Description:
------------
---
From manual page: http://www.php.net/mysqli.release-savepoint
---

The documentation states:

mysqli::release_savepoint -- mysqli_release_savepoint — Rolls back a transaction to the named savepoint

However, this is not what RELEASE SAVEPOINT does (http://dev.mysql.com/doc/refman/5.0/en/savepoint.html) (and a quick test verifies that this function does not roll back either)

Here is a test to confirm. The table ends up as:

apple
potato
orange

"pomegranate" is missing, because it has been rolled back, but potato is included, because release_savepoint() actually has the effect of "forgetting" that savepoint, but NOT rolling back the work.

$db->begin_transaction();
$db->query('INSERT INTO utility_belt SET item="apple"');
$db->savepoint('vegetables');
$db->query('INSERT INTO utility_belt SET item="potato"');
$db->release_savepoint('vegetables');
$db->savepoint('nope');
$db->query('INSERT INTO utility_belt SET item="pomegranate"');
$db->query('ROLLBACK TO nope'); // No rollback to savepoint function..?
$db->query('INSERT INTO utility_belt SET item="orange"');
$db->commit();

It's interesting too that there appears to be no function to ACTUALLY rollback to a given savepoint.
