Pb de requete SQL avec clauses WHERE dans une procédure stockée

Version imprimable

Bonjour à tous,

J'ai créé une procédure stockée qui permet de calculer les points gagnées entre deux relevés de points. Et je me suis rendu compte que lorsque je fais un SELECT avec des clauses WHERE, certaines ne sont pas pris en compte et notemment les paramètres d'entrées de ma procédure.
Voici le code de la procédure :

Ce que je comprend pas c'est que j'ai le bon résultat avec un copier coller du SELECT de la procédure stockée.

Je pense que ça vient de la déclaration de mes paramètres, mais je vois pas ce qui ne va pas.

Quelqu'un aurai une idée d'où cela vient ?

merci d'avance

J'ai modifié ma procédure et j'ai fini par laisser un seul SELECT. Mais j'ai toujours le même résultat. Voici le code :

C'est bon je viens de trouver d'où vient mon problème. Cela vient bien des paramètres qui ont les même noms que celui des tables.
