title: Leading Comma or Trailing Comma?
body: <p>I'm writting a SQL Coding Standard for the company where I work.</p>
  
  <p>I've read literature that says that <a href="http://www.thatjeffsmith.com/archive/2010/12/trailing-or-leading-commas/" rel="noreferrer">leading is the best option</a></p>
  
  <pre><code>select a.name
        ,a.surname
        ,a.address
  from person a 
  </code></pre>
  
  <p>But also trailing:</p>
  
  <pre><code>select a.name,
         a.surname,
         a.address
  from person a 
  </code></pre>
  
  <p>or <a href="http://blog.sqlauthority.com/2014/01/09/sql-server-auditors-passwords-and-exceptions-notes-from-the-field-010/" rel="noreferrer">non standard at all</a></p>
  
  <pre><code>select name, is_disabled,
  is_policy_checked, is_expiration_checked
  from sys.sql_logins;
  </code></pre>
  
  <p>My first question, is there any SQL Coding Standard worldwide accepted. If not, why not? I think this would be incredible usefull. Something like PEP8.</p>
  
  <p>And which would be the most practical way to solve this problem?</p>
  
  <p>Thanks in advance</p>
