通过在输入框中输入标识号并按下按钮来执行 Oracle SQL 查询
Execute Oracle SQL query by input Identification number inside entry box and pressing button
我是 python 的新手。我尝试开发一个程序，它在数据库中执行一些 Oracle SQL 查询。所以接下来的概念是：我在这里有一个输入框，我输入一个个人 ID，然后我必须按下从输入框中收集输入的个人 ID 并将其注入到已经准备好的 SQL 查询中的按钮，然后查询将被执行和 select 有关个人 ID 所有者的数据。现在我卡住了，我无法从输入框中收集数据。请帮忙。非常感谢。
