title: Simple way to automatically convert INSERT statements to UPDATEs?
body: <p>I want to use the output of mysqldump to update entries in a live database. I don't want to delete the entries first, simple update statements are fine. Is there a simple way to convert the output of mysqldump which contains INSERT statements to the corresponding UPDATE statements?</p>
  
  <p>It seems such a basic feature, so I'm sure someone created a tool or came up with a method to do it quickly, so people don't have to reinvent the wheel all the time by everyone writing their own scripts for this.</p>
  
  <p>Edit: I'm looking for a generic solution, not one where I have to enumerate the actual table columns by hand. It's a generic problem, so I think there should be a table independent solution for it.</p>
