With demo data, when I open the FormsTool, click on "Formulaire de contact" and then "See SQL query", the generated query is :

SELECT id as Id, creationDate as 'null', Ametys_Gen_1 as 'Saisissez votre nom', Ametys_Gen_2 as 'Adresse e-mail', Ametys_Gen_3 as 'Objet du message', Ametys_Gen_4 as 'Saisissez votre message'
FROM Forms_form_05203847671908659;

It does not work. It should be " instead of '
It should be in the helper for datasources (to be centralized)

What's more, creationDate as 'null' is invalid
