en cherchant quelques syntaxe sur ISQL je suis tomber sur ceci
Currently it is possible to create databases in Dialect 1 and 3 only, however it is recommended that you use
Dialect 3 exclusively, since Dialect 1 will eventually be deprecated. Dialect 2 cannot be used to create a database
since it only serves to convert Dialect 1 to Dialect 3.
Quelqu'un aurait-il des informations sur cette utilisation du DIALECT 2 ?
