Create IBM Cloud Data Engine-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 IBM Cloud Data Engine data for business applications. This article shows how to create a virtual database for IBM Cloud Data Engine in Connect Server and build a simple workflow from IBM Cloud Data Engine data in Nintex.

CData Connect Server provides a pure SQL Server interface for IBM Cloud Data Engine, allowing you to build workflows from live IBM Cloud Data Engine 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 IBM Cloud Data Engine, leveraging server-side processing to quickly return the requested IBM Cloud Data Engine data.

Create a Virtual SQL Server Database for IBM Cloud Data Engine 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 "IBM Cloud Data Engine" from Available Data Sources.
3. Enter the necessary authentication properties to connect to IBM Cloud Data Engine.

   IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

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 IBM Cloud Data Engine data from Nintex.

Connect to IBM Cloud Data Engine in Nintex

The steps below outline creating a new connection for access to IBM Cloud Data Engine CData Connect Server from Nintex to create a new IBM Cloud Data Engine 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 IBM Cloud Data Engine 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 IBM Cloud Data Engine database (e.g., IBMCloudDataEngine1)
5. Click "Connect"
6. Configure the connection permissions and click "Save permissions"

Create a Simple IBM Cloud Data Engine Workflow

With the connection to CData Connect Server configured, we are ready to build a simple workflow to access IBM Cloud Data Engine 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 IBM Cloud Data Engine using SQL and send an email with the results.
