DAO
var executeQuery = function(query,callback) {
var connection = mysql.createConnection({
host: 'localhost',
user: 'root',
password: '',
database: 'testt'
});
connection.connect();
connection.query(query, function(err, rows, fields) {
if (err) throw err;
connection.end();
console.log("Here in Dao: " + rows[0].mobile_phone);
callback(rows[0].mobile_phone);
});
};
module.exports = {
executeQuery: executeQuery
};
Model
var DAO = require('../lib/database.js');
module.exports = {
getuser : function(id,callback){
var User = DAO.executeQuery("select mobile_phone from ms_customer WHERE id = " + id, function(mobile_phone){
// var json = JSON.stringify(User);
console.log("Return from Dao = " +User);
callback(mobile_phone);
});
}
}
Controller
test : function(req,res){
var customerModel = require('../model/customer');
customerModel.getuser('0001', function(mobile_phone){
console.log("return from model_user = " + mobile_phone);
});
},
i always got error = 'ER_BAD_FIELD_ERROR: Unknown column '0001' in 'where clause''

Answer 1

i think error at query statement, please try this.
getuser : function(id,callback){
var User = DAO.executeQuery("select mobile_phone from ms_customer WHERE id = '" + id + "';", function(mobile_phone){
// var json = JSON.stringify(User);
console.log("Return from Dao = " +User);
callback(mobile_phone);
});
}
}
