An Access Table HAS NO ORDER - and a Query has no controlled order
either, unless you include an Order By clause. If you truly want a
random order (which, in this case, will be independent of the order of
arguments in the IN clause) use
SELECT id FROM mytable WHERE id IN(12, 14, 20, 21)
ORDER BY Rnd([ID]);
Hi John,
Your query works fast and accurate when I use it in MS Access (changed
it a little to my own needs).
The weird thing is, when I use the same query to fill a DataGrid (C#
WinForm) I get the same result every time.
For example: "SELECT TOP 8 id, latijn, nederlands FROM lexicon WHERE
datum>=1/1/2004 ORDER BY Rnd([id]);" returns a different result in
Access almost each time it is run. Filling a DataGrid on a Windows
Form results in the same order every time, although using the same
query.
I don't understand :o

vertaalKolom.DefaultValue = "";
dt.Columns.Add(vertaalKolom);
// do not allow new rows or deleting rows
DataView dv = new DataView(dt);
dv.AllowDelete = false;
dv.AllowNew = false;
// fill datagrid
dg.DataSource = dv;
