ORA-00911 Invalid Character

Bonjour,

Lorsque j'execute ma requète je recois une erreur du type invalid character, mais il ne me signale pas la ligne de cette erreur...
Ma requète faisant plus de 100 lignes je suis en galère...
Quelqu'un à une solution pour avoir le numéro de ligne de l'erreur?

A savoir que sous SQL developper si je lance la requete elle me donne le bon résultat, mais si je la lance en mode "Executer le plan d'execution" la elle plante...

Je travaille avec SQL developper et voilà la requete:
