Bug description: PDO does not throw Exception
Description:
------------
The following code leads to a "Unknown Command" Error (because I tried to
use PDO with a 5.0 libmysql to connect to a 3.23 mysqld), but for any
reason this does not throw an Ecxeption, though I used:
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
Why doesn't PDO throw an Exception here?
Reproduce code:
---------------
<?php
try {
$dbh = new PDO('mysql:host=localhost;dbname=test', 'user', 'pass');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$result = $dbh->query('SELECT * FROM test');
var_dump($dbh->errorInfo());
}
catch(PDOException $e){
die($e->getMessage());
}
?>
Expected result:
----------------
should throw a PDOEception ("Unknown Command"), which is caused by
PDO::query().
Actual result:
--------------
Does not throw any exception, only $dbh->errorInfo() gives some info here.
$dbh->query() return FALSE
$dbh->errorInfo() returns error "Unknown Command"
$dbh->getAttribute(PDO::ATTR_ERRMODE) returns "2"
which is == PDO::ERRMODE_EXCEPTION
shouldn't PDO throw an Exception here? Seems to ignore the errormode set
by $dbh->setAttribute(). Before calling $dbh->query() and after calling
$dbh->setAttribute() $dbh->errorInfo() returns no error.
I started a thread on php.pecl.dev last week about a problem with using
PDO_MYSQL linked against a 5.0 libmysql with a 3.23 mysqld. The reason for
the error seems to be, that PDO_MYSQL uses "prepare" internally, which is
not supported by mysqld <4.1:
