通过存储过程插入记录不起作用（使用乏味的MS SQL驱动程序）

Question

I am working on an app. which has to insert records at an avg. rate of ~900 records/sec.
For this I am trying to build a console app based off TCP which listens for clients connecting to the server using Node.JS as my platform.

I am firing a stored procedure to insert static text (in table) as a parameter to the SP but its not working and no error(s) are caught.

Can anyone pls help me out with this? am new to node.js

My server side app:

var net     = require('net');
var fs      = require('fs');
var Connection = require('tedious').Connection;
var Request = require('tedious').Request;

var HOST = '127.0.0.1';
var PORT = 7000;
var timeout = 420000; // msec - *420000 

//db conn config
var config = {
  server: '192.168.0.57',
  userName: 'sa',
  password: 'sa',
  options: {
    database: "NodeJSBenchmark",
  }
 };
var lg = function(message) {
    console.log(message);
};

var server = net.createServer();
var connection = new Connection(config);

server.on('listening', function() {
    lg('Server listening on ' + HOST +':'+ PORT);
});

server.on('connection', function(sock) {
    sock.setTimeout(timeout, function() {
        try {
            sock.end();
        }
        catch(x) {
            lg('on end' + x);
        }
    });

    function executeStatement() {
    //var storedProcName = '[NodeJSBenchmark].[dbo].[spINSERTsockdata]';
    var storedProcName = 'spINSERTsockdata';
    var request = new Request(storedProcName, function(err, rowCount) {
    if(err){
      lg('Error on insert' + err);
    }
    else {
      lg(rowCount + ' rows2');
      lg('SP fininshed running..');
  }
    connection.close();
  });

  request.addParameter('sockdata', TYPES.VarChar, 'ping'); 

  request.on('doneProc', function(rowCount, more, returnStatus) {
    lg('Rows Changed: ' + rowCount + 'Return Stat: ' + returnStatus);  
  });

  connection.callProcedure(request);
  }

    sock.setNoDelay(true);

    //sock.setEncoding('ascii');

    // Identify incoming client
    sock.name = sock.remoteAddress + ":" + sock.remotePort 

    sock.on('data', function(data) {
        try {
        //lg("CONNECTED: "+sock.name);
        //lg("INCOMING DATA: "+data);
        sock.write(data);

        connection.on('connect', function(err) {
        // If conn is active; hit db..
        executeStatement();
        });

        }
        catch(x) {
            lg(x);
        }
    });

    sock.on('end', function(data) {
        try {
            sock.end();
        }
        catch(x) {
            lg('on end' + x);
        }
    });

    sock.on('error', function(err) {
        lg(err);
    });

    sock.on('close', function(data) {

        try {
            sock.end();
        }
        catch(x) {
            lg(x);
        }

        try {
            sock.destroy();
        }
        catch(x) {
            lg('on close' + x);
        }
    });

    sock.on('timeout', function() {
    });

});

server.on('error', function(err) {
});

server.on('close', function() {
});

server.listen(PORT, HOST);

Please try adding following code :
var TYPES = require('tedious').TYPES;
Since with the code given TYPES undefined

Make Sure TCP/IP is enable for SQL Follow the steps:

• Run SQL Server Configuration Manager.

• Go to SQL Server Network Configuration > Protocols for SQLEXPRESS.

• Make sure TCP/IP is enabled.

Then right-click on TCP/IP and select Properties, verify that under IP2, the IP Address is set to the computer's IP address on the local subnet, Make sure that TCP Dynamic Ports is blank & Make sure that TCP Port is set to 1433. (Tedious by default tries on this port)

Following is the code which is working for me (TESTED)

 var net = require('net'); var fs = require('fs'); var TYPES = require('tedious').TYPES; var Connection = require('tedious').Connection; var Request = require('tedious').Request; var HOST = '127.0.0.1'; var PORT = 7000; var timeout = 420000; // msec - *420000 //db conn config var config = { server: '127.0.0.1', userName: 'sa', password: '12345', options: { database: "NodeJSBenchmark", instanceName : "SQLEXPRESS" } }; var lg = function(message) { console.log(message); }; var server = net.createServer(); var connection = new Connection(config); connection.on('connect', function (err) { if (err) { return console.log('Error connecting:\\t' + err); } else { console.log('CONNECTED TO MS-SQL'); } }); connection.on('errorMessage', function (err) { if (err) { return console.log('Error connecting 2:\\t' + JSON.stringify(err)); } }); connection.on('infoMessage', function (info) { if (err) { return console.log('Information:\\t' + JSON.stringify(info)); } }); server.on('listening', function() { lg('Server listening on ' + HOST +':'+ PORT); }); server.on('connection', function (sock) { sock.setTimeout(timeout, function () { try { sock.end(); } catch (x) { lg('on end' + x); } }); function executeStatement() { //var storedProcName = '[NodeJSBenchmark].[dbo].[spINSERTsockdata]'; var storedProcName = 'spINSERTsockdata'; var request = new Request(storedProcName, function (err, rowCount) { if (err) { lg('Error on insert' + err); } else { lg(rowCount + ' rows2'); lg('SP fininshed running..'); } connection.close(); }); request.addParameter('sockdata', TYPES.VarChar, 'ping'); request.on('doneProc', function (rowCount, more, returnStatus) { lg('Rows Changed: ' + rowCount + 'Return Stat: ' + returnStatus); }); connection.callProcedure(request); } sock.setNoDelay(true); //sock.setEncoding('ascii'); // Identify incoming client sock.name = sock.remoteAddress + ":" + sock.remotePort sock.on('data', function (data) { try { //lg("CONNECTED: "+sock.name); //lg("INCOMING DATA: "+data); sock.write(data); executeStatement(); } catch (x) { lg(x); } }); sock.on('end', function (data) { try { sock.end(); } catch (x) { lg('on end' + x); } }); sock.on('error', function (err) { lg(err); }); sock.on('close', function (data) { try { sock.end(); } catch (x) { lg(x); } try { sock.destroy(); } catch (x) { lg('on close' + x); } }); sock.on('timeout', function () { }); }); server.on('error', function(err) { }); server.on('close', function() { }); server.listen(PORT, HOST);
