Retrieving the last insert ID with Access

[simon.proctor]

Based on the help I had with a question last week, heres how to get the last insert ID from an access database using the recordset. This is Windows only.

If you are ever unfortunate enough to have to use Access then this should help you no end (it has for me :P)

        use Win32::OLE;
        use constant adOpenKeySet => 1;
        use constant adLockPessimistic => 2;
        use constant adCmdTable => '&H0002';

        my $db_connection = new Win32::OLE('ADODB.Connection');
    
        # Set the database connection details
        my $db_datasource = 'Driver={Microsoft Access Driver (*.mdb)};
+';
          $db_datasource .= 'DBQ=classifieds.mdb';
    
        # Connect to the database and tie the recordset object to the 
+database.
        $db_connection->Open($db_datasource);

        my $rs = new Win32::OLE("ADODB.Recordset");

        # you're going to have to define your consts that
        # you're using in the vbscript example
        $rs->Open('ADS', $db_connection, adOpenKeySet, adLockPessimist
+ic, adCmdTable);
        $rs->AddNew();
        $rs->{'title'}{'Value'} = 'Ad title';
        $rs->{'posted_by'}{'Value'} = 'Simon Proctor';
        $rs->{'date_authorised'}{'Value'} = 0;
        $rs->Update();
        my $last_id = $rs->{'ID'}{'Value'};
        $rs->close();
        $db_connection->close();

Thanks that's actually a problem I've encountered a few times. <idle_wish>It's common enough (and different enough in each DBMS) that a DBI function for this would be nice.</idle_wish> Oh and a link to the original discussion would be handy too.
