无法更新MySql中的数据（错误：ER_PARSE_ERROR）

Question

我正在尝试创建“编辑个人资料”页面，以便用户可以编辑他/她的个人资料信息。但我在某个地方搞砸了，它不起作用。我假设我在查询部分犯了一个错误。

我的控制器（API）：

export const editUser = (req, res) => {
  const q = "SELECT * FROM users WHERE id = ?";
  const userId = req.params.userId;

  db.query(q, [userId], (err, data) => {
    if (err) return res.status(409).json(err);

    const q = "UPDATE users SET (`name`, `surname`, `headline`) VALUES (?)";
    const values = [req.body.name, req.body.surname, req.body.headline];

    db.query(q, [values], (err, data) => {
      if (err) return res.status(500).json(err);
      return res.status(200).json("User has been updated.");
    });
  });
};

我的路线（API）：

const router = express.Router();
router.post("/edit-profile/:userId", editUser);

export default router

我的客户站点代码：

  const [err, setErr] = useState(null);
  const [inputs, setInputs] = useState({ name: "", surname: "", headline: "" });

  const handleChange = (e) => {
    setInputs((prev) => ({ ...prev, [e.target.name]: e.target.value }));
    console.log(inputs);
  };

  const handleClick = async (e) => {
    e.preventDefault();

    try {
      await axios.post("http://localhost:8800/api/users/edit-profile/" + userId, inputs);
    } catch (err) {
      setErr(err.response.data);
    }
  };

HTML：

          <form action="a">
            <div>
              <p>Name:</p>
              <input
                type="text"
                placeholder={error ? "Something Went wrong" : isLoading ? "Loading" : data.name}
                name="name"
                onChange={handleChange}
              />
            </div>
            <div>
              <p>Surname:</p>
              <input
                type="text"
                placeholder={error ? "Something Went wrong" : isLoading ? "Loading" : data.surname}
                name="surename"
                onChange={handleChange}
              />
            </div>
            <div>
              <p>Headline:</p>
              <input
                type="text"
                placeholder={error ? "Something Went wrong" : isLoading ? "Loading" : data.headline}
                name="headline"
                onChange={handleChange}
              />
            </div>
          </form>

为了更简单，我尝试在 Insomnia 中发帖：

{
    "name": "asd",
    "surname": "asd", 
    "headline": "asd"
}
 

但我收到错误：

{
    "code": "ER_PARSE_ERROR",
    "errno": 1064,
    "sqlMessage": "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(`name`, `surname`, `headline`) VALUES ('asd', 'asd', 'asd')' at line 1",
    "sqlState": "42000",
    "index": 0,
    "sql": "UPDATE users SET (`name`, `surname`, `headline`) VALUES ('asd', 'asd', 'asd')"
}

我想编辑用户的用户名、姓氏和标题。

Answer 1

update

语句没有

values

子句，而是一系列

column=value

部分。您还缺少一个

where

子句，仅更新您获得 ID 的用户：

const q = 
    "UPDATE users SET `name` = ?, `surname` = ?, `headline` = ? WHERE `id` = ?";
const values = [req.body.name, req.body.surname, req.body.headline, userId];
