/*
  Warnings:

  - The primary key for the `Stock_Balance` table will be changed. If it partially fails, the table could be left without primary key constraint.
  - You are about to alter the column `quantity` on the `Stock_Balance` table. The data in that column could be lost. The data in that column will be cast from `Decimal(10,2)` to `Decimal(14,3)`.
  - You are about to alter the column `totalCost` on the `Stock_Balance` table. The data in that column could be lost. The data in that column will be cast from `Decimal(10,2)` to `Decimal(14,2)`.
  - You are about to alter the column `avgCost` on the `Stock_Balance` table. The data in that column could be lost. The data in that column will be cast from `Decimal(10,2)` to `Decimal(14,2)`.
  - A unique constraint covering the columns `[productId,inventoryId]` on the table `Stock_Balance` will be added. If there are existing duplicate values, this will fail.
  - Added the required column `id` to the `Stock_Balance` table without a default value. This is not possible if the table is not empty.
