I'm trying to insert values using mysql in nodejs. I had written the following code and installed MySQL support via npm,But canot to INSERT INTO the table due to this problem.

My code;

var mysql = require('mysql');



var values=randomValueHex(8);



var sql = INSERT INTO `activationkeys`(`activationKey`, `productId`) 

VALUES ( values ,'3');

con.query(sql, function (err, result) {

if (err) throw err;

console.log(1 record inserted);

});

My Error on terminal:

Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''3')'

How can i solve this problem?
