一下子运行 七八十个  select 将会是什么样的体验呢？

业务部门提供了一个需要，要求从爬虫数据中提取出88家的数据，

并且也提供了一个excel表格，如下图：

这个时候我们可以通过拍卖行，拍卖时间，拍卖会专场写SQL语句，单个SQL是这样写的。其中数据库表格的数据是540万，我们在建表的时候已经为 item_auct_time ，session_name

，aucr_name_spider ，添加了索引。所以SQL的执行速度很快。

SELECT * FROM `guonei_artron_items_core__qingxi` WHERE item_auct_time = "" AND aucr_name_spider ="中国嘉德国际拍卖有限公司" 
and session_name ="大观——四海崇誉庆典之夜·古代"

但是面对的是 88 行，我们总不能写88 个SQL语句吧，这样效率太低了，

这个时候我们可以用代码直接生成SQL语句

首先去复制这三行的数据，然后封装一个列表。如下
