*******ERROR*******

[Err] 1064 - Erreur de syntaxe près de 'if skill_id2=252 then
set i = i+1;
set level2=(select skill_level from ch' à la ligne 26

Sería mejor si usas CASE en vez de anidar IFs.

El error lo tienes porque no has puesto el punto y coma en END IF anterior al IF donde te marca el error.

Gracias!!, ahora me marca este error :
[Err] 1064 - Erreur de syntaxe près de '' à la ligne 50

Error de sintáxis en la línea 50... ¿y cuál es la línea 50?.

Amigo. Será mejor que tomes un curso de SQL porque preguntar cosas como estas da a pensar que estás toqueteando un código que no entiendes.
