title: '*' With Columns in SQL SELECT
body: <p>I am wondering if the SQL standard says anything about including table columns along with <code>*</code> in <code>select</code>. For example:</p>
  <pre><code>select *, id from users limit 10;
  </code></pre>
  <p>Will the above query return two columns both name id or will they be deduped? I tried with PostgreSQL and MySQL and both return both of the columns. Is this a part of the standard?</p>
