The connector models the OneDrive API as relational tables. Any changes to the remote data are immediately reflected in your queries; the table definitions are dynamically retrieved. When you connect, the connector connects to OneDrive and gets the list of tables and the metadata for the tables by calling the appropriate Web services.
- The connector models OneDrive entities like Files and Folders as relational views, allowing you to write SQL to query OneDrive data.
- Stored procedures allow you to execute operations to OneDrive, including retrieving the access token and keeping it refreshed in OAuth 2.0.
- Live connectivity to these objects means any changes to your OneDrive account are immediately reflected when using the connector.
Views shows definitions from a sample OneDrive site. The actual data model will be obtained dynamically based on your user credentials and site.
Stored Procedures are function-like interfaces to OneDrive. They can be used to search, update and modify information in OneDrive.
Collaborative Query Processing
The connector offloads as much of the SELECT statement processing as possible to OneDrive and then processes the rest of the query in memory (client-side).
This is done through the SupportEnhancedSQL property, which is enabled by default. You can disable it in order to turn off client-side execution. This will return the information unfiltered, so the results might be incorrect.
