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

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 SAS xpt, you gain database-like access to live SAS xpt data from SAS, expanding your reporting and analytics capabilities. This article explains how to create a library for SAS xpt in SAS and create a simple report based on real-time SAS xpt data.

The CData ODBC Driver offers unmatched performance for interacting with live SAS xpt data in SAS due to optimized data processing built into the driver. When you issue complex SQL queries from SAS to SAS xpt, the driver pushes supported SQL operations, like filters and aggregations, directly to SAS xpt 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 SAS xpt data in SAS.

Connect to SAS xpt as an ODBC Data Source

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

Connecting to Local SASXpt Files

You can connect to local SASXpt file by setting the URI to a folder containing SASXpt files.

Connecting to S3 data source

You can connect to Amazon S3 source to read SASXpt files. Set the following properties to connect:

• URI: Set this to the folder within your bucket that you would like to connect to.
• AWSAccessKey: Set this to your AWS account access key.
• AWSSecretKey: Set this to your AWS account secret key.
• TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

Connecting to Azure Data Lake Storage Gen2

You can connect to ADLS Gen2 to read SASXpt files. Set the following properties to connect:

• URI: Set this to the name of the file system and the name of the folder which contacts your SASXpt files.
• AzureAccount: Set this to the name of the Azure Data Lake storage account.
• AzureAccessKey: Set this to our Azure DataLakeStore Gen 2 storage account access key.
• TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

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 SAS xpt 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 SASXpt Sys]
Driver = CData ODBC Driver for SAS xpt
Description = My Description
URI = C:/folder

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

Create a SAS xpt Library in SAS

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

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. 👁 Creating a library for SAS xpt in SAS.
   

Create a View from a SAS xpt 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 SAS xpt 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. 👁 Selecting table(s) to visualize.
   
3. Select columns and right-click to add filtering, ordering, grouping, etc. 👁 Selecting columns(s) to visualize and configuring the query.
   
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. 👁 Create a local view to work with SAS xpt data.
   

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 sampletable_1_view as
    select 
    id, 
    column1 
    from 
    odbclib.sampletable_1 
    where 
    Column2 = '100';
   quit;
   

3. Click Run -> Submit to execute the query and create a local view.

Report On or Visualize SAS xpt Data in SAS

With a local view created, you can report, visualize, or otherwise analyze SAS xpt 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 SAS xpt SampleTable_1 data.

   proc print data=sampletable_1;
    title "SAS xpt SampleTable_1 Data";
   run;

Print a Chart

1. In SAS, navigate to the Editor window.
2. Use PROC GCHART to create a chart for the SampleTable_1 data.

   proc gchart data=sampletable_1;
    pie id / sumvar=column1
    value=arrow
    percent=arrow
    noheading
    percent=inside plabel=(height=12pt)
    slice=inside value=none
    name='SampleTable_1Chart';
   run;
