IBM Informix ODBC Driver

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

Access IBM Informix data like you would a database - read, write, and update IBM Informix databases through a standard ODBC Driver interface.



You can use the CData ODBC Driver to integrate IBM Informix data into the statistical analysis tools available in SAS JMP. This article shows how to use IBM Informix data in the Graph Builder and Query Builder.

You can use the CData ODBC Driver for IBM Informix to integrate live data into your statistical analysis with SAS JMP. The driver proxies your queries directly to the IBM Informix API, ensuring that your analysis reflects any changes to the data. The CData ODBC Driver supports the standard SQL used by JMP in the background as you design reports.

The IBM Informix API supports bidirectional access. This article shows how to access IBM Informix data into a report and create data visualization. It also shows how to use SQL to query and manipulate IBM Informix data from the JMP Query Builder.

Access IBM Informix Data as an ODBC Data Source

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.

Set the following properties to connect to IBM Informix

  • Server: Set this to the name of the server running IBM Informix.
  • Port: Set this to the port the IBM Informix server is listening on.
  • Database: Set this to the name of the IBM Informix database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

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 IBM Informix Data with the Query Builder

After you have created the IBM Informix DSN, you can use SQL to invoke the capabilities of the IBM Informix API. Follow the steps below to execute some supported queries in the Query Builder:

  1. In SAS JMP, click File -> Database -> Query Builder. The Select Database Connection dialog is displayed.
  2. Click New Connection.
  3. On the Machine Data Source tab, select the DSN. In the next step, the Select Tables for Query dialog is displayed.
  4. In the Available Tables section, select a table and click Primary.
  5. As you drag Available Columns to the Included Columns tab, the underlying SQL query is updated.
  6. Click Run Query to display the data.
  7. To refresh the results with the current data, right-click Update from Database and click Run Script.

Manipulate IBM Informix Data

You can execute data manipulation queries from JSL scripts such as the one below. To execute a script, click New Script in the toolbar. To connect, specify the DSN. You can then use the standard SQL syntax:

Open Database( "DSN=CData Informix Source;", "INSERT INTO Books (Category) VALUES ('US');");

Visualize IBM Informix Data

After importing, you can use the Graph Builder to create graphs visually. To open the Graph Builder, click the Graph Builder button in the toolbar.

  1. Drag a dimension column onto the x axis. For example, Id.
  2. Drag a measure column onto the y axis. For example, Price.
  3. Select a chart type. For example, a bar chart.
