我试图删除数据库并创建一个新数据库，但仍然显示错误。

可能是什么问题？请建议。

谢谢，

【问题讨论】：

  • 什么是utf编码类型？
  • 我怎么知道？
  • 您仅向我们提供了错误日志。理想情况下，还应向我们提供您的数据库结构和足以重现问题的代码。
  • 也许值得一提的是 MySQL 的 utf8 字符集实际上并不支持所有的 Unicode。 For all of Unicode, you need utf8mb4.

标签： mysql angularjs node.js unicode


【解决方案1】：

试试这个

ALTER DATABASE databasename CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

【讨论】：

  • 或许值得一提的是 MySQL 的 utf8 字符集实际上并不支持所有的 Unicode。对于所有 Unicode，您需要 utf8mb4。
  • 你是怎么知道的？工作出色。谢谢！
  • （高棉语在 utf8 和 utf8mb4 中都可用。）
