project_id : str, optional

Google BigQuery Account project ID. Optional when available from the environment.

index_col : str, optional

Name of result column to use for index in results DataFrame.

col_order : list(str), optional

reauth : boolean, default False

Force Google BigQuery to re-authenticate the user. This is useful if multiple accounts are used.

auth_local_webserver : boolean, default False

Use the local webserver flow instead of the console flow when getting user credentials.

New in version 0.2.0 of pandas-gbq.

dialect : str, default ‘legacy’

Note: The default value is changing to ‘standard’ in a future verion.

SQL syntax dialect to use. Value can be one of:


Use BigQuery’s legacy SQL dialect. For more information see BigQuery Legacy SQL Reference.


Use BigQuery’s standard SQL, which is compliant with the SQL 2011 standard. For more information see BigQuery Standard SQL Reference.

Changed in version 0.24.0.

location : str, optional

Location where the query job should run. See the BigQuery locations documentation for a list of available locations. The location must match that of any datasets used in the query.

configuration : dict, optional

Query config parameters for job processing. For example:

configuration = {‘query’: {‘useQueryCache’: False}}

For more information see BigQuery REST API Reference.

New in version 0.8.0 of pandas-gbq.

New in version 0.24.0.

use_bqstorage_api : bool, default False

Use the BigQuery Storage API to download query results quickly, but at an increased cost. To use this API, first enable it in the Cloud Console. You must also have the bigquery.readsessions.create permission on the project you are billing queries to.

This feature requires version 0.10.0 or later of the pandas-gbq package. It also requires the google-cloud-bigquery-storage and fastavro packages.

New in version 0.25.0.

private_key : str, deprecated

Deprecated in pandas-gbq version 0.8.0. Use the credentials parameter and google.oauth2.service_account.Credentials.from_service_account_info() or google.oauth2.service_account.Credentials.from_service_account_file() instead.

Service account private key in JSON format. Can be file path or string contents. This is useful for remote server authentication (eg. Jupyter/IPython notebook on remote host).
