Connect to YouTube as an External Data Source using PolyBase

Use the CData ODBC Driver for YouTube and PolyBase to create an external data source in SQL Server 2019 with access to live YouTube data.

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for YouTube, you get access to your YouTube data directly alongside your SQL Server data. This article walks through creating an external data source and external tables to grant access to live YouTube data using T-SQL queries.

The CData ODBC drivers offer unmatched performance for interacting with live YouTube data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to YouTube, the driver pushes down supported SQL operations, like filters and aggregations, directly to YouTube and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. And with PolyBase, you can also join SQL Server data with YouTube data, using a single query to pull data from distributed sources.

Connect to YouTube

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData YouTube Sys is created automatically).

YouTube uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded CData credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

Click "Test Connection" to ensure that the DSN is connected to YouTube properly. Navigate to the Tables tab to review the table definitions for YouTube.

Create an External Data Source for YouTube Data

After configuring the connection, you need to create a master encryption key and a credential database for the external data source.

Creating a Master Encryption Key

Execute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.


Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to YouTube data.

NOTE: Since YouTube does not require a User or Password to authenticate, you may use whatever values you wish for IDENTITY and SECRET.

WITH IDENTITY = 'username', SECRET = 'password';

Create an External Data Source for YouTube

Execute the following SQL command to create an external data source for YouTube with PolyBase, using the DSN and credentials configured earlier.

For YouTube, set SERVERNAME to 'localhost' or '' and leave PORT empty. PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.

CREATE EXTERNAL DATA SOURCE cdata_youtube_source
  CREDENTIAL = youtube_creds

Create External Tables for YouTube

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to YouTube data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for YouTube. You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

Sample CREATE TABLE Statement

The statement to create an external table based on a YouTube Videos would look similar to the following:

  Title [nvarchar](255) NULL,
  ViewCount [nvarchar](255) NULL,
) WITH ( 

Having created external tables for YouTube in your SQL Server instance, you are now able to query local and remote data simultaneously. Thanks to built-in query processing in the CData ODBC Driver, you know that as much query processing as possible is being pushed to YouTube, freeing up local resources and computing power.
