Create Azure Data Catalog-Connected Nintex Workflows

Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with CData Connect Server, you get instant, cloud-to-cloud access to Azure Data Catalog data for business applications. This article shows how to create a virtual database for Azure Data Catalog in Connect Server and build a simple workflow from Azure Data Catalog data in Nintex.

CData Connect Server provides a pure SQL Server interface for Azure Data Catalog, allowing you to build workflows from live Azure Data Catalog data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc.) directly to Azure Data Catalog, leveraging server-side processing to quickly return the requested Azure Data Catalog data.

Create a Virtual SQL Server Database for Azure Data Catalog Data

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

1. Log into Connect Server and click Connections.
2. Select "Azure Data Catalog" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Azure Data Catalog.

   You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

   CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

   Connect Using OAuth Authentication

   You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

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

With the virtual database created, you are ready to connect to Azure Data Catalog data from Nintex.

Connect to Azure Data Catalog in Nintex

The steps below outline creating a new connection for access to Azure Data Catalog CData Connect Server from Nintex to create a new Azure Data Catalog data source.

1. Log into Nintex Workflow Cloud
2. In the Connections tab, click "Add new"
3. Select SQL Server as the connector and click "Connect"
4. In the SQL Server connection wizard, set the following properties:
   • Connection Name: name the connection (e.g., CData Connect Server Azure Data Catalog Connection)
   • Username: your Connect Server username
   • Password: your Connect Server password
   • Database Host: your Connect Server SQL Server endpoint (e.g., connect_server_url)
   • Database Name: the virtual Azure Data Catalog database (e.g., AzureDataCatalog1)
5. Click "Connect"
6. Configure the connection permissions and click "Save permissions"

Create a Simple Azure Data Catalog Workflow

With the connection to CData Connect Server configured, we are ready to build a simple workflow to access Azure Data Catalog data. Start by clicking the "Create workflow" button.

Configure the Start Event Action

1. Click the start event task and select the "Form" event
2. Click "Design form"
3. Drag a "Text - Long" element onto the Form and click the element to configure it
   • Set "Title" to "Enter SQL query"
   • Set "Required" to true
4. Drag a "Text - Short" element onto the Form and click the element to configure it
   • Set "Title" to "Enter desired result column"
   • Set "Required" to true

Configure an "Execute a Query" Action

1. Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
2. Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
3. Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
4. Set "Retrieved column" to a new variable (e.g., "values")

Configure a "Send an Email" Action

1. Add a "Send an email" action after the "Execute a query" action and click to configure the action
2. Set the "Recipient email address"
3. Set the "Subject"
4. Set the "Message body" to the variable created for the retrieved column

Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query Azure Data Catalog using SQL and send an email with the results.
