.raw doesn't return data if query doesn't start with SELECT statement

I’m using the Prisma Beta2 with Postgres and prisma.raw and am getting a panic error when trying to do a recursive query.

I have the following schema

model Task {
  id String @default(cuid()) @ id
  parent Task? @relation("TaskTree", fields: [parentId], references: [id])
  parentId String?
  children Task[]  @relation("TaskTree")
}

I need to get all descendants of a given node referenced via it’s id. The following sql gets me the results I need. It works perfectly fine in postgres.

          WITH RECURSIVE descendants AS (
              SELECT *
              FROM "Task"
              WHERE id = '${id}'
          UNION ALL
              SELECT t.*
              FROM "Task" t
              JOIN descendants ON t."parentId" = descendants.id
          )
          SELECT * FROM descendants;

However, when I plug it into prisma.raw I get the Error: PANIC: expected 0 parameters but got 1

Here’s my error logs:

Am I also correct in assuming this query can’t be done with graphql?

Edit: The same query is working fine with https://node-postgres.com/

We’ve decided to go ahead and deprecate raw in favor of these two separate methods (one for query, another for execute) as suggested by @pimeys.

Naming of the two methods is still TBD.

Update:

• naming: we’ve decided to go with queryRaw and executeRaw.
• existing raw method: will be removed in favor of these two new dedicated methods.
