I want to update a metadata column in sharepoint online library. The column should be updated based on the data in sql db.For example i need to update a field named student status,i should check what is the status of the student for some x id and that status need to be updated in sharepoint online document library. Please suggest me the ways. Thanks in advance.
Develop a custom application (e.g. a .NET Console Application) or use Microsoft Flow to create your SQL/SHAREPOINT integration. Flow has connectors for many platforms including SharePoint and SQL Server. Trigger your flow on a schedule or when a student row is created or updated in SQL.
If your SQL Server in installed on-premises then you also need the Microsoft on-premises data gateway for Flow to access the data there.
Using Flow might incur additional costs - check the available pricing plans for Microsoft flow.
