这是我的连接设置方式:
Connection conn = DriverManager.getConnection(url + dbName + "?useUnicode=true&characterEncoding=utf-8", userName, password);

当tyring为表添加一行时,我收到以下错误:
Incorrect string value: '\xF0\x90\x8D\x83\xF0\x90...' for column 'content' at row 1

我正在插入数千条记录,当文本包含\ xF0时,我总是会收到此错误(即错误的字符串值始终以\ xF0开头).

该列的排序规则为utf8_general_ci.

可能是什么问题呢？

我在mysql中有一个简单的数据库,我尝试打印结果,但编码是错误的.它发生在orm模型和纯sql模式下.

使用相同的sqlalchemy conf,纯粹的使用工作和烧瓶应用程序不.我也试过在PHP中进行简单测试,它运行正常.

我究竟做错了什么？
