HPCC ODBC Driver

The HPCC ODBC Driver is a powerful tool that allows you to connect with live HPCC Systems data, directly from any applications that support ODBC connectivity.

Access HPCC Systems like you would a database - query data through a standard ODBC Driver interface.



Create data visualizations with HPCC Systems data in Power Map.

The CData ODBC Driver for HPCC Systems is easy to set up and use with self-service analytics solutions like Power BI: Microsoft Excel provides built-in support for the ODBC standard. This article shows how to load the current HPCC Systems data into Excel and start generating location-based insights on HPCC Systems data in Power Map.

Create an ODBC Data Source for 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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Import HPCC Systems Data into Excel

You can import data into Power Map either from an Excel spreadsheet or from Power Pivot. For a step-by-step guide to use either method to import HPCC Systems data, see the "Using the ODBC Driver" section in the help documentation.

Geocode HPCC Systems Data

After importing the HPCC Systems data into an Excel spreadsheet or into PowerPivot, you can drag and drop HPCC Systems entities in Power Map. To open Power Map, click any cell in the spreadsheet and click Insert -> Map.

In the Choose Geography menu, Power Map detects the columns that have geographic information. In the Geography and Map Level menu in the Layer Pane, you can select the columns you want to work with. Power Map then plots the data. A dot represents a record that has this value. When you have selected the geographic columns you want, click Next.

Select Measures and Categories

You can then simply select columns: Measures and categories are automatically detected. The available chart types are Stacked Column, Clustered Column, Bubble, Heat Map, and Region.
