当我按回车键时，有'＆gt;的输出没有其他反应，怎么了？

Answer 1

你的问题在最后一行。列名不能包含&或'：

-> Total_liabilities_&_shareholder's_equity VARCHAR(20));

将其更改为：

-> Total_liabilities_shareholders_equity VARCHAR(20));

修改

事实证明MySQL确实支持列名中的特殊字符，但你必须将它们转义：

-> `Total_liabilities_&_shareholder's_equity` VARCHAR(20));

出于可读性原因，我强烈建议不要这样做。

来自docs：


可以引用标识符或   不带引号的。如果标识符包含   特殊字符或是保留的   一句话，你必须随时引用它   参考它。一组字母数字   当前角色的字符   设置，“_”和“$”并不特殊。

标识符引号字符是反引号（“`”）。

Answer 2

在字段名称中仅使用字母数字字符。没有＆amp;和'人物

Answer 3

SO代码突出显示是一个提示。你的一个字段名中有一个撇号，MySQL正在将其解释为永远不会终止的字符串文字的开头。它耐心等待你完成你的字符串。

MySQL语法：无法创建表
