-- 安全迁移脚本：从第一个版本迁移到当前版本
|
||
-- 此脚本保留所有现有数据，使用中间表处理主键变更
|
||
|
||
-- ====================================
|
||
-- 步骤1: 使用中间表迁移 Device 表
|
||
-- ====================================
|
||
|
||
-- 1.1 创建新的 Device_new 表，使用目标结构
|
||
CREATE TABLE `Device_new` (
|
||
`id` INT NOT NULL AUTO_INCREMENT,
|
||
`uuid` VARCHAR(191) NOT NULL,
|
||
`password` VARCHAR(191) NULL,
|
||
`passwordHint` VARCHAR(191) NULL,
|
||
`name` VARCHAR(191) NULL,
|
||
`accountId` VARCHAR(191) NULL,
|
||
`accessType` ENUM('PUBLIC', 'PROTECTED', 'PRIVATE') NOT NULL DEFAULT 'PUBLIC',
|
||
`createdAt` DATETIME(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3),
|
||
`updatedAt` DATETIME(3) NOT NULL,
|
||
|
||
PRIMARY KEY (`id`),
|
||
UNIQUE INDEX `Device_uuid_key`(`uuid`)
|
||
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
||
|
||
-- 1.2 从旧表迁移数据到新表（自动分配id）
|
||
INSERT INTO `Device_new` (`uuid`, `password`, `passwordHint`, `name`, `accessType`, `createdAt`, `updatedAt`)
|
||
SELECT `uuid`, `password`, `passwordHint`, `name`, `accessType`, `createdAt`, `updatedAt`
|
||
FROM `Device`
|
||
ORDER BY `uuid`;
|
||
|
||
-- ====================================
|
||
-- 步骤2: 使用中间表迁移 KVStore 表
|
||
-- ====================================
|
||
|
||
-- 2.1 创建新的 KVStore_new 表，使用目标结构
|
||
CREATE TABLE `KVStore_new` (
|
||
`deviceId` INT NOT NULL,
|
||
`key` VARCHAR(191) NOT NULL,
|
||
`value` JSON NOT NULL,

||
-- 2.2 从旧表迁移数据到新表（通过uuid映射到id）
|
||
INSERT INTO `KVStore_new` (`deviceId`, `key`, `value`, `creatorIp`, `createdAt`, `updatedAt`)
|
||
SELECT d.`id`, k.`key`, k.`value`, k.`creatorIp`, k.`createdAt`, k.`updatedAt`
|
||
FROM `KVStore` k
|
||
INNER JOIN `Device_new` d ON k.`namespace` = d.`uuid`;
|
||
|
||
-- 2.3 删除旧表
|
||
DROP TABLE `KVStore`;
|
||
|
||
-- 2.4 重命名新表
|
||
RENAME TABLE `KVStore_new` TO `KVStore`;
|
||
|
||
-- ====================================
|
||
-- 步骤3: 完成 Device 表迁移
|
||
-- ====================================
|
||
|
||
-- 3.1 删除旧的 Device 表
|
||
DROP TABLE `Device`;
|
||
|
||
-- 3.2 重命名新表
|
||
RENAME TABLE `Device_new` TO `Device`;
|
||
|
||
-- 3.3 为 KVStore 添加外键约束（必须在两个表都重命名后）
|
||
ALTER TABLE `KVStore` ADD CONSTRAINT `KVStore_deviceId_fkey`
|
||
FOREIGN KEY (`deviceId`) REFERENCES `Device`(`id`) ON DELETE CASCADE ON UPDATE CASCADE;
|
||
|
||
-- ====================================
|
||
-- 步骤4: 创建 App 表
|
||
-- ====================================
|
||
|
||
CREATE TABLE `App` (
|
||
`id` INT NOT NULL AUTO_INCREMENT,
|
||
`name` VARCHAR(191) NOT NULL,
|
||

||
`updatedAt` DATETIME(3) NOT NULL,
|
||
|
||
PRIMARY KEY (`id`)
|
||
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
||
|
||
-- ====================================
|
||
-- 步骤5: 创建 AppInstall 表
|
||
-- ====================================
|
||
|
||
CREATE TABLE `AppInstall` (

|
||

|
||
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
||
|
||
-- 5.1 添加外键约束
|
||
ALTER TABLE `AppInstall` ADD CONSTRAINT `AppInstall_deviceId_fkey`
|
||
FOREIGN KEY (`deviceId`) REFERENCES `Device`(`id`) ON DELETE CASCADE ON UPDATE CASCADE;
|
||
|
