Bug description:PDO converts (int)0 to NULL
Description:
------------
PDO Driver for MySQL, client library version 5.0.84
When using the bindColumn method of the pdo statement object, PDO converts
the value Null to the number 0, if you set the type to PDO::PARAM_INT.
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)
