|
||||
func (m *Migrator) Migrate(steps int) error // 执行指定数量迁移
|
||||
```
|
||||
|
||||
### 2. 迁移定义 (`pkg/migration/migrations.go`)
|
||||
|
||||
**已定义迁移:**
|
||||
- `20250101_000001`: 创建基础表 (user, category, photo)

||||
db-restore # 恢复备份 (需要 BACKUP=file)
|
||||
```
|
||||
|
||||
## 🛡️ 安全特性
|
||||
|
||||
### 1. 事务安全
|
||||
- 每个迁移在独立事务中执行
|
||||
- 失败时自动回滚
|
||||
- 状态记录原子性更新
|
||||
|
||||
### 2. 自动备份
|
||||
- 生产环境迁移前自动备份
|
||||
- 时间戳命名，易于识别
|
||||
- 快速恢复机制
|
||||
|
||||
### 3. 预览模式
|
||||
- 支持 "干跑" 模式
|

|
||||
|
||||
## 🚀 SQLite 优化
|
||||
|
||||
### 1. 字段删除处理
|
||||
SQLite 不支持 `DROP COLUMN`，系统使用表重建模式:
|
||||
```sql
|
||||
-- 创建新表结构
|
||||
CREATE TABLE table_new (...);
|
||||
-- 复制数据
|
||||
INSERT INTO table_new SELECT ... FROM table;
|
||||
-- 删除旧表
|
||||
DROP TABLE table;
|
||||
-- 重命名
|
||||
ALTER TABLE table_new RENAME TO table;
|
||||
```
|
||||
|
||||
### 2. 幂等性保证
|
||||
```sql
|
||||
-- 使用 IF NOT EXISTS 和 OR IGNORE
|
||||
CREATE TABLE IF NOT EXISTS table (...);
|
||||
ALTER TABLE table ADD COLUMN IF NOT EXISTS field VARCHAR(255);
|
||||
INSERT OR IGNORE INTO table VALUES (...);
|
||||
```
|
||||
|
||||
### 3. 索引管理
|
||||
```sql
|
||||
-- 安全的索引创建
|
||||
CREATE INDEX IF NOT EXISTS idx_name ON table(field);
|
||||
```
|
||||
|
||||
## 📊 测试验证

# 数据库迁移系统文档
|
||||
|
||||
## 📋 概述
|
||||
|
||||
本项目使用自定义的数据库迁移系统，支持版本控制、回滚、备份等完整的数据库管理功能。该系统专为 SQLite 优化，同时兼容 MySQL 和 PostgreSQL。
|
||||
|
||||
## 🏗️ 系统架构
|
||||
|
||||
### 核心组件
|
||||
|
||||
```
|
||||
pkg/migration/
|
||||
├── migration.go # 迁移管理器核心逻辑
|
||||
├── migrations.go # 所有迁移定义
|
||||
└── README.md # 迁移开发指南
|
||||
|
||||
cmd/migrate/
|
||||
└── main.go # 命令行工具
|
||||
|
||||
scripts/
|
||||
├── production-migrate.sh # 生产环境迁移脚本
|
||||
└── init-production-db.sh # 生产环境初始化脚本
|
||||
```
|
||||
|
||||
### 迁移记录表
|
||||
|
||||
系统会自动创建 `schema_migrations` 表来跟踪迁移状态：
|
||||
|
||||
```sql
|
||||
CREATE TABLE schema_migrations (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
version VARCHAR(255) UNIQUE NOT NULL,
|
||||
description VARCHAR(500),
|
||||
applied BOOLEAN DEFAULT FALSE,
|
||||
applied_at TIMESTAMP,
|
||||
created_at TIMESTAMP,
|
||||
updated_at TIMESTAMP
|
||||
);
|
||||
```
|
||||
|
||||
## 🚀 快速开始
|
||||
|
||||
### 1. 开发环境初始化
|
||||
|
||||
```bash
|
||||
# 初始化数据库（全新安装）
|
||||
make db-init
|
||||
|
||||
# 查看迁移状态
|
||||
make migrate-status
|
||||
|
||||
# 手动运行所有迁移
|
||||
make migrate-up
|
||||
```
|
||||
|
||||
### 2. 生产环境部署
|
||||
|
||||
```bash
|
||||
# 全新生产环境初始化
|
||||
./scripts/init-production-db.sh
|
||||
|
||||
# 生产环境迁移
|
||||
./scripts/production-migrate.sh migrate
|
||||
|
||||
# 预览模式（不实际执行）
|
||||
./scripts/production-migrate.sh -d migrate
|
||||
```
|
||||
|
||||

|
||||
```
|
||||
|
||||
## 📝 迁移开发
|
||||
|
||||
### 迁移命名规范
|
||||
|
||||
```
|
||||
版本号格式: YYYYMMDD_HHMMSS
|
||||
示例: 20250111_120000
|
||||
|
||||
描述规范:
|
||||
- 动词开头: Create, Add, Update, Remove, Drop
|
||||
- 清晰简洁: Create user table, Add email index
|
||||
- 避免缩写: 使用完整单词
|
||||
```
|
||||
|
||||
### 创建新迁移
|
||||
|
||||
#### 方法1: 使用 Makefile
|
||||
|
||||
```bash
|
||||
make migrate-create NAME="add_user_avatar_field"
|
||||
```
|
||||
|
||||
#### 方法2: 手动添加到 migrations.go
|
||||
|
||||
```go
|
||||
{
|
||||
Version: "20250111_120000",
|
||||
Description: "Add avatar field to user table",
|
||||
Timestamp: time.Date(2025, 1, 11, 12, 0, 0, 0, time.UTC),
|
||||
UpSQL: `
|
||||
ALTER TABLE user ADD COLUMN avatar VARCHAR(255) DEFAULT '';
|
||||
CREATE INDEX IF NOT EXISTS idx_user_avatar ON user(avatar);
|
||||
`,
|
||||
DownSQL: `
|
||||
DROP INDEX IF EXISTS idx_user_avatar;
|
||||
-- SQLite 不支持 DROP COLUMN，需要重建表
|
||||
CREATE TABLE user_temp AS SELECT id, username, password, email, status, created_at, updated_at FROM user;
|
||||
DROP TABLE user;
|
||||
ALTER TABLE user_temp RENAME TO user;
|
||||
`,
|
||||
},
|
||||
```
|
||||
|
||||
### 迁移编写最佳实践
|
||||
|
||||
#### 1. UP 迁移 (向前)
|
||||
|
||||
```sql
|
||||
-- ✅ 好的做法
|
||||
ALTER TABLE user ADD COLUMN IF NOT EXISTS avatar VARCHAR(255) DEFAULT '';
|
||||
CREATE INDEX IF NOT EXISTS idx_user_avatar ON user(avatar);
|
||||
INSERT OR IGNORE INTO category (name) VALUES ('新分类');
|
||||
|
||||
-- ❌ 避免的做法
|
||||
ALTER TABLE user ADD COLUMN avatar VARCHAR(255); -- 没有 IF NOT EXISTS
|
||||
CREATE INDEX idx_user_avatar ON user(avatar); -- 没有 IF NOT EXISTS
|
||||
INSERT INTO category (name) VALUES ('新分类'); -- 没有 OR IGNORE
|
||||
```
|
||||
|
||||
#### 2. DOWN 迁移 (回滚)
|
||||
|
||||
```sql
|
||||
-- SQLite 回滚模式（重建表）
|
||||
CREATE TABLE user_temp (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
username VARCHAR(50) UNIQUE NOT NULL,
|
||||
password VARCHAR(255) NOT NULL,
|
||||
email VARCHAR(100) UNIQUE NOT NULL,
|
||||
-- 注意：不包含新添加的 avatar 字段
|
||||
status INTEGER DEFAULT 1,
|
||||
created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
|
||||
updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
|
||||
);
|
||||
|
||||
INSERT INTO user_temp (id, username, password, email, status, created_at, updated_at)
|
||||
SELECT id, username, password, email, status, created_at, updated_at FROM user;
|
||||
|
||||
DROP TABLE user;
|
||||
ALTER TABLE user_temp RENAME TO user;
|
||||
|
||||
-- 重新创建索引
|
||||
CREATE INDEX IF NOT EXISTS idx_user_username ON user(username);
|
||||
CREATE INDEX IF NOT EXISTS idx_user_email ON user(email);
|
||||
```
|
||||
|
||||
#### 3. 数据迁移
|
||||
|
||||
```sql
|
||||
-- 安全的数据迁移
|
||||
UPDATE user SET status = 1 WHERE status IS NULL OR status = 0;
|
||||
UPDATE photo SET category_id = 1 WHERE category_id IS NULL;
|
||||
|
||||
-- 避免危险操作
|
||||
-- DELETE FROM user; -- 危险！不要直接删除数据
|
||||
```
|
||||
|
||||
## 🔒 安全性和生产环境
|
||||
|
||||
### 备份策略
|
||||
|
||||
1. **自动备份**: 每次迁移前自动创建备份
|
||||
2. **定期备份**: 通过 cron 定期备份
|
||||
3. **备份验证**: 定期验证备份文件完整性
|
||||
|
||||
```bash
|
||||
# 创建定期备份 cron 任务
|
||||
0 2 * * * cd /path/to/project && make db-backup
|
||||
|
||||
# 验证备份
|
||||
sqlite3 backup.db ".tables" > /dev/null && echo "备份正常" || echo "备份损坏"
|
||||
```
|
||||
|
||||
### 生产环境部署流程
|
||||
|
||||
#### 1. 预生产测试
|
||||
|
||||
```bash
|
||||
# 1. 在测试环境验证迁移
|
||||
./scripts/production-migrate.sh -d migrate
|
||||
|
||||
# 2. 执行测试迁移
|
||||
./scripts/production-migrate.sh migrate
|
||||
|
||||
# 3. 验证功能正常
|
||||
make test
|
||||
|
||||
# 4. 回滚测试
|
||||
./scripts/production-migrate.sh rollback 1
|
||||
```
|
||||
|
||||
#### 2. 生产部署
|
||||
|
||||
```bash
|
||||
# 1. 备份生产数据库
|
||||
./scripts/production-migrate.sh backup
|
||||
|
||||
# 2. 执行迁移
|
||||
./scripts/production-migrate.sh migrate
|
||||
|
||||
# 3. 验证迁移结果
|
||||
./scripts/production-migrate.sh status
|
||||
|
||||
# 4. 重启应用服务
|
||||
sudo systemctl restart photography-api
|
||||
```
|
||||
|
||||
#### 3. 回滚计划
|
||||
|
||||
```bash
|
||||
# 如果出现问题，立即回滚
|
||||
./scripts/production-migrate.sh rollback 1
|
||||
|
||||
# 或者恢复备份
|
||||
./scripts/production-migrate.sh restore backup_filename.db
|
||||
```
|
||||
|
||||
### 监控和日志
|
||||
|
||||
```bash
|
||||
# 查看迁移日志
|
||||
tail -f migration.log
|
||||
|
||||
# 监控应用日志
|
||||
tail -f backend.log
|
||||
|
||||
# 系统状态检查
|
||||
./scripts/production-migrate.sh check
|
||||
```
|
||||
|
||||
## 🛠️ 故障排除
|
||||
|
||||
### 常见问题
|
||||
|
||||
#### 1. 迁移失败
|
||||
|
||||
```bash
|
||||
# 查看错误详情
|
||||
go run cmd/migrate/main.go -c status
|
||||
|
||||
# 检查数据库连接
|
||||
sqlite3 data/photography.db ".tables"
|
||||
|
||||
# 恢复到最近备份
|
||||
make db-restore BACKUP=latest_backup.db
|
||||
```
|
||||
|
||||
#### 2. 版本冲突
|
||||
|
||||
```bash
|
||||
# 手动标记迁移为已应用
|
||||
sqlite3 data/photography.db "UPDATE schema_migrations SET applied = 1 WHERE version = '20250111_120000';"
|
||||
|
||||
# 或者重置迁移状态
|
||||
make migrate-reset
|
||||
make migrate-up
|
||||
```
|
||||
|
||||
#### 3. SQLite 限制
|
||||
|
||||
SQLite 不支持的操作和解决方案：
|
||||
|
||||
```sql
|
||||
-- ❌ SQLite 不支持
|
||||
ALTER TABLE user DROP COLUMN old_field;
|
||||
ALTER TABLE user MODIFY COLUMN name VARCHAR(100);
|
||||
|
||||
-- ✅ 解决方案：重建表
|
||||
CREATE TABLE user_new (...);
|
||||
INSERT INTO user_new SELECT ... FROM user;
|
||||
DROP TABLE user;
|
||||
ALTER TABLE user_new RENAME TO user;
|
||||
```
|
||||
|
||||
### 紧急恢复
|
||||
|
||||
#### 1. 完全重置
|
||||
|
||||
```bash
|
||||
# 备份当前数据
|
||||
cp data/photography.db data/emergency_backup.db
|
||||
|
||||
# 重置数据库
|
||||
make migrate-reset
|
||||
|
||||
# 重新初始化
|
||||
make db-init
|
||||
```
|
||||
|
||||
#### 2. 数据恢复
|
||||
|
||||
```bash
|
||||
# 从备份恢复数据
|
||||
sqlite3 data/photography.db "
|
||||
.read backup_data.sql
|
||||
"
|
||||
|
||||
# 或者使用工具恢复
|
||||
./scripts/production-migrate.sh restore backup_file.db
|
||||
```
|
||||
|
||||
## 📊 性能优化
|
||||
|
||||
### 大型迁移优化
|
||||
|
||||
```sql
|
||||
-- 分批处理大量数据
|
||||
UPDATE user SET new_field = 'default' WHERE id BETWEEN 1 AND 1000;
|
||||
UPDATE user SET new_field = 'default' WHERE id BETWEEN 1001 AND 2000;
|
||||
-- ...
|
||||
|
||||
-- 使用事务
|
||||
BEGIN TRANSACTION;
|
||||
-- 批量操作
|
||||
COMMIT;
|
||||
```
|
||||
|
||||
### 索引策略
|
||||
|
||||
```sql
|
||||
-- 先删除索引，再批量更新，最后重建索引
|
||||
DROP INDEX IF EXISTS idx_user_email;
|
||||
-- 批量更新操作
|
||||
CREATE INDEX idx_user_email ON user(email);
|
||||
```
|
||||
|
||||
## 📋 最佳实践总结
|
||||
|
||||
### ✅ 推荐做法
|
||||
|
||||
1. **版本控制**: 每个迁移都有唯一版本号
|
||||
2. **可回滚**: 每个 UP 迁移都有对应的 DOWN 迁移
|
||||
3. **幂等性**: 使用 `IF NOT EXISTS` 和 `OR IGNORE`
|
||||
4. **备份**: 生产环境迁移前自动备份
|
||||
5. **测试**: 在测试环境验证迁移
|
||||
6. **监控**: 记录迁移日志和状态
|
||||
|
||||
### ❌ 避免做法
|
||||
|
||||
1. **直接修改**: 不要直接修改生产数据库
|
||||
2. **删除迁移**: 不要删除已应用的迁移文件
|
||||
3. **跳过版本**: 不要跳过中间版本
|
||||
4. **无备份**: 不要在没有备份的情况下迁移
|
||||
5. **大事务**: 避免长时间锁表的大事务

# Migration Package Documentation
|
||||
|
||||
## 概述
|
||||
|
||||
这是摄影作品集项目的数据库迁移包，提供了完整的数据库版本管理和迁移功能。
|
||||
|
||||
## 快速开始
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"photography-backend/pkg/migration"
|
||||
"photography-backend/pkg/utils/database"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// 创建数据库连接
|
||||
db, err := database.NewDB(dbConfig)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
// 创建迁移器
|
||||
migrator := migration.NewMigrator(db)
|
||||
|
||||
// 添加迁移
|
||||
migrations := migration.GetAllMigrations()
|
||||
for _, m := range migrations {
|
||||
migrator.AddMigration(m)
|
||||
}
|
||||
|
||||
// 执行迁移
|
||||
if err := migrator.Up(); err != nil {
|
||||
panic(err)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## API 参考
|
||||
|
||||
### Migrator
|
||||
|
||||
#### 创建迁移器
|
||||
|
||||
```go
|
||||
migrator := migration.NewMigrator(db)
|
||||
```
|
||||
|
||||
#### 主要方法
|
||||
|
||||
| 方法 | 描述 | 示例 |
|
||||
|------|------|------|
|
||||
| `AddMigration(migration)` | 添加迁移 | `migrator.AddMigration(m)` |
|
||||
| `Up()` | 执行所有待处理迁移 | `migrator.Up()` |
|
||||
| `Down(steps)` | 回滚指定步数迁移 | `migrator.Down(2)` |
|
||||
| `Status()` | 显示迁移状态 | `migrator.Status()` |
|
||||
| `Reset()` | 重置数据库 | `migrator.Reset()` |
|
||||
| `Migrate(steps)` | 执行指定数量迁移 | `migrator.Migrate(3)` |
|
||||
|
||||
### Migration 结构
|
||||
|
||||
```go
|
||||
type Migration struct {
|
||||
Version string // 版本号 (YYYYMMDD_HHMMSS)
|
||||
Description string // 描述
|
||||
UpSQL string // 向前迁移 SQL
|
||||
DownSQL string // 回滚 SQL
|
||||
Timestamp time.Time // 时间戳
|
||||
}
|
||||
```
|
||||
|
||||
## 开发新迁移
|
||||
|
||||
### 1. 添加到 migrations.go
|
||||
|
||||
```go
|
||||
{
|
||||
Version: "20250111_120000",
|
||||
Description: "Add user avatar field",
|
||||
Timestamp: time.Date(2025, 1, 11, 12, 0, 0, 0, time.UTC),
|
||||
UpSQL: `
|
||||
ALTER TABLE user ADD COLUMN avatar VARCHAR(255) DEFAULT '';
|
||||
CREATE INDEX IF NOT EXISTS idx_user_avatar ON user(avatar);
|
||||
`,
|
||||
DownSQL: `
|
||||
DROP INDEX IF EXISTS idx_user_avatar;
|
||||
-- SQLite specific: recreate table without avatar field
|
||||
CREATE TABLE user_temp AS
|
||||
SELECT id, username, password, email, status, created_at, updated_at
|
||||
FROM user;
|
||||
DROP TABLE user;
|
||||
ALTER TABLE user_temp RENAME TO user;
|
||||
`,
|
||||
},
|
||||
```
|
||||
|
||||
### 2. 版本号规范
|
||||
|
||||
- 格式: `YYYYMMDD_HHMMSS`
|
||||
- 示例: `20250111_120000` (2025年1月11日 12:00:00)
|
||||
- 确保唯一性和时间顺序
|
||||
|
||||
### 3. SQL 编写规范
|
||||
|
||||
#### UP Migration (UpSQL)
|
||||
|
||||
```sql
|
||||
-- 使用 IF NOT EXISTS 确保幂等性
|
||||
CREATE TABLE IF NOT EXISTS new_table (...);
|
||||
ALTER TABLE user ADD COLUMN IF NOT EXISTS new_field VARCHAR(255);
|
||||
CREATE INDEX IF NOT EXISTS idx_name ON table(field);
|
||||
|
||||
-- 数据迁移使用 OR IGNORE
|
||||
INSERT OR IGNORE INTO table (field) VALUES ('value');
|
||||
UPDATE table SET field = 'value' WHERE condition;
|
||||
```
|
||||
|
||||
#### DOWN Migration (DownSQL)
|
||||
|
||||
```sql
|
||||
-- SQLite 不支持 DROP COLUMN，需要重建表
|
||||
CREATE TABLE table_temp (
|
||||
-- 列出所有保留的字段
|
||||
id INTEGER PRIMARY KEY,
|
||||
existing_field VARCHAR(255)
|
||||
);
|
||||
|
||||
INSERT INTO table_temp SELECT id, existing_field FROM table;
|
||||
DROP TABLE table;
|
||||
ALTER TABLE table_temp RENAME TO table;
|
||||
|
||||
-- 重建索引
|
||||
CREATE INDEX IF NOT EXISTS idx_name ON table(field);
|
||||
```
|
||||
|
||||
## SQLite 特殊考虑
|
||||
|
||||
### 不支持的操作
|
||||
|
||||
SQLite 不支持以下操作：
|
||||
- `ALTER TABLE DROP COLUMN`
|
||||
- `ALTER TABLE MODIFY COLUMN`
|
||||
- `ALTER TABLE ADD CONSTRAINT`
|
||||
|
||||
### 解决方案
|
||||
|
||||
使用表重建模式：
|
||||
|
||||
```sql
|
||||
-- 1. 创建新表结构
|
||||
CREATE TABLE table_new (
|
||||
id INTEGER PRIMARY KEY,
|
||||
field1 VARCHAR(255),
|
||||
-- 新字段或修改的字段
|
||||
field2 INTEGER DEFAULT 0
|
||||
);
|
||||
|
||||
-- 2. 复制数据
|
||||
INSERT INTO table_new (id, field1, field2)
|
||||
SELECT id, field1, COALESCE(old_field, 0) FROM table;
|
||||
|
||||
-- 3. 删除旧表
|
||||
DROP TABLE table;
|
||||
|
||||
-- 4. 重命名新表
|
||||
ALTER TABLE table_new RENAME TO table;
|
||||
|
||||
-- 5. 重建索引和触发器
|
||||
CREATE INDEX IF NOT EXISTS idx_field1 ON table(field1);
|
||||
```
|
||||
|
||||
## 测试
|
||||
|
||||
### 单元测试
|
||||
|
||||
```go
|
||||
func TestMigration(t *testing.T) {
|
||||
// 创建内存数据库
|
||||
db, err := gorm.Open(sqlite.Open(":memory:"), &gorm.Config{})
|
||||
require.NoError(t, err)
|
||||
|
||||
// 创建迁移器
|
||||
migrator := migration.NewMigrator(db)
|
||||
|
||||
// 添加测试迁移
|
||||
migrator.AddMigration(testMigration)
|
||||
|
||||
// 测试向前迁移
|
||||
err = migrator.Up()
|
||||
assert.NoError(t, err)
|
||||
|
||||
// 验证表结构
|
||||
assert.True(t, db.Migrator().HasTable("test_table"))
|
||||
|
||||
// 测试回滚
|
||||
err = migrator.Down(1)
|
||||
assert.NoError(t, err)
|
||||
|
||||
// 验证回滚结果
|
||||
assert.False(t, db.Migrator().HasTable("test_table"))
|
||||
}
|
||||
```
|
||||
|
||||
### 集成测试
|
||||
|
||||
```bash
|
||||
# 在测试数据库上运行迁移
|
||||
go run cmd/migrate/main.go -f etc/test.yaml -c up
|
||||
|
||||
# 验证数据完整性
|
||||
sqlite3 test.db "SELECT COUNT(*) FROM user;"
|
||||
|
||||
# 测试回滚
|
||||
go run cmd/migrate/main.go -f etc/test.yaml -c down -s 1
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 迁移设计
|
||||
|
||||
- **小步快跑**: 每次迁移只做一件事
|
||||
- **可回滚**: 确保每个迁移都可以安全回滚
|
||||
- **向后兼容**: 新字段使用默认值，避免破坏现有功能
|
||||
- **测试优先**: 在开发环境充分测试后再部署
|
||||
|
||||
### 2. 数据安全
|
||||
|
||||
```go
|
||||
// 在重要操作前备份
|
||||
migrator.CreateBackup()
|
||||
|
||||
// 使用事务
|
||||
tx := db.Begin()
|
||||
defer func() {
|
||||
if r := recover(); r != nil {
|
||||
tx.Rollback()
|
||||
}
|
||||
}()
|
||||
|
||||
// 执行迁移
|
||||
err := migrator.Up()
|
||||
if err != nil {
|
||||
tx.Rollback()
|
||||
return err
|
||||
}
|
||||
|
||||
tx.Commit()
|
||||
```
|
||||
|
||||
### 3. 性能优化
|
||||
|
||||
```sql
|
||||
-- 大表迁移时删除索引
|
||||
DROP INDEX idx_large_table_field;
|
||||
|
||||
-- 执行数据迁移
|
||||
UPDATE large_table SET new_field = 'value';
|
||||
|
||||
-- 重建索引
|
||||
CREATE INDEX idx_large_table_field ON large_table(field);
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### Q: 如何处理冲突的迁移版本？
|
||||
|
||||
A: 使用时间戳版本号，确保每个版本唯一。如果出现冲突，重新生成版本号。
|
||||
|
||||
### Q: SQLite 如何删除字段？
|
||||
|
||||
A: SQLite 不支持 DROP COLUMN，需要重建表。参考上面的表重建模式。
|
||||
|
||||
### Q: 如何在生产环境安全迁移？
|
||||
|
||||
A: 1) 备份数据库 2) 在测试环境验证 3) 使用预览模式检查 4) 执行迁移 5) 验证结果
|
||||
|
||||
### Q: 迁移失败如何恢复？
|
||||
|
||||
A: 1) 使用 Down 迁移回滚 2) 从备份恢复 3) 手动修复数据
