Bug description: Error/Exception with PDO::fetch/fetchAll and disabled
ATTR_EMULATE_PREPARES
Description:
------------
When using PDO with MySQL, if ATTR_EMULATE_PREPARES is disabled, an
exception (or error if not using ERRMODE_EXCEPTION) is thrown if you try to
fetch() or fetchAll() a null result set (i.e. after INSERT, UPDATE etc.).
However, if ATTR_EMULATE_PREPARES is enabled, the exception/error is not
triggered.
Clearly fetch on a null result set is redundant, but either it should
throw an exception/error or it shouldn't, regardless of the state of
ATTR_EMULATE_PREPARES.
Reproduce code:
---------------
$db = new PDO( $dsn, $username, $password );
// enables exceptions
$db->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// disable emulation <--- this triggers the problem
$db->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );
$sql = 'INSERT INTO TestTable VALUES ( NULL )';
$query = $db->prepare( $sql );
if( $query->execute() )
{
$results = $query->fetchAll( PDO::FETCH_ASSOC );
}
$query->closeCursor();
Expected result:
----------------
Either an exception/error should be thrown in both cases, or neither.
Actual result:
--------------
'PDOException' :: 'SQLSTATE[HY000]: General error: 2053 '
