Mike I cant answer the question you have, but I can answer my practice:
>From the SATTCHED table I always project a temp Table, that I use in forms and reports, there I never experience a performance Issue, when I need to push back some updates to the foreign DB , I do in an eep (mostly in a form (requires 7.6)). Having said that I might add using clause is for identifying the primary Key, so I guess that the best is have a using clause for field()s) that uniquely identifies a row in the foreign DB-table. After that you can use the alias to name each field. This is only TTBOMK and I am still learning.
