I'm sorry, but `select into outfile` is not possible on free hosting. The databases are on separate servers, and you can't access files on those servers anyways.
To dump the contents of a table to a CSV file, you can either use phpMyAdmin's Export feature to export the table to CSV, or you can write a custom PHP script which reads all the rows from the table and writes it to a file itself (using `file_put_contents`, `fwrite` or similar functions).
