fyi NOFILTER==READWRITE --
rk -----Original Message----- From: ProfoxTech <profoxtech-boun...@leafe.com> On Behalf Of Frank Cazabon Sent: Monday, April 09, 2018 1:36 PM To: profoxt...@leafe.com Subject: Re: .tmp Is Read-Only Paul, this is probably due to VFP's optimisation. Always get in the habit of using NOFILTER as part of your SQL SELECT command. Try it and see if it works in both scenarios for you. Without the NOFILTER, VFP may optimise the query by just opening the cursor again with a filter applied, this may then cause problems while indexing. My guess is that it optimises it slightly differently in the development environment so it works in that case, but in the runtime it handles it by just filtering it. Frank.
