>Don't do databases with LINQ. LINQ to SQL is essentially dead. The syntax will also be different in C# than VB. Which are you looking for?

Somebody here told me to use Linq rather the traditonial scanning through the traditional ado.net recordset to aggregate information from a database extraction.

Now I'm puzzled. And I'm working in vb.net btw.

This seems to work for me btw (osql.execute extracts an access query in a datatable osql.dt).

        Dim osql As New sqlClass : osql.Execute("qryBestelKK")
        Dim orders As IEnumerable(Of DataRow) = osql.dt.AsEnumerable

        Dim test = From r In orders _
                   Group r By name = r.Field(Of String)("KL_Naam") _
                   Into g = Group Select New With {.Name = name, .total = g.Sum(Function(r) r.Field(Of Decimal)("Bestd_Waarde"))}

        For Each r In test
            Console.WriteLine("name: {0} total {1}", r.Name, r.total)
        Next

Can't begin to imagine why you would say Linq is dead. It is sooooo straightforward :)

BTW this is just one of the manipulation I do on that table, but the others are scalars, and they were easier to figure out.

Thanks for caring.
