Azure ODBC Driver

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

Access Azure Table Storage like you would a database - read, write, and update data through a standard ODBC Driver interface.



Create data visualizations with Azure Table data in Power Map.

The CData ODBC Driver for Azure Table is easy to set up and use with self-service analytics solutions like Power BI: Microsoft Excel provides built-in support for the ODBC standard. This article shows how to load the current Azure Table data into Excel and start generating location-based insights on Azure Table data in Power Map.

Create an ODBC Data Source for Azure Table

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.

Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

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 Azure Table Data into Excel

You can import data into Power Map either from an Excel spreadsheet or from Power Pivot. For a step-by-step guide to use either method to import Azure Table data, see the "Using the ODBC Driver" section in the help documentation.

Geocode Azure Table Data

After importing the Azure Table data into an Excel spreadsheet or into PowerPivot, you can drag and drop Azure Table entities in Power Map. To open Power Map, click any cell in the spreadsheet and click Insert -> Map.

In the Choose Geography menu, Power Map detects the columns that have geographic information. In the Geography and Map Level menu in the Layer Pane, you can select the columns you want to work with. Power Map then plots the data. A dot represents a record that has this value. When you have selected the geographic columns you want, click Next.

Select Measures and Categories

You can then simply select columns: Measures and categories are automatically detected. The available chart types are Stacked Column, Clustered Column, Bubble, Heat Map, and Region.
