title: Deleting many rows from a table at once
body: <p>I have a table named as person (which contains the login id of users). I was testing my application and made several test users. So right now this table has many test users and some normal users. </p>
  
  <p>I want to know how can I delete all the test users? </p>
  
  <p>Deleting all users one by one using <code>DELETE login FROM person where login = 'test_user' ;</code> will take long time. </p>
  
  <p>PS: The test users' names do not contain test in it :/ They are just random names. </p>
