionString = "Provider=OraOLEDB.Oracle;" & _
                          "Data Source=exampledb;" & _
                          "User ID=scott;" & _
                          "Password=tiger;"  
Oracon.Open
Set cmd = New ADODB.Command
Set cmd.ActiveConnection = Oracon
Set param1 = cmd.CreateParameter("param1", adSmallInt, adParamInput, ,
                                DeptValue)
cmd.Parameters.Append param1
Set param2 = cmd.CreateParameter("param2", adSmallInt, adParamOutput)
cmd.Parameters.Append param2

' Enable PLSQLRSet property
Cmd.Properties ("PLSQLRSet") = TRUE  

cmd.CommandText = "{CALL Employees.GetEmpRecords(?, ?)}"
Set recset = cmd.Execute

' Disable PLSQLRSet property
Cmd.Properties ("PLSQLRSet") = FALSE 

Do While Not recset.EOF
   MsgBox "Number: " & recset.Fields("empno").Value & "  Name: " &
   recset.Fields("ename").Value & "  Dept: " & recset.Fields("deptno").Value
   recset.MoveNext
Loop

Exit Sub

err_test:
    MsgBox Error$
    For Each objErr In Oracon.Errors
        MsgBox objErr.Description
    Next
    Oracon.Errors.Clear
    Resume Next
