以下是一个使用 JDBC 的 MySQL 数据库操作实例:

1. 连接数据源

``` connection localhost localhost; conn server localhost hostname = "example.com" /proxy_pass;

2. 查询数据库

``` db = mysql.connect(hostname, connection); ```

3. 添加数据

``` connection localhost localhost = "example.com" /proxy_pass; `/ ```

4. 删除数据

db = mysql.drop(connection, "example.com", "example.com"); ```

5. 刷新数据库

``` connection localhost localhost = "example.com" /proxy_pass; `/ ```

6. 关闭数据库

``` connection localhost localhost = "example.com" /proxy_pass; `/ ```

7. 查看结果

``` db = mysql.show(); ```

8. 释放资源

``` db = mysql.release();

```
