SQL-Question

Hello! I have an exercise here with two tables from an library. The first one shows the colums: articleNr, media, title, who owns it now The second one: user ID,name, last name, adress. The user ID and the ,,who ownes it now‘‘ are the primary key and they show who ownes the book now. So now i my exercise: Who ones the most media right now. What is the SQL command for this Question?

functions command help select sql,

Since you want to know "who owns it" and you already know who owns it now, just "count" how many "media" is owned and I would "group it" by name.Good luck David.
