Membuat kombinasi tabel/kolom menggunakan SQL Query atau Laravel SQL Query Builder

Ini harus melakukannya. Tidak akan berfungsi di mysql 5.7 karena CTE rekursif tidak disertakan sampai nanti, tetapi ini akan memungkinkan Anda untuk memiliki sejumlah variabel atribut dan nilai_atribut per group_id. Biola di sini .

with recursive allAtts as (
  /* Get our attribute list, and format it if we want; concat(a.title, ':', v.title) looks quite nice */
  SELECT 
    att.group_id,
    att.id,
    CONCAT(v.title) as attDesc,
    dense_rank() over (partition by att.group_id order by att.id) as attRank
FROM table_attributes att 
INNER JOIN table_attribute_values v 
    ON v.group_id = att.group_id 
    AND v.attribute_id = att.id 
 ),
 cte as (
 /* Recursively build our attribute list, assuming ranks are sequential and we properly linked our group_ids */
    select group_id, id, attDesc, attRank from allAtts WHERE attRank = 1
   
         union all 
   
    select 
        allAtts.group_id, 
        allAtts.id, 
        concat_ws('-', cte.attDesc, allAtts.attDesc) as attDesc,
        allAtts.attRank
   from cte 
   join allAtts ON allAtts.attRank = cte.attRank +1
      AND cte.group_id = allAtts.group_id
)
   
/* Our actual select statement, which RIGHT JOINs against the table_groups 
   so we don't lose entries w/o attributes */   
select 
    grp.id,
    concat_ws('-', d.day, qty.quantity, cte.attDesc) as combinations
from cte 
inner join (select group_id, max(attRank) as attID
            from cte
            group by group_id) m on cte.group_id = m.group_id and m.attID = cte.attrank
RIGHT JOIN table_groups grp ON grp.id = cte.group_id 
LEFT JOIN table_days d on grp.id = d.group_id
LEFT JOIN table_quantities qty on grp.id = qty.group_id;
