Question

首次使用MySQL（在node/react应用程序中），并且在尝试向表中插入一些值时遇到错误。我收到的特定错误消息是：

错误：ER_BAD_FIELD_ERROR：“字段列表”中的未知列“名称”

这是我的桌子：

const table =
    "CREATE TABLE IF NOT EXISTS 
     posts(id int AUTO_INCREMENT, 
           name VARCHAR(30), 
           email VARCHAR(50), 
           content VARCHAR(500), 
           stamp VARCHAR(40), 
           PRIMARY KEY(id))";

这是查询：

 //  Insert post 1
app.get("/addpost1", (req, res) => {
  let post = {
    name: "Joe Blogs",
    email: "jblogs@gmail.com",
    content:
      "Interesting post Phil. It's great to see that a blog really can come alive when the comments update in real-time. The commenting system becomes a conversation platform.",
    stamp: "July 30 2019"
  };
  let sql = "INSERT INTO posts SET ?";
  let query = db.query(sql, post, (err, result) => {
    if (err) throw err;
    console.log(result);
    res.send("Post 1 added...");
  });
});

与此有关，我一直遇到错误。任何帮助表示赞赏。

这是正确的语法：

INSERT INTO `table`(`column1`, `column2`) VALUES ([value-1],[value-2])

所以在您的代码中就像：

INSERT INTO `posts` (`name`, `email`, `content`) VALUES ([name:], [email:], [content:])

MYSQL：BAD_FIELD_ERROR“字段列表”中的未知列
