You don't have any models defined in your schema.prisma, so nothing will be generated.
You can define a model like this:

// Default stuff ... 

model Course {
  id Int @id @default(autoincrement())
  name String
  description String
}

SELECT 
	m.*,
	d.*,
	AVG(r.value) AS rating

JOIN "MapData" AS d ON m."id" = d."mapId"
JOIN "MapRate" AS r ON m."id" = r."mapId"
WHERE deleted = false
GROUP BY m.id, d.id
ORDER BY rating DESC

enum MapPlatform {
  XBOX360 // 1
  PS3 // 2
  PC // 3
}

model Map {
