[ARGCIS 9.3] Probleme avec la fonction select
Bonjour à tous,
J'ai créé un modèle sous modelbuilder qui fonctionne.
J'essaie de le passer sous python et je rencontre une erreur que je n'arrive pas à solutionner. Au moment de réaliser la sélection, j'ai l'erreur suivante :
Error executing function
An expected Field was not found or could not be retrieved properly.
[pt.MIN_POINT_]
A locator with this name does not exist
Failed to execute.
Pourtant l'expression de la condition dans ma fonction select est juste et fonctionne sous modelbuilder.
Je pense qu'au moment de l'export ou dans python, certains caractères ne sont plus lisibles. Du coup, lors du déroulement du script, certains champs ne sont plus trouvables.
Voici mon code en Python.
