Equal in select does not work as expected

I found a funny behaviour using equal with pdo. I checked several select-statements in phpmyadmin and pdo and the results vary. Has someone a idea whats wrong?

$sql = "select * from fenster where fenster > 'news'"; //works ok $sql = "select * from fenster where fenster < 'news'"; //works ok $sql = "select * from fenster where fenster <= 'news'"; //works ok $sql = "select * from fenster where fenster >= 'news'"; // news is not in result $sql = "select * from fenster where fenster = 'news'"; // news is not in result $stmt = $db->prepare($sql); $stmt->execute();

$feldName = array_keys($stmt->fetch(PDO::FETCH_ASSOC));

while($data = $stmt->fetch()) { var_dump($data); }

-------------Problems Reply------------

I found the reason myself. The $feldName = array_keys($stmt->fetch(PDO::FETCH_ASSOC)); did read the missing row, so it did not show afterwards. So I have to find a workaround.
