Use CData Connect Cloud to connect to PostgreSQL Data from Nintex Workflow Cloud and build custom workflows using live PostgreSQL data.
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 Cloud, you get instant, cloud-to-cloud access to PostgreSQL data for business applications. This article shows how to create a virtual database for PostgreSQL in Connect Cloud and build a simple workflow from PostgreSQL data in Nintex.
CData Connect Cloud provides a pure, cloud-to-cloud interface for PostgreSQL, allowing you to build workflows from live PostgreSQL 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 Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to PostgreSQL, leveraging server-side processing to quickly return the requested PostgreSQL data.
Configure PostgreSQL Connectivity for Nintex
Connectivity to PostgreSQL from Nintex is made possible through CData Connect Cloud. To work with PostgreSQL data from Nintex, we start by creating and configuring a PostgreSQL connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "PostgreSQL" from the Add Connection panel
-
Enter the necessary authentication properties to connect to PostgreSQL.
To connect to PostgreSQL, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the data provider connects to the user's default database.
- Click Create & Test
- Navigate to the Permissions tab in the Add PostgreSQL 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.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured, you are ready to connect to PostgreSQL data from Nintex Workflow Cloud.
Connect to PostgreSQL from Nintex
The steps below outline creating a new connection to PostgreSQL data from Nintex (via Connect Cloud).
- Log into Nintex Workflow Cloud
- In the Connections tab, click "Add new"
- Select "Microsoft SQL Server" as the connector and click "Connect"
- In the SQL Server connection wizard, set the following properties:
- Connection Name: a Connect Cloud
- Username: a Connect Cloud username (e.g. [email protected])
- Password: the Connect Cloud user's PAT
- Database Host: tds.cdata.com
- Database Name: the PostgreSQL connection (a.g., PostgreSQL1)
- Click "Connect"
- Configure the connection permissions and click "Save permissions"
Create a Simple PostgreSQL Workflow
With the connection to CData Connect Cloud configured, we are ready to build a simple workflow to access PostgreSQL data. Start by clicking the "Create workflow" button.
Configure the Start Event Action
- Click the start event task and select the "Form" event
- Click "Design form"
- 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
- 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
- Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
- Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
- Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
- Set "Retrieved column" to a new variable (a.g., "values")
Configure a "Send an Email" Action
- Add a "Send an email" action after the "Execute a query" action and click to configure the action
- Set the "Recipient email address"
- Set the "Subject"
- 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 PostgreSQL using SQL and sand an email with the results.
