La requête ci-dessous est tronquée, avec 'created' qui ne montre que 'cre' (faites défiler vers la droite en premier :) :
mysql> SELECT GROUP_CONCAT(CONCAT('<comment><body><![CDATA[',body,']]></body>','<replier>',if(uid is not null,uid,''),'</replier>','<created>',created,'</created></comment>') SEPARATOR '')
-> FROM idiscussion
->
-> WHERE idiscussion.iask_id = 1;
