#48724 [Opn]: getColumnMeta() doesn't return native_type for BIT, TINYINT and YEAR

ID: 48724 User updated by: an0nym at narod dot ru Reported By: an0nym at narod dot ru Status: Open Bug Type: PDO related Operating System: * PHP Version: 5.3.0 New Comment: Poor MySQLi developers... they've managed to solve this problem without specification. Poor you... you've spent sooo many time for nothing developing this function, which works in 35 of 38 cases - this stuff has no specification! Wait for a specification - you have a good excuse! Bye. Previous Comments: ------------------------------------------------------------------------ [2009-07-03 16:17:20] uw@php.net 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. ------------------------------------------------------------------------ [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] uw@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] uw@php.net libmysql and mysqlnd behave the same way.
