title: Check if QTemp table exists in Db2
body: <p>Is there a Db2 function that allows me to check if a table already exists?</p>
  
  <p>I have a stored procedure that executes a command to create a table, however I only want to call it if the table doesn't exist.</p>
  
  <p>I can't query the catalogs because files in Qtemp don't show in there.</p>
  
  <p>Thanks,</p>
