The SharePoint Adapter models SharePoint entities in relational Tables, Views, and Stored Procedures. The table definitions are dynamically obtained based on your SharePoint site. Any changes you make, such as adding a custom field or changing a field's data type, are automatically reflected when you connect.

Tables

Tables describes the available tables.

Lists in your sharepoint site are exposed as relational tables dynamically. Which means any change you make in your lists, i.e adding new list or adding new fields, will be reflected on the driver.

Views

Views are tables that cannot be modified. Typically, read-only data are shown as views.

Stored Procedures

Stored Procedures are function-like interfaces to the data source. They surface additional capabilities of the SharePoint API such as searching, updating, and modifying information.

Using OData standard

Since the REST API is OData based, server side filters, are done using OData standard. So the driver takes the most of the server filtering, by reading the metadata file and determing which filters can be done on the server.

NOTE: When executing "SELECT *" queries, the SharePoint REST API response, does not return all the available fields. So to avoid too many null values, the provider will select all the columns explicitly using the $select filter. However, the provider will do this only if the $select filter's length is not bigger than 1500, to avoid an error from SharePoint REST API regarding the URL length. This is a limitation of the SharePoint REST API, so in these cases, the only way to see the actual value of some columns, is to explicitly select them in your query.
