title: Delete row if table exists SQL
body: <p>I have a script that drops a load of tables using DROP TABLE IF EXISTS, this works.</p>
  
  <p>There is also a delete in this script to DELETE a row from another table that I do not manage. This table may or may not exist.Is there any to check the table exists before attempting to delete a row?</p>
  
  <p>this needs to work for MYSQL and SQLServer</p>
  
  <p>thanks
  Alex</p>
