>>>Hi all,

>>Yes, you can index remote view, i.e. cursor behind it. In regard to using, it depends on existing application design. I found that in most cases it's more natural to call server stored procedures (through SQLExec), and get data from the server to local cursor by the same way, i.e. you may 'run' the same Select statements that you use now.

It will have to do for the quick and dirty. The main point of going to C/S is that you have to change your mindset, from working with tables to working with recordsets. Since now everything is pulled down the wire, it's a trick to pull down only what you need. If it's a lookup table, pull down the keys and searchable fields, then pull the complete selected record. If it's a transactional table, pull complete records for the current document only. If it's for reporting, don't touch anything until you have the time :).

You may need to create two views for some tables - the long/narrow and short/wide. You may also use views for most of the stuff in the input forms - and use SPT for the tricky parts. Depending on the size of the app, it may take some time to optimize it all.

Going just with views, you can do it quick. If you have the time to do parametrized views for most important cases, go for it. Do the rest when you can.
