Używanie MySQL GROUP_CONCAT lub PIVOT na wielu połączonych tabelach

Oto makieta PIVOT zastosowanie rownum do nauczycieli:

select s.col_entry,
  max(case when s.col_inquiry_name = 'Title' then s.col_value end) AS 'Title',
  max(case when s.col_inquiry_name = 'Course' then s.col_value end) AS 'Course',

Edycja nr 1 na podstawie dodatkowego pola, które podałeś col_order możesz go użyć do określenia nauczycieli bez użycia rownum zmienne:

select s.col_entry,
  max(case when s.col_inquiry_name = 'Title' then s.col_value end) AS 'Title',
  max(case when s.col_inquiry_name = 'Course' then s.col_value end) AS 'Course',
  max(case when b.col_inquiry_name = 'Description' then b.col_value end) AS 'Description',
  max(case when d.col_inquiry_name = 'Semester' then d.col_value end) AS 'Semester',
  max(case when s.col_inquiry_name = 'Location' then s.col_value end) AS 'Location',
  max(case when s.col_inquiry_name = 'Teachers'
        and s.col_order = 1 then s.col_value end) AS 'Teachers_01',
  max(case when s.col_inquiry_name = 'Teachers'
        and s.col_order = 2 then s.col_value end) AS 'Teachers_02',
  max(case when s.col_inquiry_name = 'Teachers'
