Hi!

_Tally will not be set for remote views. Thus it is not recommended to use _Tally for views when you plan to move to SQl Server or other database in the future. You can use following:

if requery('MyView')=1 AND reccount('MyView')>0
...
endif

>2.) If I perform a requery() from inside an EXE I seem to (sometimes) run code that is unexpected based on the _tally value.
>3.) The Hacker's Guide doesn't list requery() as one of the items that affects _tally.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
