ODBC and LIKE gives weird query

Hi,

I'm trying to make a simple query in Codigniter v3.0.0 like this:

PHP Code:

$this->db->select("cats");
$this->db->from("pets");
$this->db->like("name", 'a', 'after'); 


And then show it:

PHP Code:

echo $this->db->get_compiled_select(); 


Result:

SELECT cats FROM pets WHERE name LIKE 'a%' {escape '!'}

For some reason CI adds {escape '!'} at the end. Which of course generates an error when I try to run the query.

Database config:

PHP Code:

$db['pyramid'] = array(
'dsn'   => 'pyramid',
'hostname' => '',
'username' => '',
'password' => '',
'database' => '',
'dbdriver' => 'odbc',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'WINDOWS-1252',
'dbcollat' => '',
    //'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
); 


I have tried to change the file system/database/drivers/odbc/odbc_driver.php like this:

PHP Code:

//protected $_like_escape_str = " {escape '%s'} "; Original
protected $_like_escape_str = ""; //Replaced with an empty string 


It seems to escape as it should, but I'm not sure if something else depends on this.

Is this a bug or is it just me that don't know how to use it properly?
Does anyone know how to fix this?
