Use the CData ODBC Driver for Cosmos DB in SAS JMP

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

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

Access Cosmos DB 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 obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

  • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
  • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.

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 Cosmos DB Data with the Query Builder

After you have created the Cosmos DB DSN, you can use SQL to invoke the capabilities of the Cosmos DB 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 Cosmos DB 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 CosmosDB Source;", "INSERT INTO Customers (Name) VALUES ('Morris Park Bake Shop');");

Visualize Cosmos DB 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, City.
  2. Drag a measure column onto the y axis. For example, CompanyName.
  3. Select a chart type. For example, a bar chart.
