SAS Data Sets ODBC Driver

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

Access SAS Data Sets data like you would a database - read, write, and update through a standard ODBC Driver interface.



Create an ODBC connection to SAS Data Sets in Informatica and browse and transfer SAS Data Sets data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for SAS Data Sets, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse SAS Data Sets data in Informatica PowerCenter.

Connect to SAS Data Sets as an ODBC Data Source

Information for connecting to SAS Data Sets follows, along with different instructions for configuring a DSN in Windows and Linux environments.

Set the following connection properties to connect to your SAS DataSets files:

  • URI: Set this to the folder containing your .sas7bdat resources. Currently we only support local files.

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 Data Sets 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 SASDataSets Source] Driver = CData ODBC Driver for SAS Data Sets Description = My Description URI = C:/myfolder

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

Create a Linked Table to restaurants Data

Follow the steps below to create a linked table, which enables you to access live restaurants data.

Create the ODBC Connection

Follow the steps below to connect to SAS Data Sets in Informatica PowerCenter:

  1. In the Informatica Developer tool connect to your repository and create a project.
  2. In the Connection Explorer pane, right-click and click Create a Connection.
  3. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select ODBC.
  4. In the Connection String property, enter the DSN.

NOTE: If you are working in a Linux operating system, set the Driver Manager for Linux property to unixODBC 2.3.x.

Create the SAS Data Sets Data Object

After you have created an ODBC connection to SAS Data Sets, you can now access SAS Data Sets entities in Informatica. Follow the steps below to add restaurants entities to your project.

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. In the wizard that is displayed, select the Relational Data Object option.
  3. Click the Browse button next to the Connection box and select the ODBC connection you created in the previous step.
  4. Select the option to create a data object from an existing resource and click the Browse button next to the Resource box.
  5. In the dialog that is displayed, clear the Show Default Schema Only option and expand the node for the ODBC connection. Select the entity that you want.

You can now browse the table in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

Create the Mapping

Follow the steps below to add the SAS Data Sets source to a mapping:

  1. In the Object Explorer, right-click your project and then click New -> Mapping.
  2. Expand the node for the SAS Data Sets connection and then drag the data object for the table onto the editor.
  3. In the dialog that appears, select the Read option.

Follow the steps below to map SAS Data Sets columns to a flat file:

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
  3. In the properties for the SAS Data Sets object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
  4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
  5. Click and drag to connect columns.

To transfer SAS Data Sets data, right-click in the workspace and then click Run Mapping.
