Using COUNT in GROUP_CONCAT

Question

This is my table:

  id  | fk_company
-------------------
  1   |     2    
  2   |     2    
  3   |     2    
  4   |     4    
  5   |     4    
  6   |     11          


        

Answer 1

SELECT A,  
GROUP_CONCAT(B SEPARATOR '/') AS 'Category',  
GROUP_CONCAT(C SEPARATOR '/') AS 'ALIAS_NAME',COUNT('ALIAS_NAME') AS 'Count'  
FROM carnews  
...  
...
GROUP BY 1
ORDER BY 4 DESC  

This works well in my case.
