Use CData Connect Server to connect to SQL Analysis Services from Nintex Workflow Cloud and build custom workflows using live SQL Analysis Services 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 Server, you get instant, cloud-to-cloud access to SQL Analysis Services data for business applications. This article shows how to create a virtual database for SQL Analysis Services in Connect Server and build a simple workflow from SQL Analysis Services data in Nintex.
CData Connect Server provides a pure SQL Server interface for SQL Analysis Services, allowing you to build workflows from live SQL Analysis Services 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 SQL Analysis Services, leveraging server-side processing to quickly return the requested SQL Analysis Services data.
Create a Virtual SQL Server Database for SQL Analysis Services Data
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Log into Connect Server and click Connections.
- Select "SQL Analysis Services" from Available Data Sources.
-
Enter the necessary authentication properties to connect to SQL Analysis Services.
To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.
To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.
-
HTTP Authentication
Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.
-
Windows (NTLM)
Set the Windows User and Password and set AuthScheme to "NTLM".
-
Kerberos and Kerberos Delegation
To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.
-
SSL/TLS:
By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.
You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.
See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.
-
HTTP Authentication
- Click Save Changes
- 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 SQL Analysis Services data from Nintex.
Connect to SQL Analysis Services in Nintex
The steps below outline creating a new connection for access to SQL Analysis Services CData Connect Server from Nintex to create a new SQL Analysis Services data source.
- Log into Nintex Workflow Cloud
- In the Connections tab, click "Add new"
- Select SQL Server as the connector and click "Connect"
- In the SQL Server connection wizard, set the following properties:
- Connection Name: name the connection (e.g., CData Connect Server SQL Analysis Services 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 SQL Analysis Services database (e.g., SSAS1)
- Click "Connect"
- Configure the connection permissions and click "Save permissions"
Create a Simple SQL Analysis Services Workflow
With the connection to CData Connect Server configured, we are ready to build a simple workflow to access SQL Analysis Services 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 (e.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 SQL Analysis Services using SQL and send an email with the results.
