To retrieve data from Google BigQuery:

2. Connect to a database using the connect() module method and obtain a connection object.

   response = bigquery.signin()
   my_connection = bigquery.connect(
       ProjectId="your_project_id",
       DataSetId="your_dataset_id",
       RefreshToken=response["Refresh Token"]
   )

3. Create a cursor object using the cursor() connection method.

   my_cursor = my_connection.cursor()

4. Execute the SQL statement using the execute() cursor method.

   my_cursor.execute("SELECT * FROM employees")

5. Retrieve the result set using one of the fetch*() cursor methods.
