title: Rollback and Raiseerror, which first?
body: <p>I sometimes perform the following set of statement in the following order:</p>
  
  <pre><code>Raiseerror(...)
  Rollback;
  </code></pre>
  
  <p>but I am wondering if it cause the same effect as below:</p>
  
  <pre><code>Rollback;
  Raiseerror(...)
  </code></pre>
  
  <p>I understand they are the same and cause the same effect. Doing Rollback first, after execution it continues executing on the following line, that is, Raiseerrror(...)</p>
  
  <p>Could anyone confirm this? or is preferable to execute this set of statements in a concret way? </p>
