Question

我编写了这段代码，但是当我在mysql中尝试使用存储过程时，我不知道为什么这段代码与mysql db有错误：

var mysql = require("mysql");

var con = mysql.createConnection({
    host: "localhost",
    port: "8889",
    user: "root",
    password: "root",
    database: "ResetAccountTest"
});

con.connect(function(err){
    if(err){
       console.log('Error connecting to Database');
       return;
    } console.log('Connection established');
});

var accountTest = { email: 'mra@fpt.edu.vn', password: 'root', bit: '1' };
con.query('call newAccount(?, ?, ?)', accountTest, function(err, result) {
    if (err) throw err;

    console.log(result.insertId);
});

con.end(function(err) {
// The connection is terminated gracefully
// Ensures all previously enqueued queries are still
// before sending a COM_QUIT packet to the MySQL server.
});

这是错误：

对不起，伙计们，我是nodejs的初学者。我希望社区能帮助我解决这个问题：D

我通过更改第20行解决了这个问题：var sql = con.query（'call newAccount（？，？，？）'，[accountTest.email，accountTest.password，accountTest.bit]，function（err），result）{if（err）throw err; console.log（result.insertId）;}）;

var mysql = require("mysql");

var con = mysql.createConnection({
    host: "localhost",
    port: "8889",
    user: "root",
    password: "root",
    database: "ResetAccountTest"
});

con.connect(function(err){
    if(err){
       console.log('Error connecting to Database');
       return;
    } console.log('Connection established');
});

var sql = con.query('call newAccount(?, ?, ?)', [accountTest.email, accountTest.password, accountTest.bit], function(err, result) { 
      if (err) throw err; 
      console.log(result.insertId); 
});

con.end(function(err) {
// The connection is terminated gracefully
// Ensures all previously enqueued queries are still
// before sending a COM_QUIT packet to the MySQL server.
});

（Mysql）使用存储过程和nodejs插入数据？
