title: Is there a way to "truncate a row"?
body: <p>I would like to be able to clear all data in a row so that I still have the row with the primary key, but all other fields become their default value. Is there a simple command to do this in SQL or do I have to query the schema and loop through the columns manually?</p>
  <p>I happen to be using sqlite3 and knex.</p>
