Connect to Asana Data as an External Data Source using PolyBase



Use CData Connect Cloud and PolyBase to create an external data source in SQL Swerver with access to live Asana 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 Asana, you get access to your Asana data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live Asana data using T-SQL queries.

NOTE: PolyBase is only available on SQL Server 19 and above, and only for Standard SQL Server.

CData Connect Cloud provides a pure SQL Server interface for Asana, allowing you to query data from Asana without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Asana, leveraging server-side processing to return the requested Asana data quickly.

Configure Asana Connectivity for PolyBase

Connectivity to Asana from PolyBase is made possible through CData Connect Cloud. To work with Asana data from PolyBase, we start by creating and configuring a Asana connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Asana" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to Asana.

    You can optionally set the following to refine the data returned from Asana.

    • WorkspaceId: Set this to the globally unique identifier (gid) associated with your Asana Workspace to only return projects from the specified workspace. To get your workspace id, navigate to https://app.asana.com/api/1.0/workspaces while logged into Asana. This displays a JSON object containing your workspace name and Id.
    • ProjectId: Set this to the globally unique identifier (gid) associated with your Asana Project to only return data mapped under the specified project. Project IDs can be found in the URL of your project's Overview page. This will be the numbers directly after /0/.

    Connect Using OAuth Authentication

    You must use OAuth to authenticate with Asana. OAuth requires the authenticating user to interact with Asana using the browser. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add Asana Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Create an External Data Source for Asana Data

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

Creating a Credential Database

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

NOTE: Set IDENTITY to your Connect Cloud username and set SECRET to your Personal Access Token.


CREATE DATABASE SCOPED CREDENTIAL ConnectCloudCredentials
WITH IDENTITY = 'yourusername', SECRET = 'yourPAT';

Create an External Data Source for Asana

Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for Asana with PolyBase:


CREATE EXTERNAL DATA SOURCE ConnectCloudInstance
WITH ( 
  LOCATION = 'sqlserver://tds.cdata.com:14333',
  PUSHDOWN = ON,
  CREDENTIAL = ConnectCloudCredentials
);

Create External Tables for Asana

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to Asana data from your SQL Server instance. The table column definitions must match those exposed by CData Connect Cloud. You can use the Data Explorer in Connect Cloud to see the table definition.

Sample CREATE TABLE Statement

Execute a CREATE EXTERNAL TABLE SQL command to create the external table(s), using the collation and setting the LOCATION to three-part notation for the connection, catalog, and table. The statement to create an external table based on a Asana projects would look similar to the following.

CREATE EXTERNAL TABLE projects(
  Id COLLATE [nvarchar](255) NULL,
  WorkspaceId COLLATE [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Asana1.Asana.projects',
  DATA_SOURCE=ConnectCloudInstance
);

Having created external tables for Asana in your SQL Server instance, you are now able to query local and remote data simultaneously. To get live data access to 100+ SaaS, Big Data, and NoSQL sources directly from your SQL Server database, try CData Connect Cloud today!
