Description:
------------
An SQL stored procedure will return several rowsets when it contains several SELECT statements. In MySQL CLI client (`mysql'), if any statement raises SQL error, the procedure is aborted, HOWEVER, all rowsets prior to the error  are displayed.


In PHP, PDO->nextRowset() switches to subsequent rowsets, or indicates no more rowsets with `FALSE'. However, it ignores SQL errors in second and later SQL statements.

For reproduction, the following SQL procedures refer to nonexistent table `no_such_table'.

For reference SQL program for MySQL CLI client (`mysql') -- which correctly indicates errors.
<<input>>:

DROP TABLE IF EXISTS test_table;
DROP TABLE IF EXISTS no_such_table;
DROP PROCEDURE IF EXISTS test_procedure_error_at_first;
DROP PROCEDURE IF EXISTS test_procedure_error_at_second;

CREATE TABLE test_table (aaa int PRIMARY KEY);
INSERT INTO test_table SELECT 1 UNION SELECT 2;

DELIMITER $$

CREATE PROCEDURE test_procedure_error_at_first ()
	BEGIN
		SELECT * FROM no_such_table; -- will raise error
		SELECT * FROM test_table;
	END;

CALL test_procedure_error_at_first $$

CREATE PROCEDURE test_procedure_error_at_second ()
	BEGIN
		SELECT * FROM test_table;
		SELECT * FROM no_such_table; -- will raise error
	END;

CALL test_procedure () $$

Test script:
---------------
<?php


$pdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$pdo->exec('DROP TABLE IF EXISTS test_table');
$pdo->exec('DROP TABLE IF EXISTS no_such_table');
$pdo->exec('DROP PROCEDURE IF EXISTS test_procedure_error_at_first');
$pdo->exec('DROP PROCEDURE IF EXISTS test_procedure_error_at_second');

$pdo->exec('CREATE TABLE test_table (aaa int PRIMARY KEY)');
$pdo->exec('INSERT INTO test_table SELECT 1 UNION SELECT 2');

$pdo->exec('CREATE PROCEDURE test_procedure_error_at_first ()
	BEGIN
		SELECT * FROM no_such_table; -- will raise error
		SELECT * FROM test_table;
	END');
$pdo->exec('CREATE PROCEDURE test_procedure_error_at_second ()
	BEGIN
		SELECT * FROM test_table;
		SELECT * FROM no_such_table; -- this SHOULD raise error, but will be IGNORED
	END');

	# this would correctly indicate error raised by first SELECT * FROM no_such_table by raising an PDOException
#$pdo->query('CALL test_procedure_error_at_first()');


$st = $pdo->query('CALL test_procedure_error_at_second()');

	# this correctly fetches data from first SELECT * FROM test_table
var_dump($st->fetchAll());

	# this IGNORES error raised by second SELECT * FROM no_such_table
var_dump($st->nextRowset());
var_dump($st->fetchAll());

Expected result:
----------------
array(2) { [0]=> array(2) { ["aaa"]=> int(1) [0]=> int(1) } [1]=> array(2) { ["aaa"]=> int(2) [0]=> int(2) } }	# from var_dump($st->fetchAll());

PDOException: Base table or view not found: 1146 Table 'no_such_table' doesn't exist	# from $pdo->nextRowset()

Actual result:
--------------
array(2) { [0]=> array(2) { ["aaa"]=> int(1) [0]=> int(1) } [1]=> array(2) { ["aaa"]=> int(2) [0]=> int(2) } }	# from var_dump($st->fetchAll());
bool(false)	# from var_dump($st->nextRowset());
array(0) { }	# from var_dump($st->fetchAll());
