Query Google BigQuery	BigQuery	Use [`sql.from()`](/flux/v0/stdlib/sql/from/) with the `bigquery` driver to query Google BigQuery.	flux_v0 name parent BigQuery SQL databases	101	/flux/v0/stdlib/sql/from/	```js import "sql" sql.from( driverName: "bigquery", dataSourceName: "bigquery://projectid/?apiKey=mySuP3r5ecR3tAP1K3y", query: "SELECT * FROM exampleTable", ) ```

To query Google BigQuery with Flux:

1. Import the sql package.

2. Use sql.from() and provide the following parameters:

   • driverName: bigquery
   • dataSourceName: See data source name
   • query: SQL query to execute

import "sql"

sql.from(
    driverName: "bigquery",
    dataSourceName: "bigquery://projectid/?apiKey=mySuP3r5ecR3tAP1K3y",
    query: "SELECT * FROM exampleTable",
)

BigQuery data source name

The bigquery driver uses the following DSN syntaxes (also known as a connection string):

bigquery://projectid/?param1=value&param2=value
bigquery://projectid/location?param1=value&param2=value

Common BigQuery URL parameters

• dataset - BigQuery dataset ID. When set, you can use unqualified table names in queries.

BigQuery authentication parameters

The Flux BigQuery implementation uses the Google Cloud Go SDK. Provide your authentication credentials using one of the following methods:

• Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to identify the location of your credential JSON file.

• Provide your base-64 encoded service account, refresh token, or JSON credentials using the credentials URL parameter in your BigQuery DSN.

  Example credentials URL parameter

  bigquery://projectid/?credentials=eyJ0eXBlIjoiYXV0...
  

Data type conversion

sql.from() converts BigQuery data types to Flux data types.

BigQuery data type	Flux data type
INTEGER	int
FLOAT, NUMERIC	float
TIMESTAMP	time
BOOLEAN	bool
