'OR Like' MySQL - Maybe a bug?

[eluser]N3XT0R[/eluser]
I got a solution, maybe not the best, but currently i think is every solution better:

CI_DB_active_record Class changes:

Code:

//Declaring and initialization of $ar_or_like
after Line 35 added.
var $ar_or_like                         = array();

//Adding array to the Reset-Function for Select.
after line 2032 added (Reset-Funktion):
'ar_or_like'                    => array(), // Zeile eingefügt.

//Adding array to the Reset-Function for write.
after line 2002 added:
'ar_or_like'                    => array(), // Zeile eingefügt.


after line  617 added:
array_push($this->ar_or_like, array($field, $match));

/**
* Check if or_like is set and replace the first "AND" (which will be everytime set
* when more than 0 like are setted too) with "OR", when ar_or_like is higher than 0.
*/
Line 1746 -  1754 replaced with:
if (count($this->ar_like) > 0 && count($this->ar_or_like) == 0)
{
if (count($this->ar_where) > 0)
{
  $sql .= "\nAND ";
}elseif(count($this->ar_or_like) > 0){
  $sql .= "\nOR ";
}

$sql .= implode("\n", $this->ar_like);
}

Notice:
Only done changes for select, this solution is not working for replace into or anything else.
Maybe it is helpful for another person, too.
