title: Why BigQuery doesn't have an option to remove column?
body: <p>I'm looking for an option to remove a column from my BigQuery table like <code>ALTER TABLE TABLE_NAME DROP COLUMN_NAME</code> - but all I found in online was, drop the old table and create a new one. </p>
  
  <p>I'm just wondering, Is there any logical reason not having this option in BigQuery?</p>
