Note: If a model has mandatory Unsupported fields, the generated client will not include create or update methods for that model. Oh sorry, I have just skimmed through your issue, didn't see you use native types. Defines a unique constraint for this field. bug/1-unconfirmed Bug should have enough information for reproduction, but confirmation has not happened yet. I think as MySQL (and PostgreSQL for that matter) support timezone-agnostic DATE datatypes it would be obvious that prisma supports these as well. Because it makes UTC time as fake date data and always need conversion mutually, These patches make anyone confused or annoyed . Composite types are currently only available on MongoDB. The data model definition part of the Prisma schema defines your application models (also called Prisma models).

Ouput Datetime fields as string in GraphQL query using Sequelize. Using UTC / specifying timezone is a huge over complication, its simpler to just store it as a string. See Using custom model and field names to see how @map and @@map changes the generated Prisma Client. The data source connector determines what native database type each of Prisma scalar type maps to. When you introspect a relational database, unsupported types are added as Unsupported : The Unsupported attribute allows you to define fields in the Prisma schema for database types that are not yet supported by Prisma.
