Nevertheless PDO did'n convert a Null Value, when you select PDO::PARAM_STR as type. So PDO::PARAM_STR can handle Null-Values, but PDO::PARAM_INT can't. Test script: --------------- <?php $DB_HOST = 'localhost'; $DB_NAME = '***'; $DB_PASSWORD = '***; $DB_USERNAME = '***; $Dsn = 'mysql:host='.$DB_HOST.';dbname='.$DB_NAME; $Database = new PDO($Dsn, $DB_USERNAME, $DB_PASSWORD); $Database->setAttribute(PDO::ATTR_ERRMODE , PDO::ERRMODE_EXCEPTION); $Database->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_BOUND); $Sql = <<<SQL SELECT '', Null, 0, Null SQL; $Statement = $Database->prepare($Sql); $Statement->bindColumn(1, $Test1, PDO::PARAM_STR); // string(0) "" $Statement->bindColumn(2, $Test2, PDO::PARAM_STR); // NULL $Statement->bindColumn(3, $Test3, PDO::PARAM_INT); // int(0) $Statement->bindColumn(4, $Test4, PDO::PARAM_INT); // NULL $Statement->execute(); $Statement->fetch(); var_dump($Test1); var_dump($Test2); var_dump($Test3); var_dump($Test4); ?> Expected result: ---------------- string(0) "" NULL int(0) NULL Actual result: -------------- string(0) "" NULL int(0) int(0) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53132&edit=1
