这不是有效的SQL语法。您不能将占位符用于这样的一组值，必须将它们单独分开：

connection.query(
  "INSERT INTO details (name, pwd) VALUES (?,?)",
  [ "Name", "Pwd" ]
);

将所有这些条件作为一个占位符提供会将它们封装在字符串中，这会破坏语法

重要信息：始终对密码进行哈希运算，切勿使用纯文本存储密码。至少它是专门为密码设计的，而不是像SHA1这样的高速散列或像MD5这样的折衷散列

如果你使用节点，你可能想至少考虑使用它可以为你做很多繁重的事情，并且很好地与其他节点组件一起玩。

什么，确切地说，是<代码> Req.Boo< <代码>的内容？而

SHOW CREATE TABLE details

的MySQL输出是什么？
