After introspection my generated schema.prisma file has a lot of this: @db.Char(30) But most examples of the schema I see online does not have this. Should I remove them?

@Josef Henryson 👋 These are native type mappings for your database, so these will be present depending on the data type you have used 🙂

ok, so I should keep them? Why don’t I see them in schema examples?

Yes you should. Schema examples use the default so no annotation is required. Have a look at the defaults as well in that section.
