如何使用 Node JS 将 SQL 查询从 \'.sql\' 文件执行到 MySQL 数据库中答案

【问题标题】：How to excute SQL Queries from '.sql' file into MySQL database using NodeJS如何使用 Node JS 将 SQL 查询从 \'.sql\' 文件执行到 MySQL 数据库中
【发布时间】：2022-08-19 17:25:15
【问题描述】：

堆栈和环境

我将NodeJS 用于后端服务器，MySQL 用于存储数据库。
我正在使用MySQL Workbench 来设计数据库模型。
使用 MySQL Workbench，我可以生成一个 \'.sql\' 脚本，其中包含我的数据库模型的所有查询。

如何使用 NodeJS 服务器将生成的 \'.sql\' 脚本执行到 MySQL 数据库中？

我已经按照这个在线教程Running SQL Queries from a ‘.sql’ file in NodeJS (SQLite) 尝试使用SQLite package，但不幸的是没有运气，它一直抛出错误。

非常感谢任何建议，感谢您的帮助:)

【解决方案1】：

您可以从文件中读取并对其执行查询：

const generatedScript = fs.readFileSync(path.join(__dirname, '../generated-script.sql')).toString();
const query = await db.query(generatedScript,  (err, result) => {
    if (err){
         throw err;
    }else{
        res.send("Query run successfully");
    }

db 配置文件可能如下所示：

const db = mysql.createConnection({
    host:"-your host here -",
    user:"-your user here-",
    password:"-your password here-",
    database:"-your database here-"
});
