title: Global Temporary Tables - locking rows + Concurrency question
body: <p>I have a list of 100 entries that I want to process with multiple threads. Each thread will take up to 20 entries to process.</p>
  
  <p>I'm currently using global temp tables to store the entries that meet certain criteria -- I also do not want threads to overlap entries to process.</p>
  
  <p>How do I do this (preventing the overlap)?</p>
  
  <p>Thanks!</p>
