  • Basis is to use python client library for BigQuery google-cloud-bigquery. You install it with: [code]pip install --upgrade google-cloud-bigquery [/code]Depending on where you want to execute your Python code you need to authenticate, there are sev.
  • BigQuery Google App Engine (GAE) Java Example Project goal. This is an Eclipse GAE Java project for a servlet accessing BigQuery using a Service Account for authentication.

This tutorial provides a step by step guide to using the encrypted BigQueryclient (ebq).

Simple Python client for interacting with Google BigQuery. This client provides an API for retrieving and inserting BigQuery data by wrapping Google's low-level API client library. BigQuery Data Transfer API: Transfers data from partner SaaS applications to Google BigQuery on a scheduled, managed basis. This page contains information about getting started with the BigQuery Data Transfer API using the Google API Client Library for Python. Metabase 0.31.0.0 - Easy data analysis. Download the latest versions of the best Mac apps at safe and trusted MacUpdate. Installing the Driver The Simba ODBC Driver for Google BigQuery is available for macOS as a.dmg file named Simba ODBCDriverforGoogle BigQuery.dmg. The driver supports both 32- and 64-bit client applications. Google BigQuery Client Library for Perl. Contribute to runarbu/Google-BigQuery development by creating an account on GitHub.

ebq enables storing of private data in encrypted form on BigQuerywhile supporting a meaningful subset of the client query types that arecurrently supported by these tools, maintaining scalable performance, andkeeping the client data and the content of the queries as hidden as possiblefrom the server.

The command line tool 'bq' is extended and named 'ebq' (i.e. encrypted bq)which encrypts data before loading and transforms query to work overencrypted data.

Preliminary Requirements

  • Since ebq is a replacement for the bq command line tool, it alsoneeds similar access to a BigQuery service and project setup.Please set up a project before proceeding further.
    • When bq or ebq is run the first time, you will be prompted for a defaultproject ID which will be stored in your .bigqueryrc file (see here for bquser guide).
  • Depending on where you install ebq you may wish to set an alias to it foreasier access, e.g. alias ebq='$HOME/.local/bin/ebq'

Dataset Management

Create a test dataset

Makes a dataset named testdataset in the default project.

List datasets

Returns a list of datasets in the default project.

Loading (importing) a file of data

Figure 1: 'cars.schema', an example extended schema

Figure 2: 'cars.csv', an example of csv data

In the local directory, copy data in figure 1 and figure 2 to filescars.schema and cars.csv, respectively. cars.schema is an example ofextended schema which along with standard bq fields also includes an'encrypt' field. cars.csv contains example data that may be partiallyencrypted and uploaded to BigQuery.

This will upload the data in cars.csv to BigQuery and create a table carsin testdataset dataset by first encrypting parts of the data in cars.csvfile as specified by the extended schema file cars.schema. It will use thekey in key_file to encrypt the data, however, if the key does not existthen it will create a key and store it in the same key_file path that isspecified. Loading can take over a minute sometimes.

Show the schema

This returns the schema of the cars table indicating field name and theirtype. Note that for encrypted fields the type returned is ciphertext.

List the top n rows of the table

Mac

This acts like head(1) and returns the top rows of the data directly fromBigQuery without handling decryption. We can see that certain fieldshave values that are clear (e.g. Year) while other fields have encrypted,base64 encoded values. Email client for mac.

Example Queries

Basic query

This query returns selected fields from the cars table. The local key_fileis used by ebq to decrypt columns on the client before printing.

Query with WHERE condition

This query returns only the rows where the year values are greater than 1997.

Query with private WHERE condition using CONTAINS

This query returns the single row where the Description field contains themoon roof sequence of words. Note the case insensitivty of the CONTAINSquery: CONTAINS 'Moon Roof' would also return the same result.

Query with private WHERE condition using (equality)

This query returns the two rows where the Make field equals Chevy. TheMake field is a pseudonymn and thus is case sensitive.

Query with expression on (encrypted) fields

Even though Price is stored encrypted on BigQuery, ebq first decrypts theresponse and then evaluates the expression before displaying the result.

Query with aggregation of (privately) selected records

This query returns the sum of all the values in the Invoice_Price field,which is 14050.0 for our test data. The sum is calculated securely on theserver side using the special type of encryption, homomorphic, and the newsummation value is returned while still encrypted. The client decrypts itwith key_file.

Query with aggregation of (privately) selected records using expressions

Bigquery Client For Machine Learning

This query returns the sum and average of Invoice_Price (an int value) andHoldback_Percentage (a float value) appropriately modified based on theexpression, with return values of 7290.0 and 0.63, respectively. Note thatebq can accept simple linear expressions with the aggregation functionsAVG and SUM.

Delete table and dataset

Ftp Client For Mac

This command removes the cars table.

Vmware Horizon Client For Mac

This command removes the entire dataset named testdataset from thedefault project.
