GraphQL ODBC Driver

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

Access GraphQL data like you would a database through a standard ODBC Driver interface.



Create data visualizations with GraphQL data in Power Map.

The CData ODBC Driver for GraphQL 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 GraphQL data into Excel and start generating location-based insights on GraphQL data in Power Map.

Create an ODBC Data Source for GraphQL

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.

You must specify the URL of the GraphQL service. The driver supports two types of authentication:

  • Basic: Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.
  • OAuth 1.0 & 2.0: Take a look at the OAuth section in the Help documentation for detailed instructions.

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 GraphQL 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 GraphQL data, see the "Using the ODBC Driver" section in the help documentation.

Geocode GraphQL Data

After importing the GraphQL data into an Excel spreadsheet or into PowerPivot, you can drag and drop GraphQL 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.
