Describe the Bug

Default value is being inserted into the MySQL Auto Increment Column for insert statement. Below is the code to reproduce the issue.

import Database from 'better-sqlite3';
import { drizzle as sqlite_drizzle } from 'drizzle-orm/better-sqlite3';
import { int, mysqlTable, varchar } from "drizzle-orm/mysql-core";
import { drizzle } from "drizzle-orm/mysql2";
import { integer, sqliteTable, text } from "drizzle-orm/sqlite-core";
import mysql from "mysql2/promise";

const sqlite3_users = sqliteTable('user', {
  id: integer('id', { mode: 'number' }).primaryKey({ autoIncrement: true }),
  name: text('name')
});

const mysql_users = mysqlTable("user", {
    id: int("id").primaryKey().autoincrement(),
    name: varchar("name", { length: 30 }).default('').notNull(),
});

async function main() {
    const connection = await mysql.createConnection({
        uri:"mysql://admin:admin@localhost:3306/drizzle_sample",
    });
  const db = drizzle(connection);
  const query = await db.insert(mysql_users).values({
    name: "Hello, World!",
  }).toSQL()

  console.log(query.sql);
}
async function sqlite_run() {
const sqlite = new Database('sqlite.db');
const db = sqlite_drizzle(sqlite);
const query = await db.insert(sqlite3_users).values({
  name: "Hello, World!",
}).toSQL()

console.log(query.sql);
}

async function run() {
  await main();
  await sqlite_run();
}

run();

The output on the console is as follows.

insert into `user` (`id`, `name`) values (default, ?) # MySQL
insert into "user" ("id", "name") values (null, ?) # sqlite3

Why insert statement set default for ai column id ? Anyone else encountered this issue or mysql schema defination was wrong? Any comments will be gratefully appreciated, thanks in advance.

Expected behavior

insert into user (id, name) values (null, ?) # MySQL

or

insert into user (name) values (?) # MySQL
