Use the CData ODBC Driver for HPCC Systems in SAS for Real-Time Reporting and Analytics

Connect to real-time HPCC Systems data in SAS for reporting, analytics, and visualizations using the CData ODBC Driver for HPCC Systems.

SAS is a software suite developed for advanced analytics, multivariate analysis, business intelligence, data management, and predictive analytics. When you pair SAS with the CData ODBC Driver for HPCC Systems, you gain database-like access to live HPCC Systems data from SAS, expanding your reporting and analytics capabilities. This articles walks through creating a library for HPCC Systems in SAS and creating a simple report based on real-time HPCC Systems data.

The CData ODBC Driver offers unmatched performance for interacting with live HPCC Systems data in SAS due to optimized data processing built into the driver. When you issue complex SQL queries from SAS to HPCC Systems, the driver pushes supported SQL operations, like filters and aggregations, directly to HPCC Systems and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can easily visualize and analyze HPCC Systems data in SAS.

Connect to HPCC Systems as an ODBC Data Source

Information for connecting to HPCC Systems follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for HPCC Systems must be installed on the machine hosting the SAS System).

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.

Windows

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.

Linux

If you are installing the CData ODBC Driver for HPCC Systems in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData HPCC Sys] Driver = CData ODBC Driver for HPCC Systems Description = My Description URL = http://127.0.0.1:8510 User = test password = xA123456 Version = 1 Cluster = hthor

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a HPCC Systems Library in SAS

Connect to HPCC Systems in SAS by adding a library based on the CData ODBC Driver for HPCC Systems.

  1. Open SAS and expand Libraries in the Explorer pane.
  2. In the Active Libraries window, right-click and select New.
  3. Name your library (odbclib), select ODBC as the Engine, and click to Enable at startup (if you want the library to persist between sessions).
  4. Set Data Source to the DSN you previously configured and click OK.

Create a View from a HPCC Systems Query

SAS natively supports querying data either using a low-code, point-and-click Query tool or programmatically with PROC SQL and a custom SQL query. When you create a View in SAS, the defining query is executed each time the view is queried. This means that you always query live HPCC Systems data for reports, charts, and analytics.

Using the Query Tool

  1. In SAS, click Tools -> Query
  2. Select the table sources and the table(s) you wish to pull data from. Then, click OK.
  3. Select columns and right-click to add filtering, ordering, grouping, etc.
  4. Create a local view to contain the query results by right-clicking the SQL Query Tool window, selecting Show Query, and clicking Create View. Name the View and click OK.

Using PROC SQL

  1. In SAS, navigate to the Editor window.
  2. Use PROC SQL to query the data and create a local view.
    NOTE: This procedure creates a view in the Work library. You can optionally specify a library in the create view statement.
    proc sql;
      create view hpcc::test::orders_view as
      select 
        customername, 
        price 
      from 
        odbclib.hpcc::test::orders 
      where 
        ShipCity = 'New York';
    quit;
    
  3. Click Run -> Submit to execute the query and create a local view.

Report On or Visualize HPCC Systems Data in SAS

With a local view created, you can report, visualize, or otherwise analyze HPCC Systems data using the powerful SAS features. Print a simple report using PROC PRINT and create a basic graph based on the data using PROC GCHART.

Print an HTML Report

  1. In SAS, navigate to the Editor window.
  2. Use PROC PRINT to print an HTML report for the HPCC Systems hpcc::test::orders data.
    proc print data=hpcc::test::orders;
      title "HPCC Systems hpcc::test::orders Data";
    run;
    

Print a Chart

  1. In SAS, navigate to the Editor window.
  2. Use PROC GCHART to create a chart for the hpcc::test::orders data.
    proc gchart data=hpcc::test::orders;
      pie customername / sumvar=price
          value=arrow
          percent=arrow
          noheading
          percent=inside plabel=(height=12pt)
          slice=inside value=none
          name='hpcc::test::ordersChart';
    run;
