单元格中的文本有“,”上传 .csv 不起作用

Question

我用来上传数据的 .csv 文件的单元格中有“，”。我如何忽略单元格中的“，”，以便该单元格中的数据进入数据库的单个字段。

cell data="墙壁上有铅基油漆剥落，墙壁上长出霉菌。总结与铅和霉菌相关的健康危害，并描述可以采取哪些措施来控制这两个公共卫生问题。请务必用文献中的证据支持你的立场”

该文本应该出现在一个字段中，但由于文本中有一个“，”，所以它出现在 2 个字段中。

有谁知道解决这个问题。

感谢

如果您使用 LOAD DATA INFILE 语法，请将 ENCLOSED BY '"' 添加到您的查询中。
