Warnings:
|
|
|
|
- You are about to drop the column `code_unit` on the `unit_statistics` table. All the data in the column will be lost.
|
|
- A unique constraint covering the columns `[unit_id,month,year]` on the table `unit_statistics` will be added. If there are existing duplicate values, this will fail.
|
|
- A unique constraint covering the columns `[district_id]` on the table `units` will be added. If there are existing duplicate values, this will fail.
|
|
- Made the column `year` on table `crimes` required. This step will fail if there are existing NULL values in that column.
|
|
- Added the required column `unit_id` to the `unit_statistics` table without a default value. This is not possible if the table is not empty.
