mysql - 尝试npm运行迁移以部署我的应用程序时在heroku上出错

Question

我正在尝试在Heroku上部署我的应用，当我在heroku run bash上运行npm migration时遇到类型错误。
终端上的错误说这是SQL错字错误，但我看不到错误是什么。我尝试过更改引号，但也不起作用。任何帮助都将受到欢迎。
错误:

require("dotenv").config();
const mysql = require("mysql");

const DB_HOST = process.env.DB_HOST;
const DB_USER = process.env.DB_USER;
const DB_PASS = process.env.DB_PASS;
const DB_NAME = process.env.DB_NAME;

const con = mysql.createConnection({
  host: DB_HOST || "127.0.0.1",
  user: DB_USER || "root",
  password: DB_PASS || "root",
  database: DB_NAME || "5aday",
  multipleStatements: true
 
});

con.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");

您没有将sql语句分配给任何变量。第一个语句分配给sql变量，但后面的语句则不分配。 Year在第一个create table之后终止语句。
