/*
  Warnings:

  - The primary key for the `Booking` table will be changed. If it partially fails, the table could be left without primary key constraint.
  - You are about to drop the column `billId` on the `Booking` table. All the data in the column will be lost.
  - The `id` column on the `Booking` table would be dropped and recreated. This will lead to data loss if there is data in the column.
  - A unique constraint covering the columns `[bookingId]` on the table `Bill` will be added. If there are existing duplicate values, this will fail.
  - Added the required column `bookingId` to the `Bill` table without a default value. This is not possible if the table is not empty.
