MySQL Query to get age from date of birth

Question

I have an issue with my query,

SELECT id, pseudo, nom, prenom, sexe, ville, 
       FLOOR(DATEDIFF (NOW(), date_naissance)/365) AS mAge 
FROM user 
WHERE sexe         


        

Answer 1

You can not use column aliases in WHERE clauses: http://dev.mysql.com/doc/refman/5.0/en/problems-with-alias.html.

You will have to rethink your query or change to:

SELECT id, pseudo, nom, prenom, sexe, ville, 
   FLOOR(DATEDIFF (NOW(), date_naissance)/365) AS mAge 
FROM user 
WHERE sexe = 'Homme' AND 
FLOOR(DATEDIFF (NOW(), date_naissance)/365) BETWEEN 18 AND 25 
OR ville = 'Bordeaux'

Ps you may also want to have a look at your ANDs and ORs as well as you might want to include some brackets.
