tabel pivot mysql dengan nilai string

Tergantung pada versi mysql yang Anda gunakan, inilah satu pendekatan untuk membuat row_number per grup, lalu gunakan conditional aggregation dikelompokkan menurut nomor baris tersebut:

select 
    rn, 
    max(case when stuff = 'bag' then name end) 'bag',
    max(case when stuff = 'book' then name end) 'book',
    max(case when stuff = 'shoes' then name end) 'shoes' 
from (
  select *, row_number() over (partition by stuff order by name) rn
  from stuff_table
) t
group by rn

• Demo Biola

Karena Anda menggunakan mysql versi lama , Anda harus menggunakan user-defined variables untuk menetapkan nomor baris. Sisanya kemudian bekerja sama. Ini contohnya:

select 
    rn, 
    max(case when stuff = 'bag' then name end) 'bag',
    max(case when stuff = 'book' then name end) 'book',
    max(case when stuff = 'shoes' then name end) 'shoes' 
from (
  select *, 
  ( case stuff 
         when @curStuff
         then @curRow := @curRow + 1 
         else @curRow := 1 and @curStuff := stuff 
   end
  ) + 1 AS rn
  from stuff_table, (select @curRow := 0, @curStuff := '') r
  order by stuff
) t
group by rn
