From what i can tell from your create statement I think a join will
get you what you want. Try this--
SELECT Shared.ID, Shared.RawID
JOIN Users ON
(Shared.ID = Users.UserID)
WHERE Users.Login = convert(substring_index(user(),_utf8'@', 1) using latin1);
If that doesn't get you what you are looking for than i have
misunderstood your requirements
