【问题描述】：

我在尝试将数据帧推送到 sql 时遇到一个奇怪的 SQL 错误。我的df 只是一个我试图推送到我的 SQL 数据库的 pandas 数据框。我以前从未遇到过问题，并且错误消息对于问题所在的信息非常无用。错误类似于：mysql - Operand should contain 1 column(s) 虽然我用的是python。

我的df 中的.head() 看起来像这样，要推送的代码和我的错误看起来像这样：

(Background on this error at: http://sqlalche.me/e/14/e3q8)

这没有意义，因为我有 23 列？数据库也包含这些带有这些标题的确切列，所以我不明白为什么不推送。

我是 mySQL 的新手，很高兴提供任何可能有助于解决问题的数据或结构。

任何问题的迹象都会非常有帮助。谢谢

【问题讨论】：

您确定news 是表还是视图？

@BarbarosÖzhan 是的。我什至放弃了它，让它创建一个新的，但它仍然失败。

数据框中是否有任何列是列表、字典、json 等？

@eduardoftdo 列本身只是字符串，尽管我确实有包含列表的列值。

minimal reproducible example 甚至是数据库结构以及您在数据框中加载和更改的内容都可以帮助我们理解问题。

【参考方案1】：

当我尝试将包含列表的列推送到不兼容的 SQL 数据库中时出现此错误。为了解决这个问题，我只是将列表转换为字符串，它就可以工作了。

不确定这是否会有所帮助，但这是我解决此特定问题的方法。
