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.

I agree. This is not a libmysql or mysqlnd bug. This is a PDO (or
PDO_MySQL) bug.

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.
