php – zend update语句,不更新数据库行

$id = $this->user->id;
$data['last_cust_code']     = $a_Search['custcode'];
$data['last_paid_filter']   = $a_Search['paid'];
$data['last_unpd_filter']   = $a_Search['unpaid'];
$data['last_group_field']   = $a_Search['grouping'];
$data['last_session_code']  = $a_Search['session'];
$out = $objDb->update('tblusrusers',$data,array("id = ?"=>$id));

分析器输出

UPDATE `tblusrusers` SET `last_cust_code` = ?,`last_paid_filter` = ?,`last_unpd_filter` = ?,`last_group_field` = ?,`last_session_code` = ? WHERE (id = '70')

Array
(
    [1] => TESTAAA
    [2] => N
    [3] => N
    [4] => 1
    [5] => 19993E
)

当我直接通过mysql客户端更新它正确更新.

重要提示：当我通过查询选择输出时,我能够看到更新,但不是通过phpmyadmin.does它与提交语句有关,我的意思是我的自动提交是假的？对于其他一些查询使用事务将它会影响我上面的更新查询吗？请帮忙
