i'm sure this is simple to do, but i can't find the answer in the
search engines.
i have an access db with 400,000 records. i produce queries of 5,000
records at a time exported into an excel file. sometimes people will
update items in the excel file, send it back to me in the exact format
i sent it, and i just do an update to the saved query in the db with
the new info.
this time, the file i sent had 3,500 records, and instead of keeping
all the rows in the excel file, the person updated certain rows and
removed the rest - so now i have 500 records.
how do a take this excel file of 500 records and auto-match them up to
my 400,000 db records and update (copy over) with the new info from
excel?
thank you.
