The code below returns -3 for the absoluteposition, 'one' just before the update of the first field and fails with runtime error 3021

If the recordset is not eof, I cannot understand the error
Dim oConn As ADODB.Connection
   Dim rs As ADODB.Recordset
   Set oConn = New ADODB.Connection
   Set rs = New ADODB.Recordset
    oConn.Open "driver={MySQL ODBC 5.1 Driver}; server=localhost; uid=xxxxx; pwd=xxxx; database=intranet; option=3"
 
tName = "products"
 
'Set rs = oConn.OpenRecordset(tName, dbOpenTable)
rs.CursorType = adOpenKeyset
rs.CursorLocation = adUseClient
rs.LockType = adLockOptimistic
 
rs.Open tName, oConn, adOpenKeyset, adLockOptimistic
 
'rs.Execute ("Delete Products.* from Products")
' get all records in a table
r2 = 2 ' the start row in the worksheet
Do While Cells(r2, 1) <> ""
   rs.MoveFirst
 
   rs.Find "PItemRef=" & Chr(34) & Cells(r2, 4).Value & Chr(34)
   MsgBox (rs.AbsolutePosition)
 
   If (rs.EOF) And (rs.BOF) Then
 
      rs.AddNew
      rs.Fields("PItemID") = Cells(r2, 1).Value
      rs.Fields("PProductID") = Cells(r2, 2).Value
      rs.Fields("PProductName") = Cells(r2, 3).Value
      rs.Fields("PItemRef") = Cells(r2, 4).Value

      rs.Fields("PCategoryName") = Cells(r2, 6).Value

              ID = DLookup("CatID", "Categories", "Category = " & Chr(34) & cats(x) & Chr(34) & " and ParentID=" & ID)
          Next

Hi pzh20
The line
If (rs.EOF) And (rs.BOF) Then
tests if the recordset is empty (otherwise both EOF and BOF cannot be true)
maybe you meant to use
If (rs.EOF) Or (rs.BOF) Then
since you get rs.EOF when the item was not found with rs.Find
absoluteposition for EOF is -3

Regards,
Stellan

Hi again,
Maybe I was not clear enough.
The expression
rs.EOF And rs.BOF
is True only if rs is empty (no records)
and what you want to test is if no record was found
using rs.Find
If no record was found, only rs.EOF is True

So, please try to change to

If rs.EOF Then
 rs.AddNew
 ...


Kind regards,
Stellan
