See this announcement from Microsoft regarding their decision to undeprecate OLE DB: Announcing the new release of OLE DB Driver for SQL Server. Announcement date: October 6, 2017.
I’ve been poking at SAP for when they will update their support for SQL Server OLEDB now that Microsoft has released an updated driver for SQL Server 2018 but I couldn’t get an answer from them.
I was finally got an answer last month but they are not stating they will update their support. They are recommending leveraging the ODBC driver. Or we could use the JDBC driver. Neither of these perform as well as OLEDB of course.
