Thread: Begin/Rollback/Commit Transaction for access

    Begin/Rollback/Commit Transaction for access


    Anyone knows if these exist in access, could you point at a piece of code for this?

    Info: These are SQL transactions which are a bunch of queries, they change your database however if any of the queries fails the whole database reverts back to original state.

    Does anyone know of a way for doing it?

    Transaction processing is handled in Access via ADO (ActiveX Data Objects) connections. Here's an example of an ADO transaction from the Access 2007 Programming By Example book:

    Sub CreateTransactionADO() 
        Dim conn As ADODB.Connection 
        On Error GoTo ErrorHandler 
        Set conn = New ADODB.Connection 
        With conn 
            .Provider = "Microsoft.Jet.OLEDB.4.0" 
            .ConnectionString = "Data Source=C:\Acc07_ByExample\Northwind.mdb" 
             'insert a new customer record
            .Execute "INSERT INTO Customers " & _ 
            "Values ('GWIPO','Gwiazda Polarna'," & _ 
            "'Marcin Garnia', 'Sales Manager', 'ul.Majewskiego 10'," & _ 
            "'Warsawa', Null, '02-106', 'Poland', '0114822230445', Null)" 
             'insert the order for that customer
            .Execute "INSERT INTO Orders" & _ 
            " (CustomerId, EmployeeId, OrderDate, RequiredDate)" & _ 
            " Values ('GWIPO', 1, Date(), Date()+5)" 
            MsgBox "Both inserts completed." 
        End With 
        Set conn = Nothing 
        Exit Sub 
        If Err.Number = -2147467259 Then 
            MsgBox Err.Description 
            Resume ExitHere 
            MsgBox Err.Description 
            With conn 
            End With 
            Resume ExitHere 
        End If 
    End Sub

    You can get more info from Access Help, as long as you have a reference set to the ADO Object Library.

    Also, to create a connection to your current open database (the database you're writing the code in) with ADO you would use: CurrentProject.Connection
