The following works for me with Databricks on all kinds of SQLs

  import sqlalchemy as SA
  import psycopg2
  host = 'your_host_url'
  username = 'your_user'
  password = 'your_passw'
  port = 5439
  url = "{d}+{driver}://{u}:{p}@{h}:{port}/{db}".\
            format(d="redshift",
            driver='psycopg2',
            u=username,
            p=password,
            h=host,
            port=port,
            db=db)
  engine = SA.create_engine(url)
  cnn = engine.connect()

  strSQL = "your_SQL ..."
  try:
      cnn.execute(strSQL)
  except:
      raise
