devart-bigquery-connector 1.1.0

New level of functionality and performance in data access via Python

Python Connector for Google BigQuery

Python Connector for Google BigQuery is a connectivity solution for accessing the Google BigQuery data warehouse from Python applications. It fully implements the Python DB API 2.0 specification. The connector is distributed as a wheel package for Windows and Windows Server.

GoogleSQL for BigQuery

The connector fully supports the BigQuery SQL dialects, data types, and query syntax, including functions, operators, and conditional expressions. Examples of supported BigQuery functions:

• Aggregate functions
• Array functions
• Datetime functions
• Navigation functions

Using the connector

To retrieve data from a database:

Import the module.

import devart.bigquery

Connect to a database using the connect() module method and obtain a connection object: If you have a refresh token, pass it in the connection string.

my_connection = devart.bigquery.connect(
    ProjectId="your_project_id;",
    DataSetId="your_dataset_id",
    RefreshToken="your_refresh_token"
)

If you don't have a refresh token, obtain it in the following way.

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

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

my_cursor = my_connection.cursor()

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

my_cursor.execute("SELECT * FROM employees")

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

for row in my_cursor.fetchall(): 
    print(row)
