Question : using autoexec macro to update database with windows  scheduled tasks

Hello,
I have created an autoexec macro and modules and using windows scheduled tasks to update database at different times- I have my queries working right-
but now I realize if I just open the database- or if someone did- during a time where a query is scheduled to update- the update will run-
meaning it could caused to run mulitple times
is this true?
Does that mean the only time this will work correctly is at times like midnight when no one is in database?

thank you
