Raw bulk insert failing

Bug description

I’m attempting to do a bulk raw insert. This is to avoid having to loop through every record, as this has performance implications. I need the IDs from the initial bulk insert as I then need to update other tables, and as per what’s discussed here, createMany does not return the inserted rows.

I have spoken to a Prisma Engineer about this, and have attempted to use the code he supplied me with (which, he says, was working for him).

See: https://github.com/prisma/prisma/issues/8131#issuecomment-1237992626

How to reproduce

I am running the following code, in Nest.js:

const rows = [{ status: 's' }, { status: 'x' }];

const values = rows.map((row) => Prisma.sql`(${row.status})`);

await this.prismaService
  .$queryRaw`INSERT INTO "test" (status) VALUES ${Prisma.join(
  values,
)} RETURNING *`;

When I run the above, I get the following error back:

prisma:query SELECT 1
prisma:query INSERT INTO "test" (status) VALUES $1 RETURNING *

That was me. I wasn’t able to locally reproduce the problem though. https://prisma.slack.com/archives/CA491RJH0/p1662461878343699

I’m having the same issue. I had to move to queryRawUnsafe.

this is my code that fails

prisma.$queryRaw`INSERT INTO "l_intent" ("english") VALUES ${Prisma.join(
          englishes.map(english => `($E$${english}$E$)`)
        )} RETURNING *`

the error is:

error - PrismaClientKnownRequestError: 
Invalid `prisma.$queryRaw()` invocation:


  Raw query failed. Code: `42601`. Message: `db error: ERROR: syntax error at or near "$1"`
    at Object.request (/Users/noitidart/Documents/The-App/web/node_modules/@prisma/client/runtime/index.js:45405:15)

    message: 'db error: ERROR: syntax error at or near "$1"'
  },
  page: '/api/v1/l/admin/projects/upload'
}

It’s interesting because if I run this code it works just fine:

prisma.$queryRaw`INSERT INTO "l_intent" ("english") VALUES ($E$don't do it$E$),($E$build with spaces$E$) RETURNING *`

I’m currently using queryRawUnsafe:

prisma.$queryRawUnsafe(
          `INSERT INTO "l_intent" ("english") VALUES ${englishes
            .map(english => `($E$${english}$E$)`)
            .join(', ')} RETURNING *`
        )
