Dim objRS As ADODB.Recordset

Set objCon = New ADODB.Connection
Set objCom = New ADODB.Command


'Open connection
objCon.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Extended Properties=dBASE IV;" & _
"Data Source=c:\MDW2;"

objCon.Open objCon.ConnectionString


'get record set
Set objRS = New ADODB.Recordset


'Run multi select statment
objRS.Open "SELECT * From Patients", objCon, adOpenStatic, adLockReadOnly, adCmdText


If objRS.RecordCount > 0 Then
objRS.MoveLast
End If

The above code works

However if I replace the recordset statement with * with a specific field name eg. surname

objRS.Open "SELECT surname From Patients", objCon, adOpenStatic, adLockReadOnly, adCmdText

This cause an error

No value given for one or more required paramters

Does anybody know how to get this working?

TIA

I've never used a provider statement for dbase or foxpro access... I've always set up a DSN on the server, and then used the dsn to connect. I've never had any problems this way.
