Allow select as alias custom field name and exclude some fields in prisma client

Problem

In prisma client 2.26 and sqlite, its not every efficient to run map, reduce server side functions to rename keys in data from prisma.

If prisma is getting upwards of five different relations, I would rather directly setup aliases, custom field names directly in the query than external code

similarly, if a table has a lot of field names, theres no clear way to exclude few while selecting all others.

I dont want to explicitly name every field in the prisma query if I need to select only 24 out of 25 fields in the model relation

Suggested solution

I am looking for the prisma equivalent of

SELECT party_id as id FROM genres 

and

SELECT * EXCEPT id
FROM (...) genres

and somehow apply it across multiple relations in findMany starting example

var tv_shows = await prisma.tVShow.findMany({
    include: { genres: true, production_companies: true, seasons: { include: { episodes: true } }, credits: true, similar: true }
  })

Alternatives

Doing an external code implementation using map, reduce to transform the selected object
ie

genres.map(item => {item.id = item.party_id; delete item.id;})

I don’t know if it is the same issue, but I would love to be able to alias (rename) relations as well.

For example, what I would love:

const customer = await prisma.customer.findUnique({
  where { id },
  select: {
    fruits: {
      select: { id: true },
      where: { type: 'banana' },
      as: 'bananas'
    }
  }
})

// Bananas !
customer.bananas
