Feature request: tagged template raw queries

Hi, looking good so far, but this is a feature that I would like to see, something like this

await db.sql<User & { posts: Post[] }>`
SELECT
    u.*,
    (SELECT json_agg(post) FROM post WHERE user_id = user.id) as posts
FROM user
WHERE id = ${ userId }`

and userId would be escaped automatically. When doing raw queries with bindings as an array at the end it’s quite difficult to keep track on which ? is should correspond to which binding.

Yep, I’ll add a way to use identifiers.

I didn’t want to break anyone’s usecases, that’s why I suggested a separate method.

I don’t want to have two functions that do the same thing. Kysely doesn’t yet have that many users. Now’s the time to break the API if it improves it.

Everything seems cleaner and better with tagged templates 😄

Completely raw query

await db.raw('select * from person where id = ?', [id])

await db.sql`select * from person where id = ${id}`

Subquery

await db
  .selectFrom('person')
  .select(
    db.raw<number>(`(
      select count(pet.id) 
      from pet
      where species = ?
      and pet.owner_id = person.id
    )`, [species]).as('pet_count')
  )

await db
  .selectFrom('person')
  .select(
    db.sql<number>`(
      select count(pet.id) 
      from pet
      where species = ${species}
      and pet.owner_id = person.id
    )`.as('pet_count')
  )

I think we are going to replace raw with the sql tag you suggested in the next version.
