Bonjour à tous,
J'utilise SQL Server Management Studio Express 2005.
Je voudrais avoir un champ qui contienne un texte saisi par un utilisateur, dont qui puisse contenir au moins 500 caractères.
J'ai essayé nvarchar(MAX) mais c'est limité à 50 caractères environ !!!
Je ne suis pas arrivé à trouver le bon type de champ. Quelqu'un aurait-il une idée ??
Merci bien :)
voici les types existant, tu pourrais essayer avec ceux en rouge :
