Python代码生成错误`ORA-00917:缺少逗号'；，但是没有逗号丢失。怎么了？

我编写了Python代码，但出现以下错误：

错误ORA-00917:缺少逗号

但是没有遗漏逗号；怎么了

我不知道您的错误位置，它可能是由几个原因造成的，例如，如果您的字符串未包含在

“

引号中。将变量传递给sql是一种非常错误的方法

就绑定变量的使用（oracle SQL最佳实践的基石）而言，最好是将您的语句编写为（未测试）：

调试此类问题的最简单方法是打印出该语句并在您常用的任何SQL工具中进行测试。在这里，你基本上要求我们找出你的一个拼写错误…你必须阅读关于ORA的内容-这意味着错误来自Oracle，而不是Python。也就是说，您应该真正学习一些Python，因为这是一种构建SQL字符串的非常糟糕的方法。（提示：三重引号和

，'.join（）
