i have 2 tables - “Server messages” and “Registered servers”.
And i need to show only these messages, which come from servers included in registered servers.
Server01 — ok
Server02 — bad
Server03 — ok
User will see only: Server02 — bad
(because Server02 is in registered table)
Please, im struggling with it for a long time, do you know, how to do that?
Thank you so much.
