### 1.5 DM 达梦
TODO 暂未支持
下载达梦docker镜像 https://download.dameng.com/eco/dm8/dm8_20230808_rev197096_x86_rh6_64_single.tar
## 2. MySQL 转换其它数据库
加载镜像文件在镜像tar文件所在目录运行
```Bash
docker load -i dm8_20230808_rev197096_x86_rh6_64_single.tar
````
在项目`sql/tools`目录下运行:
```Bash
docker compose up -d dm8
# 注意:启动完 sqlserver 后,需要手动再执行如下命令,因为 SQL Server 不支持初始化脚本
docker compose exec dm8 bash -c "exec /opt/dmdbms/bin/disql SYSDBA/SYSDBA001 \`/tmp/schema.sql"
exit
```
**注意**: `sql/dm/ruoyi-vue-pro-dm8.sql`文件编码必须为`GBK`或者`GBK`超集
暂不支持 MacBook Apple Silicon因为 达梦 官方没有提供 Apple Silicon 版本的 Docker 镜像。
## 2. 测试数据库docker容器的销毁重建
开发测试过程中有时候需要创建全新干净的数据库。由于测试数据docker容器采用数据卷volume挂载数据库实例的数据目录因此销毁数据需要停止容器后删除数据卷然后再重新创建容器。以postgres为例操作如下
```Bash
docker compose down postgres
docker volume rm ruoyi-vue-pro_postgres
```
## 3. MySQL 转换其它数据库
### 2.1 实现原理
