Hi,

I am not sure whether I am posting the question in the correct place. Moderator please ensure.

I want to write data to an existing Access MDB from Excel. It should support adding and updating data in different tables in the MDB. Is there any way to do it? Please help.

You can do all of this via DAO (data access objects) or ADO (Active-X Data Objects) connections. There are a number of excellent resources online that explain these two in detail. Look into them, and let us know if you have any other questions.

Some examples



Sub AddData()
Dim oConn As Object
Dim oRS As Object
Dim sSQL As String

Set oConn = CreateObject("ADODB.Connection")
oConn.Open = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & "c:\bob.mdb"

sSQL = "INSERT INTO Contacts (FirstName, LastName,Phone, Notes) " & _
" VALUES ('Bob','Phillips','01202 345678','me')"
oConn.Execute sSQL

oConn.Close
Set oConn = Nothing
End Sub

Sub GetData()
Const adOpenForwardOnly As Long = 0
Const adLockReadOnly As Long = 1
Const adCmdText As Long = 1
Dim oRS As Object
Dim sConnect As String
Dim sSQL As String
Dim ary

sConnect = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & "c:\bob.mdb"

sSQL = "SELECT * From Contacts"
Set oRS = CreateObject("ADODB.Recordset")
oRS.Open sSQL, sConnect, adOpenForwardOnly, _
adLockReadOnly, adCmdText

' Check to make sure we received data.
If Not oRS.EOF Then
ary = oRS.getrows
MsgBox ary(0, 0) & " " & ary(1, 0) & ", " & ary(2, 0)
Else
MsgBox "No records returned.", vbCritical
End If

oRS.Close
Set oRS = Nothing
End Sub

Sub UpdateData()
Const adOpenForwardOnly As Long = 0
Const adLockReadOnly As Long = 1
Const adCmdText As Long = 1
Dim oConn As Object
Dim oRS As Object
Dim sConnect As String
Dim sSQL As String
Dim ary

sConnect = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & "c:\bob.mdb"

sSQL = "SELECT * From Contacts"
Set oRS = CreateObject("ADODB.Recordset")
oRS.Open sSQL, sConnect, adOpenForwardOnly, _
adLockReadOnly, adCmdText

' Check to make sure we received data.
If oRS.EOF Then
MsgBox "No records returned.", vbCritical
Else
sSQL = "UPDATE Contacts " & _
" SET Phone = 'None' " & _
"WHERE FirstName = 'Bob' AND LastName = 'Phillips'"
oRS.ActiveConnection.Execute sSQL

sSQL = "SELECT * From Contacts"
oRS.ActiveConnection.Execute sSQL
ary = oRS.getrows
MsgBox ary(0, 0) & " " & ary(1, 0) & ", " & ary(2, 0)
End If


oRS.Close
Set oRS = Nothing
End Sub
