title: Truncate all tables (most of which have constraints).  How to temporarily drop them
body: <p>I have a development database (MYSQL) which I would like to load with fresh data at some point.  I would like to delete the content of all tables.
  What is the best way, as automated as possible, to delete the content of all tables (including those that have foreign key constraints). Is there a truncate all/ drop all equivalent constraints?</p>
  
  <p>Thanks</p>
