Flexigrid CodeIgniter Implementation

[quote author="mosos" date="1228144816"]quick search function wont work @oracle with active record. any solution?[/quote]

I've success running flexigrid with oracle db (with CI version 1.7) but that searching still not running well. I've changed files:
database\drivers\oci8\oci8_driver.php line 549-556 for clear escape string when we use active record

Code:

if (strpos($item, '.') !== FALSE)
        {
            $str = str_replace('.',

$this->_escape_char.'.'.$this->_escape_char, $item);            
        }
        else
        {
            $str=$item;
        }

Column of Oracle tables usually use Capital character so I've changed:
model/ajax_model line 44

Code:

$return['record_count'] = $row->RECORD_COUNT;

and controller/ajax line 29-35

Code:

$record_items[] = array($row->ID,
            $row->ID,
            $row->ISO,
            $row->NAME,
            '<span

style=\'color:#ff4400\'>'.addslashes($row->PRINTABLE_NAME).'</span>',
            $row->ISO3,
            $row->NUMCODE,
            '<a ><img >config->item('base_url').'public/images/close.png\'></a> '
            );

Could anyone give me more solution to running that search feature. Tanks
