Spécification de lasource de données
Accédez aux paramètres généraux d'une spécification de source de données existante. Pour accéder à la spécification de la source de données pour un type donné, utilisez la méthode as...(). Pour créer une spécification de source de données, utilisez SpreadsheetApp.newDataSourceSpec().
N'utilisez cette classe que pour les données connectées à une base de données.
Cet exemple montre comment obtenir des informations à partir d'une spécification de source de données BigQuery.
Cet exemple montre comment obtenir des informations à partir d'une spécification de source de données Looker. L'utilisation de asLooker() renvoie un objet LookerDataSourceSpec.
