title: Update one column in mySQL table with CSV import
body: <p>Thought this would be easy but after searching S/O I'm not finding a solution. Can you help? Any direction will be appreciated.</p>
  <p>I have an existing 10-column table with column1 being <code>ID</code> (Primary) and column10 being <code>DATE</code>. I have a CSV file with 2 columns: ID (with IDs matching the table IDs) and DATE. I would like to import this CSV file to UPDATE (overwrite) the current info in the DATE column (currently 0000-00-00).</p>
  <p>Any thoughts? Thank you!</p>
