ADODB.Command Help

[hensa22]

I have a function return cursor, I use ADODB.command to call function.

my problem is : What data type is? in parameters that return cursor

Private Sub Command1_Click()
Dim rst As New ADODB.Recordset
Dim cmd As New ADODB.Command

Set cmd = New ADODB.Command
With cmd
       .ActiveConnection = Str_cnn
       .CommandText = "returncursor"
       .CommandType = adCmdStoredProc
       .Parameters.Append .CreateParameter("v", 'Here What data type is?', adParamReturnValue) 
       .Parameters.Append .CreateParameter("val1", adVarChar, adParamInput, 225, "select * from table")
       .Execute
        Set rst = .Parameters("v").Value
End With
        Set cmd = Nothing
End Sub

It work on SQL server or postgresql
