Answer 1

Unless I misunderstand you, AutoExecute doesn't seem right for the job. If you need to do a one-time conversion of all records in your table I would just rename the columns.
ALTER TABLE `users`
CHANGE COLUMN `lastname` `firstname` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER `id`,
CHANGE COLUMN `firstname` `lastname` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER `firstname`;
Or in PHP/ADODB:
$sql = "ALTER TABLE `users`
CHANGE COLUMN `lastname` `firstname` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER `id`,
CHANGE COLUMN `firstname` `lastname` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER `firstname`;";
if (($result = $conn->Execute($sql)) === false)
exit($sql.'<br />'.$conn->errorMsg());
If you need to target specific records you could use a temporary variable.
$sql = "UPDATE users
SET firstname=(#temp:=firstname), firstname = lastname, lastname = #temp
WHERE id=2";
if (($result = $conn->Execute($sql)) === false)
exit($sql.'<br />'.$conn->errorMsg());
