node-mysql

I'm on a shared hosting platform and would like to throttle the queries in my app so that if the total execution time exceeds a certain amount over a variable time period then I can make the app cool off and then resume later on. To do this I would like to find out how long each of my queries take in real time and manage it within the app and not by profiling it externally. I've seen examples in PHP where the time is recorded before and after the query ( even phpMyAdmin does this ), but this won't work in NodeJS or anything that runs the query asynchronously. So the question is: how would I go

I want to insert multiple rows into mysql thru node.js mysql module. The data I have is var data = [{'test':'test1'},{'test':'test2'}]; I am using pool pool.getConnection(function(err, connection) { connection.query('INSERT INTO '+TABLE+' SET ?', data, function(err, result) { if (err) throw err; else { console.log('successfully added to DB'); connection.release(); } }); }); } which fails. Is there a way for me to have a bulk insertion and call a function when all insertion finishes? Regards Hammer Ben You can insert multiple rows into mysql using nested arrays. You can see the answer from this

Im trying to connect to my mysql database with node-mysql. When i try the following code, I get this error: ERROR: Error: connect ETIMEDOUT does anyone know whats wrong?

I'm trying to put in multiple values into database using node-mysql in node. my source code engine.files.forEach(function(file) { torrentpath = file.path.replace(/&/g, "&").replace(/>/g, ">").replace(/</g, "<").replace(/"/g, """).replace(/'/g, "&apos;").replace(/\\/g, "/"); torrentFiles.push([ result.insertId, torrentpath, file.length ]); }); console.log(torrentFiles); app.mysql.query('INSERT INTO `files` (`torrentid`, `filename`, `filesize`) VALUES ?', torrentFiles, function(err, result) { if (err) throw err; }); The error I get is [ [ 11, 'ubuntu-14.04-desktop-amd64.iso', 1010827264 ] ]

I want to know the best way to return a bunch of JSON that is the result of some dependent mysql queries. app.get('/viewing/:id', function (req, res){ if(!req.cookies.user) { res.end('Requires Authenticated User'); } else { connection.query('SELECT blah blah where userId='+req.params.id, function (error, rows, fields) { Now we have a bunch of rows -- lets say 5. I need to go through each one and make another mysql query based on the data I just got. So I end up needing to repeat call (do I loop?) connection.query('SELECT id, firstName, lastName from users where id='+AN_ID_FROM_PRIOR_QUERY,

I am trying to connect to my Amazon RDS (MySQL) instance from a nodejs code hosted in Lambda using the "felixge/node-mysql" package. I need help to find out what I am doing wrong. I am getting "connect ETIMEDOUT" error. My code is hosted in Lambda and both Lamda and RDS are of the same account and region. I have also attached the RDSFullAccess Policy to the IAM role. RDS instance is also accessible from all IPs(no whitelist/blacklisted IPs). At the same time, I am able to connect from my local MySQL Workbench with same credentials. Here is my code: var connection = mysql.createConnection({

Which is the fastest method gets the query to MYSQL, and then comes back to output: console.log('queries finished', results)" Is there an even better method? Please explain your answer! Thanks! Method 1: var connection = mysql.createConnection({multipleStatements: true}); connection.query('SELECT ?; SELECT ?', [1, 2], function(err, results) { if (err) throw err; console.log('queries done', results); }); Method 2: const Db = mysql.createPool({ connectionLimit: 7, dateStrings: true, multipleStatements: true }); Db.getConnection(function(err, connection) { if(err) console.log(err); connection

My node.js app gives 5xx due to connection timeouts at random times. Here's how I connect and query: var mysql = require('mysql'); var config = { host: '172.10.1.1', port: 3306, user: 'user', password: 'pwd', database: 'mydb', connectionLimit: 15, queueLimit: 30 } var poolCluster = mysql.createPool(config); var queryDB = function(query, cb) { poolCluster.getConnection(function(err, connection) { if(err) { cb(err, null); } else { connection.query(query, function (err, rows) { connection.release(); cb(err, rows); }); } }); }; Also, in another alternate version, with connection pooling disabled,
