Je travaille un script pour porter un environnement d'un serveur à un autre. Je rencontre un problème d'appel catalog.create_environment_variabledans lequel j'obtiens l'erreur "Le type de données de la valeur d'entrée n'est pas compatible avec le type de données de la" chaîne "." sortant du proc "check_data_type_value".
Ce qui est étrange, c'est que si je laisse le script GUI sortir les variables, cette requête fonctionnera
DECLARE @var sql_variant = N'\\myserver\ssisdata'
EXEC [catalog].[create_environment_variable]
@variable_name = N'FolderBase'
, @sensitive = False
, @description = N''
, @environment_name = N'Development'
, @folder_name = N'POC'
, @value = @var
, @data_type = N'String'
GO
Cependant, adopter cette approche de script ne fonctionne pas. Le travail que j'ai fait indique que ce message d'erreur est généralement résolu en utilisant le type de données nvarchar au lieu de varchar. Cependant, ce n'est pas le cas pour mes affaires.
Ligne 108 pour le script suivant. Mon hypothèse est que c'est quelque chose de loufoque avec la sql_variant mais je n'ai aucune idée de ce qu'est cette chose.
