Use the CData ODBC Driver for Greenplum in SAS JMP



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

You can use the CData ODBC Driver for Greenplum to integrate live data into your statistical analysis with SAS JMP. The driver proxies your queries directly to the Greenplum 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 Greenplum API supports bidirectional access. This article shows how to access Greenplum data into a report and create data visualization. It also shows how to use SQL to query and manipulate Greenplum data from the JMP Query Builder.

Access Greenplum 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.

To connect to Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the default database for the authenticate user is used.

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 Greenplum Data with the Query Builder

After you have created the Greenplum DSN, you can use SQL to invoke the capabilities of the Greenplum 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 ODBC DSN you configured and then click Next.
  4. The Select Tables for Query dialog is displayed and in the Available Tables section, select a table and click Primary. After choosing the primary table, click Build Query to open the Query Builder.
  5. As you drag Available Columns to the Included Columns tab, the underlying SQL query is updated and you can view the generated SQL Query in the SQL tab.
  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 Greenplum 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 Greenplum Source;", "INSERT INTO Orders (ShipCountry) VALUES ('USA');");

Visualize Greenplum 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, Freight.
  2. Drag a measure column onto the y axis. For example, ShipName.
  3. Select a chart type. For example, a bar chart.
