J'essaie d'insérer une simple ligne dans la table. Quelqu'un peut-il préciser ce qui se passe ici?
CREATE TABLE recommendation_engine_poc.user_by_category (
game_category text,
customer_id text,
amount double,
game_date timestamp,
PRIMARY KEY (game_category, customer_id)
) WITH CLUSTERING ORDER BY (customer_id ASC)

SyntaxException: <ErrorMessage code=2000 [Syntax error in CQL query] message="line 1:31 no viable alternative at input 'game_category' (insert into user_by_category (['game_categor]...)">
Mauvaise syntaxe. Vous voilà:
insérer dans user_by_category (game_category, customer_id) VALUES ('Goku', '12');
ou:
insérer dans user_by_category ("game_category", "customer_id") VALUES ('Kakarot', '12');
Le second est normalement utilisé pour les noms de colonnes sensibles à la casse.
