Typescript Error

Anyone know why this is happening? I upgraded my drizzle version so maybe something changed?

Any ideas? Was the type changed in newer versions? ;c

Looks like MySqlRawQueryResult is a tuple. The first element response[0] is of type ResultSetHeader which has the affectedRows property. Try response?.[0]?.affectedRows

This worked thank you, where did you find the type? I could not find it in docs anywhere

It's not in the docs as far as I can tell. I searched for MySqlRawQueryResult in the source code

If you import the type like this

import type { MySqlRawQueryResult } from "drizzle-orm/mysql2";

import type { MySqlRawQueryResult } from "drizzle-orm/mysql2";

In VS Code, you can right click and go to type definition.

That shows a type like:

export type MySqlRawQueryResult = [ResultSetHeader, FieldPacket[]];

export type MySqlRawQueryResult = [ResultSetHeader, FieldPacket[]];

And you can keep following the type definitions
