Overwrite event - data from SQL Server to MySQL In MySQL is it possible to execute an update query with values selected from external SQL Server database?

I'd like to execute every night a timed query, which overwrites some data in MySQL with data on SQL Server.
Write PHP/Perl/Java/VB/whatever code to SELECT from one db server and INSERT/UPDATE/whatever into the other.

For "timed", use cron (if on *nix).
