=head1 DESCRIPTION

This utility is handy if you have a partially filled table (in CSV format, which
you can convert from spreadsheet or Google Sheet or whatever), where you have
some unique key already specified in the table (e.g. customer_id) and you want
to fill up other columns (e.g. customer_name, customer_email, last_order_date) from a
query:

 % mysql-fill-csv-columns-from-query DBNAME TABLE.csv 'SELECT c.NAME customer_name, c.email customer_email, (SELECT date FROM tblorders WHERE client_id=$customer_id ORDER BY date DESC LIMIT 1) last_order_time FROM tblclients WHERE id=$customer_id'
