  /**
   * Adds an `on duplicate key update` clause to the query.
   *
   * Calling this method will update the row if any unique index conflicts. MySQL will automatically determine the conflict target based on the primary key and unique indexes.
   *
   * See docs: {@link https://orm.drizzle.team/docs/insert#on-duplicate-key-update}
   *
   * @param config The `set` clause
   *
   * @example
   * ```ts
   * await db.insert(cars)
   *   .values({ id: 1, brand: 'BMW'})
   *   .onDuplicateKeyUpdate({ set: { brand: 'Porsche' }});
   * ```
   *
   * While MySQL does not directly support doing nothing on conflict, you can perform a no-op by setting any column's value to itself and achieve the same effect:
   *
   * ```ts
   * import { sql } from 'drizzle-orm';
   *
   * await db.insert(cars)
   *   .values({ id: 1, brand: 'BMW' })
   *   .onDuplicateKeyUpdate({ set: { id: sql`id` } });
   * ```
