Thank you for the report, and for helping us make PHP better. Previous Comments: ------------------------------------------------------------------------ [2008-02-19 14:56:01] uwendel at mysql dot com Description: ------------ What is PDO->query('SELECT ...', PDO::FETCH_COLUMN, $colno) supposed to do if you pass an invalid column number in $colno, e.g.: $stmt = $pdo->query('SELECT only_column FROM test', PDO::FETCH_COLUMN, -1); My preference would be to make PDO bail about the invalid offset. However, I do not know if this would work with all drivers. So, maybe its even technically not possible to make PDO emit a warning if the requested column is not available. In any case, I ask to update the manual and tell people about this edge case. Reproduce code: --------------- [EMAIL PROTECTED]:~/php53> sapi/cli/php -r '$pdo=new PDO("sqlite:/tmp/foo.db"); @$pdo->exec("DROP TABLE test"); $pdo->exec("CREATE TABLE test(id INT)"); $pdo->exec("INSERT INTO test(id) VALUES (1)"); var_dump($pdo->query("SELECT id FROM test", PDO::FETCH_COLUMN, -1)->fetchAll());' array(0) { } (Same with MySQL) Expected result: ---------------- If possible, make PDO bail out when calling query() with invalid column offsets. If that's not possible for technical reasons, please consider having a note about this in the manual. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44171&edit=1
