So I got the Entity framework to work with this oracle database that I am working on. However, when I created the emdx file, everything is fine but I get a tons of about 100 warning, in which there is a lot of error 6002 says the table/view doesnt have primary key defined. Key has been inferred and the definition was created as read-only. How am I going to fix this? And does this mean I cannot insert or modify the data in these tables with this warning?
