SQL Server与节点js的连接

Question

我正在尝试在nodejs项目和运行Microsoft SQL Server 2005的服务器之间建立连接.我正在使用节点模块mssql,但是当我尝试创建连接时出现这些错误:

{[ConnectionError:无法连接到15000ms中的123.123.12.1:1433]
名称:'ConnectionError',
消息:'无法连接到15000ms中的123.123.12.1:1433',
代码:'ETIMEOUT'}

我的联系是由

var sql = require('mssql');

var dbConfig = {
    server:'123.123.12.1',
    database:'testingDB',
    user:'userName',
    password:'pass',
    port:1433
};

function getEmp() {
    var conn = new sql.Connection(dbConfig);
    var req = new sql.Request(conn);

    conn.connect(function(err) {
        if(err) {
            console.log(err);
            return;
        }
    else {
        console.log('success');
    }
});
}

getEmp();

我不确定我做错了什么,如果有帮助我使用的是云端9 IDE.

Answer 1

把你的var req = new sql.Request(conn)内部连接.

// config for your database
var config = {
    user: 'sa',
    password: 'mypassword',
    server: 'localhost', 
    database: 'SchoolDB' 
};

// connect to your database
sql.connect(config, function (err) {

    if (err) console.log(err);

    // create Request object
    var request = new sql.Request();

    // query to the database and get the records
    request.query('select * from Student', function (err, recordset) {

        if (err) console.log(err)

        // send records as a response
        res.send(recordset);

    });
});

Answer 2

它对我有用.首先通过npm安装mssql(npm install --save mssql)

var sql = require('mssql');

用于本地sql server

var sqlConfig = {
  user: 'sa',
  password: 'admin',
  server: 'CBMOBILESHAMIM\\SQLEXPRESS',  
  database: 'databaseName'
};

对于天蓝色的服务器

var sqlConfig = {
  user: 'adminLogin',
  password: 'admin',
  server: 'severname.database.windows.net',    // don't add tcp & port number
  database: 'databaseName',
  options: {
    encrypt: true
  }
};

现在连接到服务器

(async function () {
  try {
    console.log("sql connecting......")
    let pool = await sql.connect(sqlConfig)
    let result = await pool.request()
      .query('select * from Subject')  // subject is my database table name

    console.log(result )

  } catch (err) {
    console.log(err);
  }
})()
