     *
     * @param where the `where` clause.
     *
     * @example
     * You can use conditional operators and `sql function` to filter the rows to be deleted.
     *
     * ```ts
     * // Delete all cars with green color

     * await db.delete(cars).where(sql`${cars.color} = 'green'`)
     * ```
     *
     * You can logically combine conditional operators with `and()` and `or()` operators:
     *
     * ```ts
     * // Delete all BMW cars with a green color
     * await db.delete(cars).where(and(eq(cars.color, 'green'), eq(cars.brand, 'BMW')));
     *
     * // Delete all cars with the green or blue color

     *
     * See docs: {@link https://orm.drizzle.team/docs/delete#delete-with-return}
     *
     * @example
