note 104647 added to book.pdo

I am in despair! So, I have mySQL table: CREATE TABLE categories( id INT(11), parent_id INT(11), name VARCHAR(155), note VARCHAR(155) INSERT INTO categories (ID, parent_id, name, note) VALUES (1, 0, 'test', 'test note'); and simple php code: $dsn = 'mysql:dbname=trader;host=localhost'; $pdo = new PDO($dsn, 'root', '', array(PDO::ATTR_PERSISTENT=>DB_PERSISTENCY)); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sel = 'SELECT * FROM categories;'; $array = $pdo->query($sel)->fetchAll(PDO::FETCH_ASSOC); print_r($array); Output Result: Array ( [id] => 1 [parent_id] => 0 [categories] => 'test' [trader] => 'testnote' ) !!! look at the array of field names!!! Why this? Field 3 = "categories"??? (table name) Field 4 = "trader"??? (db name) Why this error may occur?
