node.js连sqlserver demo

node.js连sqlserver demo

无需多言，直接上代码，因为本例只是简单的测试连接sqlserver(sql 2008 r2),并执行select

1 首先在package.json中添加依赖 

"dependencies": {
        "koa": "2.0.0",
        "koa-bodyparser": "3.2.0",
        "koa-router": "7.0.0",
        "mssql": "4.0.4",  
        "mysql": "2.11.1",
        "sequelize": "3.24.1",
        "mocha": "3.0.2",
        "mz": "2.4.0",
        "supertest": "3.0.0",
        "ws": "1.1.1"
    }

"mssql": "4.0.4", 这行，其它是用于其它作用的，不用管

2 添加 msdb.js

/**
 * Created by jack on 2017/8/26.
 */
var sqlserver = require('mssql');

var msdb = {};
var dbConfig = {
    server: "127.0.0.1",
    database: "test",
    user: "sa",
    password: "123456",
    port: 1433
};



var db = function(strsql){
    
    sqlserver.connect(dbConfig).then(function () {
        var req = new sqlserver.Request().query(strsql).then(function (recordset) {
            console.log(recordset);
        })
            .catch(function (err) {
                console.log(err);
            });
    })
        .catch(function (err) {
            console.log(err);
        });
};


module.exports = db;

3 添加 msdbtest.js

/**
 * Created by jack on 2017/8/26.
 */
var db = require('./msdb.js');
var sql="select top 10 * from t_city;"
db(sql,function(err,result){
    if (err) {
        console.log(err);
        return;
    }
    console.log(result);
});

4 运行测试 

在命令行运行 node msdbtest.js 可以看到输出结果
