How do escape a MySQL LIKE statement in node-mysql? Something along the lines of "SELECT * FROM card WHERE name LIKE '%" + connection.escape(req.body.search) + "%'" Results in 'SELECT * FROM card WHERE name LIKE \'%\'hello\'%\'' Which is a syntax error. If I use the alternative syntax of connection.query("SELECT * FROM card WHERE name LIKE '%?%'", req.body.search, function () {}); Results in a similar syntax error. I've also tried connection.query("SELECT * FROM card WHERE name LIKE ?", '%' + req.body.search + '%', function () {}); Which just ends up escaping the '%' sign. Not sure why it's

I need a persistent MySQL connection for my Node web app. The problem is that this happens about a few times a day: Error: Connection lost: The server closed the connection. at Protocol.end (/var/www/n/node_modules/mysql/lib/protocol/Protocol.js:73:13) at Socket.onend (stream.js:79:10) at Socket.EventEmitter.emit (events.js:117:20) at _stream_readable.js:895:16 at process._tickCallback (node.js:415:13) error: Forever detected script exited with code: 8 error: Forever restarting script for 2 time info: socket.io started Here is my connection code: // Yes I know multipleStatements can be

I'm using the Mysql connector because I need to get some data from my database, but I'm having the following issue: I have two files server.js and dbConnection.js and I have a return in the dbConnection.js file which should return an array and it should show it in the server.js file. However, it prints out an undefined array. I don't understand what I'm doing wrong since I also tried to print out the array before reurning it in the dbConnection.js file and it's shown with the data. server.js: const express = require('express'); const dbConnection = require('./dbConnection.js'); app.get('/',

In my node.js, express app, I am making an ajax call with the superagent middleware. The call fetches database data in a complex array using the node-mysql middleware through quite a few database queries. Before pasting the code, I am trying to explain in words what I am trying to do although the code would suffice to say what it wants to do with the addition that all the asynchronous things inside the first callback should be done in the synchronous way. Explanation: Inside the callback of the first query , a for loop is executed to run the second query multiple times and after each loop, the

I have a python background and is currently migrating to node.js. I have problem adjusting to node.js due to its asynchronous nature. For example, I am trying to return a value from a MySQL function. function getLastRecord(name) { var connection = getMySQL_connection(); var query_str = "SELECT name, " + "FROM records " + "WHERE (name = ?) " + "LIMIT 1 "; var query_var = [name]; var query = connection.query(query_str, query_var, function (err, rows, fields) { //if (err) throw err; if (err) { //throw err; console.log(err); logger.info(err); } else { //console.log(rows); return rows; } }); //var

I am trying to figure out the best way to pass a mysql connection (using node-mysql) between my routes for express.js. I am dynamically adding each route (using a for each file loop in routes), meaning I can't just pass in the connection to routes that need it. I either need to pass it to every route or none at all. I didn't like the idea of passing it to ones that dont need it so I created a dbConnection.js that the routes can individually import if they need. The problem is that I dont think I am doing it correctly. As of now, my dbConnection.js contains: var mysql = require('mysql'); var db

I'm running a Node server connecting to MySQL via the node-mysql module. Connecting to and querying MySQL works great initially without any errors, however, the first query after leaving the Node server idle for a couple hours results in an error. The error is the familiar read ECONNRESET , coming from the depths of the node-mysql module. A stack trace (note that the three entries of the trace belong to my app's error reporting code): Error at exports.Error.utils.createClass.init (D:\home\site\wwwroot\errors.js:180:16) at new newclass (D:\home\site\wwwroot\utils.js:68:14) at Query._callback (D
