Check IB_Cursor1.RequestLive is True
and don't forget about Transactions.
I have this working fine:
IB_Transaction1.StartTransaction;
try
// it's necessarily for opening cursor and going to the first record
IB_Cursor1.First;
while not IB_Cursor1.Eof do
begin
IB_Cursor1.Edit;
IB_Cursor1.FieldByName('ABC').AsString:='123';
// IB_Cursor1.Fields[1].AsString:='123'; is a little faster
IB_Cursor1.Post;
IB_Cursor1.Next;
end;
IB_Transaction1.Commit;
except
IB_Transaction1.RollBack;
end;
I have checked up.
