首先下載微軟的mssql支援庫：npm install -g [email protected]

var mssql = require("mssql");
var user = "sa",
    password = "masterkey",
 server = "127.0.0.1",
 database = "EMacIntf";
 
 var db={};
 
var config = {
 user: user,
 password: password,
 server: server,
 database: database,
 options:{
  //encrypt: true
 },
 pool:{
  min: 0,
  idleTimeoutMillis: 3000
 }
};var restoreDefaults = function(){
 config={
  user:user,
  password:password,
  server:server,
  database:database,
  options:{
   //encrypt: true
  },
  pool:{
   min: 0,
   idleTimeoutMillis: 3000
  }
 };
}db.querySql = function(sql, params, callBack){
 var connection = new mssql.Connection(config, function(err){
  var ps = new mssql.PreparedStatement(connection);
  if(params != ""){
   for(var index in params){
    if(typeof params[index] == "number"){
     ps.input(index, mssql.Int);
    }else if(typeof params[index] == "string"){
     ps.input(index, mssql.NVarChar);
    }
   }
  }
  ps.prepare(sql, function(err){
   if(err)
    console.log(err);
   ps.execute(params, function(err, recordset){
    callBack(err, recordset);
    ps.unprepare(function(err){
     if(err)
      console.log(err);
    });
   });
  });
 });
 restoreDefaults();
};module.exports=db;這裡執行查詢語句、增刪改、儲存過程語句都可以，基本上可以完成正常的業務邏輯操作。呼叫範例：var db = require("./db.js");db.querySql("select * from XXX", null, function(err, data){
         res.send(JSON.stringify(data));
    });
