python定时查询starrocks将结果保存在excel

背景

在工作过程中要定期的更新excel表的信息，每个星期都要去查询strarocks的数据导出结果到excel，俗话说：“不会偷懒的运维不是好运维”，于是写了python小程序解决这个重复的工作，设置定时任务，直接去服务器下载导出的excel表格即可。

代码

代码的逻辑简单介绍：将要执行的SQL以名称进行区分保存并放到目录：SQLfileDir，设置结果存放路径：./…/outputdir/。python先查询数据，然后以SQL文件名前缀为excle名称保存，最后移动到指定目录。

MySQL的导出也可以用该脚本，因为starrocks/Doris连接都是用的MySQL驱动，兼容MySQL语法。
