Prisma batch upsert with raw SQL - sql

Question

I would like to do a batch upsert for a table in postgres. Since prisma doesnt support this in its api, i have to use $executeRaw. I am a little stuck though on how to properly use Prisma.join and Prisma.sql for inserting the data into the template tag.
This post seems to indicate a possible solution: https://github.com/prisma/prisma/discussions/15452#discussioncomment-3737632, however the function signature of Prisma.sql is export declare function sqltag(strings: ReadonlyArray<string>, ...values: RawValue[]): Sql; which indicates it takes two arrays rather than a string.
This is what i have so far:
async function batchUpsertPosts(posts){
await prisma.$executeRaw`INSERT INTO Posts (
feedDomain,
postId,
title,
score,
)
VALUES (), (), ()--... and so on with posts
ON CONFLICT ("feedDomain","postId") DO UPDATE SET score = excluded.score`
}

Answer 1

Ok, I think I managed to figure it out.
async function batchUpsertPosts(posts) {
await prisma.$executeRaw`INSERT INTO "public"."Posts" (
"feedDomain",
"postId",
"title",
"score",
)
VALUES ${Prisma.join(
posts.map(post =>
Prisma.sql`(${post.feedDomain}, ${post.postId}, ${post.title} ,${post.score})`
)
)}
ON CONFLICT ("feedDomain","postId") DO UPDATE SET score = excluded.score`
}
So i just needed to use:
Prisma.sql``
