How to update an Access Table using VBA

How to update an Access Table using ADO

The following code snippet would be helpful to update an Access 2007 database table using VBA. The code uses ADO and requires a reference to ActiveX Data Objects Library

The sample uses a simple table which contains a name and a location field.

The code uses the SQL update query to update the database. The query is executed by the ADO’s command execute method

Sub Simple_SQL_Update_Data()

Dim Cn As ADODB.Connection '* Connection String

Dim oCm As ADODB.Command '* Command Object

Dim sName As String

Dim sLocation As String

Dim iRecAffected As Integer

On Error GoTo ADO_ERROR

Set Cn = New ADODB.Connection

Cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\comp\Documents\SampleDB.accdb;Persist Security Info=False"

Cn.ConnectionTimeout = 40

Cn.Open

sName = "Krishna Vepakomma"

sLocation = "Cincinnati, OH"

Set oCm = New ADODB.Command

oCm.ActiveConnection = Cn

oCm.CommandText = "Update SampleTable Set Location ='" & sLocation & "' where UserName='" & sName & "'"

oCm.Execute iRecAffected

If iRecAffected = 0 Then

MsgBox "No records inserted"

End If

If Cn.State <> adStateClosed Then

Cn.Close

End If

Application.StatusBar = False

If Not oCm Is Nothing Then Set oCm = Nothing

If Not Cn Is Nothing Then Set Cn = Nothing

ADO_ERROR:

If Err <> 0 Then

Debug.Assert Err = 0

MsgBox Err.Description

Err.Clear

Resume Next

End If

End Sub
