title: Progress bar for pandas.DataFrame.to_sql
body: <p>I want to migrate data from a large csv file to sqlite3 database.</p>
  
  <p>My code on Python 3.5 using pandas:</p>
  
  <pre><code>con = sqlite3.connect(DB_FILENAME)
  df = pd.read_csv(MLS_FULLPATH)
  df.to_sql(con=con, name="MLS", if_exists="replace", index=False)
  </code></pre>
  
  <p>Is it possible to print current status (progress bar) of execution of to_sql method? </p>
  
  <p>I looked the article about <a href="https://github.com/tqdm/tqdm" rel="noreferrer">tqdm</a>, but didn't find how to do this.</p>
