title: Delete bigquery table content with pandas-gbq
body: <p>I'm deleting big query rows from a table, using the "pandas-gbq" library, which works fine.</p>
  
  <p>However, since this is a "read" action, by default the whole table content is being fetched, and, I do not want it to occur, since that is unnecessary.</p>
  
  <p>This is my current code below, any ideas about a way to perform a delete action without fetching the table as a df?</p>
  
  <p>Thanks in advance.</p>
  
  <h1>Delete gbq table rows - Today and yesterday</h1>
  
  <pre><code>sql = """
  DELETE FROM `bla.bla.bla`
  WHERE Day = '{today}' OR Day = '{yesterday}'
  """
  sql = sql.format(today = curr_date, yesterday= prev_date)
  pandas_gbq.read_gbq(sql, project_id=project_id, credentials=credentials)
  </code></pre>
