@unique attributes for SQL views (Preview)

Last release, we improved the robustness of SQL views defined in the Prisma schema. Views are virtual tables that don't allows for defining unique constraints, indexes or foreign keys in the underlying database.

However, as an application developer, it can be convenient to also define relationships involving views or paginate them using cursors. We've received this feedback from several people who had been using views in that way with Prisma ORM, so in this release we're re-introducing the @unique attribute for views. This attribute enables:

• relationships involving views
• findUnique queries, cursor-based pagination & implicit ordering for views

Here's an example schema using @unique and defining a relationship from a model to a view:

model User {
  id        Int            @id @default(autoincrement())
  email     String         @unique
  posts     Post[]
  stats     UserPostStats? @relation(fields: [email], references: [userEmail])
}
model Post {
id        Int      @​id @​default(autoincrement())
title     String
published Boolean  @​default(false)
createdAt DateTime @​default(now())
authorId  Int?
author    User?    @​relation(fields: [authorId], references: [id])
}
view UserPostStats {
userEmail        String    @​unique
totalPosts       BigInt?
publishedPosts   BigInt?
unpublishedPosts BigInt?
latestPostDate   DateTime? @​db.Timestamp(6)
user             User?
}

CREATE OR REPLACE VIEW "UserPostStats" AS
SELECT 
</tr></table>
