【问题描述】：

我的 jquery 代码有问题。我是 jquery 新手，所以我不确定问题出在哪里。

【问题讨论】：

您在此处粘贴了一堆代码，但没有尝试向我们解释问题可能出在哪里/是什么。

这和jQuery有什么关系？那是一个 javascript 库，它与 mysql 或数据库无关。

如果您在尝试加载使用mysqldump 创建的文件时遇到错误，通常是因为您尝试加载的 MySQL 版本与创建它的版本不兼容。

【参考方案1】：

这样的行是问题所在：

INSERT INTO `Training Academy` (Training Academyid, Training Academyname, Training Academycountry) VALUES ('1111111','Beacon','Vale'),('2222222','Haven','Mistral'),('3333333','Shade','Vacuo');

您的列名中包含空格，您需要在它们周围加上反引号。

INSERT INTO `Training Academy` (`Training Academyid`, `Training Academyname`, `Training Academycountry`) VALUES ('1111111','Beacon','Vale'),('2222222','Haven','Mistral'),('3333333','Shade','Vacuo');

您在插入Head Master、Villain Team 和Hunter Team 时遇到同样的问题。

欲了解更多信息，请参阅When to use single quotes, double quotes, and backticks in MySQL

如果这是使用来自phpMiniAdmin 的数据库导出命令创建的，我建议你把它扔掉——这是一个不可原谅的错误。 phpMyAdmin 更受欢迎，而且错误可能更少。

【参考方案2】：

我在这里发现了 3 个问题。

缺少列名的反引号。 外键缺少默认值，因此如果未提供，则在插入过程中失败 您已经互换了列，因此该行将失败。

INSERT INTO `Hunter Team` (`Hunter Teamname`, `Hunter Teamid`) VALUES (51515,'RWBY'), (78787,'JNPR'), (47155,'STRQ');

这是您的完整工作脚本。
