Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

  • Python >= 3.1

Installing

pip install superQuery

Authentication

  • Go to superquery.io and log in/sign up
  • In the left side-bar, click on the "Integrations" icon
  • Scroll down until you see "Python" and click "Connect"
  • Note the username and password
  • Set these two environment variables in your local environment:
export SUPERQUERY_USERNAME=xxxxxx
export SUPERQUERY_PASSWORD=xxxxxx

The basic flow

  • Get your autentication details (See "Authentication" above)
  • Import the superQuery library:
from superQuery import superQuery
  • Create a superQuery client:
client = superQuery.Client()
  • Set your Google Cloud billing project:
client.project("yourBillingProjectId")
  • Decide what SQL statement you'd like to run:
QUERY = """SELECT name FROM `bigquery-public-data.usa_names.usa_1910_current` LIMIT 10"""
  • Get your results generator:
result = client.query(QUERY)
  • Get your results by iteration (Option A)
for row in result:
    print(row.name)
  • Get your results by iteration and store to a Pandas dataframe (Option B)
df = result.to_df()

Running queries with minimum code using Jupyter notebook

  • Get your autentication details (See "Authentication" above)
  • Import the superQuery library:
from superQuery import superQuery
  • Load the %%superquery magic
%load_ext superQuery
  • Run your SQL query and display the resulting Pandas dataframe (Option A)
%%superquery --project yourBillingProjectId
SELECT name FROM `bigquery-public-data.usa_names.usa_1910_current` LIMIT 10
  • Run your SQL query and save the resulting Pandas dataframe to a new variable df, which is given as an argument to the %%superquery cell magic (Option B)
%%superquery --project yourBillingProjectId --dest df
SELECT name FROM `bigquery-public-data.usa_names.usa_1910_current` LIMIT 10
  • Run your SQL query and save the resulting Pandas dataframe to a new variable df and query execution statistics to df_stats. Also provide query input parameters with $params (Option C)
params = superQuery.Configuration().configure_parameters({
    'fromYear': '2000', 
    'toYear': '2019'
})
%%superquery --project yourBillingProjectId --params $params --dest df --stats df_stats
SELECT name FROM `bigquery-public-data.usa_names.usa_1910_current` WHERE year >= CAST(@fromYear AS INT64) LIMIT 10

Examples

Running examples/start.ipynb in Google Colab

  • Open In Colab
  • Update the credentials in the notebook by following the steps above under "Authentication"
  • Run it!

Running examples/start.ipynb in Jupyter notebook

  • Launch Jupyter locally with jupyter notebook
  • Download examples/start.ipynb to your local machine and open it from Jupyter
  • Update the credentials in the notebook by following the steps above under "Authentication"
  • Run it

Running examples/start.py

  • First, set these two variables in your local environment:
export SUPERQUERY_USERNAME=xxxxxx
export SUPERQUERY_PASSWORD=xxxxxx
  • Enter your Google Cloud billing project into this line:
client.project("yourBillingProjectId")
  • Alternatively: If you prefer to use your username/password combination directly for each query, then inside start.py enter your details obtained from the superquery.io web interface where it shows xxxxxxx below
query_job = client.query(
    "SELECT field FROM `projectId.datasetId.tableID` WHERE _PARTITIONTIME = \"20xx-xx-xx\"", 
    username="xxxxxxxxx",
    password="xxxxxxxxx")
  • Now run
python3 examples/start_here.py

Running magic_example.ipynb in Jupyter notebook

  • Launch Jupyter locally with jupyter notebook
  • Download magic_example.ipynb to your local machine and open it from Jupyter
  • Update the credentials in the notebook by following the steps above under "Authentication"
  • Run it!
