Javascript Scope Problem

Recommended Posts

    function MysqlName(sqlid, cb)
    {
        iHandle.mysql.handle.query("SELECT `Username` FROM `accounts` WHERE `UserID`= ?", [sqlid], function (err, rows, fields) {
            if (err) throw err;

               cb(rows[0].Username);
        });
    }

    var qwf = null;
        MysqlName(19, function (name) {
            qwf = name; 
            console.log("returning name: " + name) // return Firstname_Lastname (its ture)
        }
    );

    console.log(qwf); // RESULT NULL 

 

I did a function to pull the user name from the database. I can't assign it to global value. A very interesting mistake. How can I solve this?
