How can I, if possible, read back and present data (formerly logged to DB) from SQL or Oracle DB in the 800xA HMI?
I want the possibility to log data to a DB by using SDL or PDL, and for convenience I want the possibilty to display them in the HMI for the operator to see. I also wonder if SDL-logging only can log to a MS SQL-server and the PDL only to Oracle, or if the two can coexist on the same DB-server.

It is possible to log PDL data using 800xA system IM facilities.
Also, 800xA contain tools to access data related to PDL - desktop trends and data direct. And, of course, these data can be displayed on HMI.
I'm not sure you can log PDL in MS SQL and I've never seen 2 different database management systems running on the same server simultaneously. At least I haven't seen such solutions... but I'm not stand for that. In fact, it is possible.
