SQL Server与节点js的连接 [英] SQL Server connection to node js

问题描述

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 ，但是在尝试创建连接时出现以下错误:

I am trying to establish a connection between nodejs project and server running Microsoft SQL Server 2005. I am using a node module mssql, but I get these errors when I am attempting to create a connection:

{[ConnectionError:在15000毫秒内无法连接到123.123.12.1:1433]
名称:"ConnectionError"，
消息:未能在15000毫秒内连接到123.123.12.1:1433"，
代码:"ETIMEOUT"}

{ [ConnectionError: Failed to connect to 123.123.12.1:1433 in 15000ms]
name: 'ConnectionError',
message: 'Failed to connect to 123.123.12.1:1433 in 15000ms',
code: 'ETIMEOUT' }

我的连接是

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();

我不确定自己在做什么错，如果有帮助，我正在使用cloud 9 IDE.

I am not sure what I am doing wrong, I am using a cloud 9 IDE if that helps.

推荐答案

将您的 var req =新sql.Request(conn)置于连接内部.

// 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);

    });
});
