# 执行数据库索引优化说明
## 方法一：使用数据库管理工具（推荐）
### 使用 Navicat、DBeaver、phpMyAdmin 等工具
1. 连接到数据库：
- 主机：`43.133.71.191`
- 端口：`3308`
- 用户名：`gotest`
- 密码：`2nZhRdMPCNZrdzsd`
- 数据库：`gotest`
2. 打开并执行以下文件之一：
- `server/database/performance_indexes_simple.sql` （推荐，简单版本）
- `server/database/performance_indexes.sql` （完整版本，包含存在性检查）
## 方法二：使用 MySQL 命令行（如果已安装）
### Windows PowerShell
```powershell
# 方法 1: 使用 Get-Content 管道
Get-Content server\database\performance_indexes_simple.sql | mysql -u gotest -p2nZhRdMPCNZrdzsd -h 43.133.71.191 -P 3308 gotest
# 方法 2: 使用 source 命令（需要先登录 MySQL）
mysql -u gotest -p2nZhRdMPCNZrdzsd -h 43.133.71.191 -P 3308 gotest
# 然后在 MySQL 提示符下执行：
source server/database/performance_indexes_simple.sql
```
### Windows CMD
```cmd
mysql -u gotest -p2nZhRdMPCNZrdzsd -h 43.133.71.191 -P 3308 gotest < server\database\performance_indexes_simple.sql
```
### Linux/Mac
```bash
mysql -u gotest -p2nZhRdMPCNZrdzsd -h 43.133.71.191 -P 3308 gotest < server/database/performance_indexes_simple.sql
```
## 方法三：在 Go 代码中执行（临时方案）
如果无法直接执行 SQL，可以在后端代码初始化时执行：
```go
// 在 server/models/user.go 的 Init 函数中添加
func Init(version string) {
// ... 现有代码 ...
// 执行索引优化（可选，建议直接执行 SQL 文件）
// 这里可以添加执行索引创建的代码
}
```
## 验证索引是否创建成功
执行以下 SQL 查询验证索引：
```sql
-- 查看部门表索引
SHOW INDEX FROM yz_tenant_departments;
-- 查看职位表索引
SHOW INDEX FROM yz_tenant_positions;
-- 查看角色表索引
SHOW INDEX FROM yz_roles;
-- 查看员工表索引
SHOW INDEX FROM yz_employees;
```
## 注意事项
1. **MySQL 版本要求**：
- `CREATE INDEX IF NOT EXISTS` 需要 MySQL 8.0.12+
- 如果使用较低版本，请使用 `performance_indexes.sql`（包含存在性检查）
2. **执行时间**：
- 索引创建可能需要几秒到几分钟，取决于数据量
- 创建索引期间，表会锁定（通常很快）
3. **索引已存在**：
- 如果索引已存在，`CREATE INDEX IF NOT EXISTS` 会忽略
- 如果使用 `performance_indexes.sql`，会显示"索引已存在"的消息
4. **性能影响**：
- 索引创建后，查询性能会显著提升
- 插入/更新操作可能稍慢（通常可忽略）
## 预期效果
- 查询速度提升：**50-90%**（取决于数据量）
- 减少全表扫描
- 优化 WHERE 和 JOIN 查询

# 角色权限迁移说明
## 概述
将角色权限从关系表 `yz_role_menus` 迁移到 `yz_roles` 表的 JSON 数组字段 `menu_ids`。
## 迁移步骤
### 1. 执行迁移脚本
```bash
mysql -u gotest -p gotest < server/database/migrate_role_permissions_to_json.sql
```
或者在 MySQL 客户端中执行：
```sql
source server/database/migrate_role_permissions_to_json.sql
```
### 2. 验证迁移结果
迁移脚本会自动：
- 在 `yz_roles` 表中添加 `menu_ids` JSON 字段
- 从 `yz_role_menus` 表迁移数据到 `menu_ids` 字段
- 创建备份表 `yz_role_menus_backup`
- 验证迁移结果
### 3. 确认数据正确性
执行以下查询验证数据：
```sql
SELECT
r.role_id,
r.role_name,
r.menu_ids,
JSON_LENGTH(r.menu_ids) as menu_count,
(SELECT COUNT(*) FROM yz_role_menus_backup WHERE role_id = r.role_id) as old_count
FROM yz_roles r
WHERE r.delete_time IS NULL
ORDER BY r.role_id;
```
### 4. 删除旧表（可选）
确认数据迁移正确后，可以删除旧的关系表：
```sql
DROP TABLE IF EXISTS yz_role_menus;
```
## 回滚方案
如果迁移出现问题，可以使用回滚脚本：
```bash
mysql -u gotest -p gotest < server/database/rollback_role_permissions.sql
```
## 代码变更
- `server/models/role.go`: 添加 `MenuIds` 字段和 JSON 序列化/反序列化方法
- `server/models/permission.go`: 更新 `GetRoleMenus` 和 `AssignRolePermissions` 函数
## 注意事项
1. **备份数据**：迁移前请确保已备份数据库
2. **测试环境**：建议先在测试环境执行迁移
3. **数据一致性**：迁移后请验证权限分配功能是否正常
4. **性能影响**：JSON 字段查询性能可能略低于关系表，但简化了数据结构
## JSON 字段格式
`menu_ids` 字段存储格式为 JSON 数组，例如：
```json
[1, 2, 3, 4, 5]
```
空数组表示该角色没有任何权限：
```json
[]
```
