/*
  Warnings:

  - A unique constraint covering the columns `[certificateNumber]` on the table `Certificate` will be added. If there are existing duplicate values, this will fail.
  - A unique constraint covering the columns `[userId,courseId]` on the table `Certificate` will be added. If there are existing duplicate values, this will fail.
  - Added the required column `certificateNumber` to the `Certificate` table without a default value. This is not possible if the table is not empty.
