PHP PDO Fetch_Assoc not returning correctly

I have searched, and maybe I am searching for the wrong thing, but I need help with the below code. I must be missing something... Database Class: ``` class Database { private static $link = null; private static function dbLink() { if(self::$link) { return self::$link; } $dsn = null; switch(DB_DRVR) { case 'mysql': $dsn = DB_DRVR . ":host=" . DB_HOST . ";dbname=" . DB_NAME; break; } self::$link = new PDO($dsn, DB_USER, DB_PASS); return self::$link; } public static function fetchAssoc($sql) { $stmt = self::query($sql); $result = array(); $result = $stmt->fetch(PDO::FETCH_ASSOC); return $result; } public static function __callStatic($name, $arguments) { $callback = array(self::dbLink(), $name); return call_user_func_array($callback, $arguments); } } ``` Portion of code returning error: ``` $sql = "SELECT group FROM users WHERE username='ryan';"; $dbSQL = Database::fetchAssoc($sql); echo $dbSQL['group']; ``` Database setup: - id(auto_increment, primary) - name(tinytext) - username(tinytext) - password(tinytext) - salt(tinytext) - email(tinytext) - group(tinytext) - privileges(tinytext) I'm receiving the following error: ``` Fatal error: Call to a member function fetch() on a non-object in C:\public_html\kernel\database.php on line 38 ``` However the odd part is if I change the SQL to: ``` $sql = "SELECT * FROM users WHERE username='ryan';"; ``` I don't get the error, it displays properly, and if I change the SQL statement to: ``` $sql = "SELECT username FROM users WHERE username='ryan';"; ``` and call $dbSQL['username'] it works fine using the function above. My Question: How come when I try to use the 'group' column in my $dbSQL array, I am receiving an error, but when I try to use the 'username' column, everything runs fine. What am I missing?
