Hmmm. It's a list of customers and yearly turnover totals for current year, year minus one and so on. The turnover totals aren't stored so I am calculating them in the grid cursor SQL i.e. select accountcode, name, Thisform.GetBalance(accountcode, 1) as prev1 ... and so on. GetBalance() uses an optimised sum .. for expression. So it's the calculation of the balances for 10k records over a network that is taking 10 seconds which is on the slow side for this use case. Oh for built-in paging functionality :) _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
