title: Catch script that changes the data
body: <p>we've got an annoying effect on one of our productive costumer environments. on a regular basis (2-3 times a week, but not always at the same time) a script, and i have no idea where that script comes from (maybe from a programm, maybe a script somewhere on the db-server), changes like 1,5 Millions Rows and updates 3 columns in one table. </p>
  
  <p>Is there any possible way to catch and find out what script is responsible for the changes?</p>
  
  <p>Thanks for four help and your ideas.</p>
