sparql requests in protege

hello, sparql requests in protege
I need to find 100 names mail.ru

PREFIX foaf: <https://mail.ru/>
SELECT? X? Name
WHERE {? X foaf: name? Name} LIMIT 100

does not produce the required answer
advise what to do
thank you in advance

looks like broken or oddball sql, not c++.

what does it produce? Do you have select access for this information on that server?

hello, thanks for the feedback
I have my diploma work, sparql inquiries in the protege
I want to make a request in the sparql program
100 names need someone who has vk.com
but you need to find in this https://www.yahoo.com/ site


PREFIX foaf: < https://www.yahoo.com/>
SELECT ?name ?mbox
WHERE
{ ?x foaf:name ?name .
?x foaf:mbox ?mbox }

can customize protege?
