    '>
    '> 

当我按下回车时，有'>的输出，没有其他 react ，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));

编辑

事实证明，MySQL 确实支持列名中的特殊字符，但您必须对它们进行转义:

-> `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 :

An identifier may be quoted or unquoted. If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. The set of alphanumeric characters from the current character set, “_”, and “$” are not special.

The identifier quote character is the backtick (“`”).
