body: <p>Among other questions, <a href="https://stackoverflow.com/questions/1590799/delete-all-rows-in-a-table-based-on-another-table">this one asked how to delete from a join</a>.</p>
  
  <p>My question: How much of this is standard SQL? On which databases would this actually work (most notably for me would be Oracle, MySQL and SQLServer)?</p>
