ID: 48724 Updated by: u...@php.net Reported By: an0nym at narod dot ru Status: Open Bug Type: PDO related Operating System: * PHP Version: 5.3.0 New Comment:
You are free to write a patch. I refuse to work on stuff that has no specification and which may go into any direction. That typically ends up in a backwards compatibility nightmare, which in particular for an abstraction like PDO makes no sense to me. The patch may be rather simple. But watch out for different values returned by different MySQL versions. Previous Comments: ------------------------------------------------------------------------ [2009-07-03 15:39:20] an0nym at narod dot ru > libmysql and mysqlnd behave the same way. If this is decided to be considered as a bug it is not a mysqlnd bug. I agree. This is not a libmysql or mysqlnd bug. This is a PDO (or PDO_MySQL) bug. ------------------------------------------------------------------------ [2009-07-03 15:31:27] an0nym at narod dot ru Tell me then, why MySQLi is OK with all the types while PDO is not? Nevertheless, it is not just OK, but it is EQUAL in behaviour for all the types except TINYINT, BIT and YEAR. Don't tell me, please, MySQLi type and PDO native type refer to different things. I'm almost sure they don't. At least they shouldn't. <?php $PDO=new PDO('mysql:host=localhost;dbname=test','anyone','anyone'); $PDO->exec("CREATE TABLE `test`( `tinyint` TINYINT NOT NULL ,`smallint` SMALLINT NOT NULL ,`mediumint` MEDIUMINT NOT NULL ,`int` INT NOT NULL ,`bigint` BIGINT NOT NULL ,`decimal` DECIMAL NOT NULL ,`float` FLOAT NOT NULL ,`double` DOUBLE NOT NULL ,`bit` BIT(1) NOT NULL ,`date` DATE NOT NULL ,`datetime` DATETIME NOT NULL ,`timestamp` TIMESTAMP NOT NULL ,`time` TIME NOT NULL ,`year` YEAR NOT NULL ,`char` CHAR(1) NOT NULL ,`varchar` VARCHAR(1) NOT NULL ,`tinytext` TINYTEXT NOT NULL ,`text` TEXT NOT NULL ,`mediumtext` MEDIUMTEXT NOT NULL ,`longtext` LONGTEXT NOT NULL ,`binary` BINARY(1) NOT NULL ,`varbinary` VARBINARY(1) NOT NULL ,`tinyblob` TINYBLOB NOT NULL ,`mediumblob` MEDIUMBLOB NOT NULL ,`blob` BLOB NOT NULL ,`longblob` LONGBLOB NOT NULL ,`enum` ENUM('') NOT NULL ,`set` SET('') NOT NULL)"); $PDO->exec('INSERT INTO `test`(`tinyint`) VALUES(0)'); $PDO_statement=$PDO->query('SELECT * FROM `test`'); $PDO_fields=array(); for($i=0,$n=$PDO_statement->columnCount();$i<$n;++$i){ $PDO_fields[]=$PDO_statement->getColumnMeta($i); } $MySQLi=new mysqli('localhost','anyone','anyone','test'); $MySQLi_result=$MySQLi->query('SELECT * FROM `test`'); $MySQLi_fields=$MySQLi_result->fetch_fields(); $bug_fields=array(); for($i=0,$n=count($PDO_fields);$i<$n;++$i){ if(!isset($PDO_fields[$i]['native_type']) or constant('MYSQLI_TYPE_'.$PDO_fields[$i]['native_type'])!=$MySQLi_field s[$i]->type){ $bug_fields[]=$PDO_fields[$i]['name']; } } var_dump($bug_fields); $PDO->exec('DROP TABLE `test`'); ?> ------------------------------------------------------------------------ [2009-07-03 14:29:33] u...@php.net According to the test behaviour is not to set for certain types. This is what you get. ------------------------------------------------------------------------ [2009-07-03 14:28:26] u...@php.net libmysql and mysqlnd behave the same way.

Behaviour is not undefined. According to the link you provided, behaviour can be changed without notice, but on the moment of writing it is surely defined and has a bug. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
