Bug Type: PDO related
Operating System: *
PHP Version: 5.3.0
New Comment:
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`'); ?>

According to the test behaviour is not to set for certain types. This
is what you get.

libmysql and mysqlnd behave the same way. If this is decided to be
considered as a bug it is not a mysqlnd bug.

If function has expected behaviour for 35 of 38 cases (that's how many
different types has MySQL), it is rather clear how should it behave for
remaining 3.
> How can there be a bug if behaviour is undefined?
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.

Tested - this bug remains actual with PHP 5.3.0 and mysqlnd.
