Prepared statement contains too many placeholders – MySQL error

See original GitHub issue

Discussed in https://github.com/prisma/prisma/discussions/15508

<div type='discussions-op-text'>

Originally posted by honzapav September 25, 2022 Hello, I have a query (see below), and I am getting an error: Prepared statement contains too many placeholders. I understand that there are limits on the MySQL database, but I don’t know how to overcome them. What is the best practice in this case.

I use Prisma 4.3.1.

Thank you. H.

The error message from redis

This query is implemented in NestJS API in Bull query. I got this message from redis. The query works as expected when I read less data (thousands of rows of shop_products).

@janpio Hello, please find the project dump here: https://drive.google.com/file/d/12z075ZkFTpIFO7PY0w_mChHqpjFbdbMg/view?usp=sharing.

It was quite easy to anonymize so I can share it. I have tested this dump, and the error persists. Please let me know if you have any further information. Many thanks!
