Hello,

i'd like to export Excel data into an existing Access database. But when a
field is empty in Excel, i get an error. I tried to put NOT NULL fields in
the database but that doesn't change.
Do you have any ideas?

Sub ADOFromExcelToAccess()
' exports data from the active worksheet to a table in an Access database
' this procedure must be edited before use
Dim cn As ADODB.Connection, rs As ADODB.Recordset, r As Long
Dim DBPath As String

DBPath = "J:\bdd.mdb"

' connect to the Access database
Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; " & _
"Data Source=" & DBPath & ";"
' open a recordset
Set rs = New ADODB.Recordset
rs.Open "INSTRUMENT", cn, adOpenKeyset, adLockOptimistic, adCmdTable
' all records in a table
r = 5 ' the start row in the worksheet
Do While Len(Range("B" & r).Formula) 0
' repeat until first empty cell in column A
With rs
.AddNew ' create a new record
' add values to each field in the record
.Fields("Instrument_id") = Range("B" & r).Value
.Fields("Name") = Range("C" & r).Value
.Fields("ShortName") = Range("D" & r).Value
.Fields("MasterInstrument_id") = Range("E" & r).Value
.Fields("Instrument_Type") = Range("F" & r).Value
.Fields("Share_Classe") = Range("G" & r).Value
.Fields("Series") = Range("H" & r).Value
.Fields("Currency_id") = Range("I" & r).Value
.Fields("Flag") = Range("J" & r).Value
.Fields("Management_fee") = Range("K" & r).Value
.Fields("Administration_fee") = Range("L" & r).Value
.Fields("Otherfee_x") = Range("M" & r).Value
.Fields("Performance_fee") = Range("N" & r).Value
.Fields("Hurdle_Rate") = Range("O" & r).Value
.Fields("High_Watermark") = Range("P" & r).Value
.Update ' stores the new record
End With
r = r + 1 ' next row
Loop
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub


Thanks !

The trick is if the cell is empty then you don't want to send anything...
Here is how I would modify your first field. The same applies for the rest of
the fields...

if Range("B" & r).Value < empty then .Fields("Instrument_id") = Range("B" &
r).Value

The function Update used with the recordset insert rows into the database,
and i would like to update it. What can i do?

Presumably something very similar, except instead of the .AddNew line:
..Filter = "Instrument_id = " & Range("B" & r).Value
