Sorting by groups

Question

I managed to group my students by phone nbr. But, in these groups I want to sort by name or birthday. As soon as I try to sort by name, I lose my group format. Please help. Thanks
e.g.
jackson, earl
jackson, sandy
smith, bob
smith, edith

Answer 1

select pt.phone_no, p.preferred_name_upper, se.grade,
decode(:p_order1,'A',p.preferred_name_upper,'B',p.birth_date,'C',p.birth_date) order1asc,
decode(:p_order1,'A',pt.phone_no,'B',pt.phone_no,'C',pt.phone_no) order2asc
from student_program_class_tracks spct,
persons p,
school_classes sc,
student_enrolments se,
person_telecom pt
where p.person_id = spct.person_id
and p.person_id = pt.person_id
and se.person_id = p.person_id
and se.school_year = sc.school_year
and se.school_code = sc.school_code
and sc.school_code = spct.school_code
and sc.class_code = spct.class_code
and sc.school_year = spct.school_year
and sc.school_code = 'BRE'
and sc.school_year = '20052006'
and se.school_code = 'BRE'
and se.school_year = '20052006'
and se.grade is not null
and se.active_flag = 'x';
