Create an RPA Flow that Connects to HPCC Systems Data in UiPath Studio

Use the HPCC Systems ODBC Driver to create workflows that access real-time HPCC Systems data without any coding.

UiPath is a Robotic Process Automation (RPA) platform with rich features and an easy-to-use UI that enables non-developers to create process automation. By using UiPath Studio, you can build an RPA program just like drawing a diagram. With the CData ODBC Driver for HPCC Systems, users can embed HPCC Systems data in the workflow.

This article walks through using the HPCC Systems ODBC Driver in UiPath Studio to create an RPA program that accesses HPCC Systems data.

Configure the Connection to HPCC Systems

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

Set Cluster to the target cluster.

Connect UiPath Studio to HPCC Systems Data

Now you are ready to use HPCC Systems data ODBC DSN in UiPath Studio with the following steps.

  1. From the Start page, click Blank to create a New Project.
  2. Click Manage Packages then search for and install UiPath.Database.Activities.
  3. Navigate to the Activities and drop a Flowchart (Workflow -> Flowchart -> Flowchart) onto the process.
  4. Drop a database Connect activity (App Integration -> Datbase -> Connect) after the Start activity.
  5. Double-click the Connect activity and configure the Connection.
    1. Click the Connection Wizard
    2. Select "Microsoft ODBC Data Source"
    3. In Connection Properties, select your DSN (CData HPCC Source) and click OK
  6. To store Connection info, create a variable and bind to Output in the Properties section. Choose DatabaseConnection in Output.

Create an Execute Query Activity

With the connection configured, we are ready to query HPCC Systems data in our RPA.

  1. From the Activities navigation, select Execute Query and drop it on the Flowchart.
  2. Double-click the Execute Query activity and set the properties as follows:
    • ExistingDbConnection: Your Connection variable
    • Sql: SELECT statement like SELECT SUM(hpcc::test::orders.Price), hpcc::test::customers.CustomerName FROM hpcc::test::orders INNER JOIN hpcc::test::customers ON hpcc::test::orders.CustomerId=hpcc::test::customers.CustomerId;GROUP BY hpcc::test::customers.CustomerName
    • DataTable: Create and use a variable with the Type System.Data.DataTable

Create Write CSV Activity

With the Connection and Execute Query activities configured, we are ready to add a Write CSV activity to the Flowchart to replicate the HPCC Systems data.

  1. From the Activities navigation, select Write CSV and drop it after the Execute Query activity.
  2. Double-click the Write CSV activity and set the properties as follows:
    • FilePath: Set to a file (new or existing) on disk (i.e.: C:\UiPath[id]-data.csv
    • DataTable: Set to the DataTable variable you created earlier

Connect the Activities and Run the Flowchart

If they are not already connected, connect each Activity that you created to complete the RPA project for extracting HPCC Systems data and exporting it to CSV.

Click Run to extract HPCC Systems data and create a CSV file.
