Ordenar consulta teniendo DATE_FORMAT

[Ribon]

puedes incluir incluir el campo tipo date nuevamente y ordenarlo, así mira

Código MySQL:

SELECT *, DATE_FORMAT(extra_info, '%d-%m-%Y') AS extra_info,  
DATE_FORMAT(registered, '%d-%m-%Y') AS registered,
registered AS to_order
FROM users WHERE 
DATE_SUB(CURDATE(),INTERVAL 60 DAY) >= extra_info  
AND active = 'y' 
AND listaunpu = '0'           
AND access_level >= '2'           
ORDER BY to_order DESC;
