That the problem with SQL SELECT style DBF apps. Bloated temp directorys and bloated CDX's. Switch to SEEK. The planning is tighter, the CDXs are smaller and the app will scream like a C++ interface. Why CHUG along like a an overblown list server when there are features available that allow us to build apps that run like a swiss movement?

One could wager that a lot of the negative press VFP gets is from "browser" implementations of what should be a transaction engine. Use of SELECT should be limited. When over used: Selects are just another too-easy method to build a browser app. - a grid - an expensive glorified spreadsheet - something for future prospects to couch their doubts with.
