Integrate Snowflake Data into Automated Tasks with Microsoft Flow

Use the CData Cloud Hub to create a virtual SQL Server database for Snowflake data and integrate live Snowflake data into your Microsoft Flow tasks.

Microsoft Flow is an online workflow service that automates events (known as workflows) across the most common apps and services. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to Snowflake data for visualizations, dashboards, and more. This article shows how to connect to the Cloud Hub from Microsoft Flow and integrate live Snowflake data into your workflows and tasks.

The CData Cloud Hub provides a pure SQL, cloud-to-cloud interface for Snowflake, allowing you to easily integrate with live Snowflake data in Microsoft Flow — without replicating the data. The CData Cloud Hub looks exactly like a SQL Server database to Microsoft Flow and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Snowflake, leveraging server-side processing to quickly return Snowflake data.

Create a Virtual SQL Database for Snowflake Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "Snowflake" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Snowflake.

    To connect to Snowflake:

    1. Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
    2. Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
    3. Set Warehouse to the Snowflake warehouse.
    4. (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
    5. (Optional) Set Database and Schema to restrict the tables and views exposed.

    See the Getting Started guide in the CData driver documentation for more information.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connecting to the CData Cloud Hub

To use the Cloud Hub to integrate Snowflake data into your Flow tasks, you need a new SQL Server connection:

  1. Log in to Microsoft Flow
  2. Click Data -> Connections -> New connection
  3. Select SQL Server
  4. In the connection wizard:

    • Choose to connect directly
    • Set SQL server name to the address of your Cloud Hub instance (myinstance.cdatacloud.net)
    • Set SQL database name to the name of the virtual Snowflake database you created earlier (like snowflakedb)
    • Set the Username and Password and click Create

Integrating Snowflake Data into MS Flow Tasks

With the connection to the Cloud Hub configured, you are ready to integrate live Snowflake data into your Microsoft Flow tasks.

  1. Log in to Microsoft Flow
  2. Click My flows -> New and choose to create the flow from blank or template
  3. Add (or configure) a SQL Server action (like Get rows) and configure the action to connect to your Cloud Hub connection
  4. Select a Table to work with (from the drop-down menu) and configure any advanced options (like filters, orders, etc)
  5. Configure any actions to follow and test, then save the flow

SQL Access to Snowflake Data from Cloud Applications

Now you have a direct connection to live Snowflake data from Microsoft Flow tasks. You can create more connections and workflows to drive business — all without replicating Snowflake data.

To get SQL data access to 100+ SaaS, Big Data, and NoSQL sources directly from your cloud applications, see the CData Cloud Hub.
