为什么我无法将 SQL Server 连接到我的节点 js

Question

我正在使用“mssql”npm 包将我的 SQL 服务器连接到我的节点 JS。 我经历了几个问题，但没有在任何地方解决。

我的 SQL Server 登录凭据是-

server type : Database Engine
Server name : DESKTOP-MPF88ST\KUSHAL 
authentication : sql server authentication 
login : username 
password : password

我想要的数据库是schoolDB ，我的代码是这样的

const sql =require("mssql")

const config = {
        login: 'username',
        password:'password',
        server: 'localhost',
        database: "schoolDB",
        options : {
            enableArithAbort: true
        },
        port : 1433
}

sql.connect(config, (err) => {
        if(err){
            console.log(err);
        }
        else {
            console.log("Connected")
        }

我启用并设置了 TCP/IP，启用了 SQL Server 浏览器，但它仍然抛出错误 -

ConnectionError: Failed to connect to localhost:1433 - Could not connect (sequence)

  }
}

我该如何解决？

Answer 1

尝试这个：

const sql = require('mssql/msnodesqlv8')

const pool = new sql.ConnectionPool({
  login: 'username',
  password:'password',
  database: 'schoolDB',
  server: 'DESKTOP-MPF88ST\KUSHAL',
  driver: 'msnodesqlv8',
  options: {
    trustedConnection: true
  }
})

pool.connect().then(() => {
  //sample query
  pool.request().query('select 1 as number', (err, result) => {
        console.dir(result)
    })
})

确保 TCP/IP 协议已启用，因为默认情况下它是禁用的。

脚步：

1. 进入计算机管理

2. 在服务和应用程序-> SQL Server 配置管理器-> SQL Server 网络配置-> 单击“MSSQLSERVER 的协议”

3. 您将看到 TCP/IP 部分（启用右键单击并启用它）
