Select * from student where id in
(select id from student where count(*) > 1 group by fname, lname)
(select id from student where count(*) > 1 group by fname, lname)
Or...
Select s1.* from student s1 where exists
(select 1 from student s2 where s2.fname = s1.fname and s2.lname = f1.lname and s1.id <> s2.id)
Select s1.* from student s1 where exists
(select 1 from student s2 where s2.fname = s1.fname and s2.lname = f1.lname and s1.id <> s2.id)
