How can I open a CSV file in MS-Excel via a link on an ASP page?

I have an ASP page that allows a user to select a database table, view all
of the table's field names, select field names of interest, and generate an
CSV file from a constructed SELECT statement. Upon completion I'd like to
offer the user a hyperlink that would open the CSV file up in MS-Excel; that
is, I'd like the link to mimic the behavior of double-clicking on a VSV
filename in WIndows Explorer.

Thanks in advance.
