Hi guys i was wondering if we could add the MySQL REPLACE command in the /libraries/joomla/database/query.php.

I've been trying to do so, unsuccessfully.

I've been trying to copy the SET to REPLACE to submit the code here...
For example in line 1383 we have a code to SET:

/**
 * Add a single condition string, or an array of strings to the SET clause of the query.
 *
 * Usage:
 * $query->set('a = 1')->set('b = 2');
 * $query->set(array('a = 1', 'b = 2');
 *
 * @param   mixed   $conditions  A string or array of string conditions.
 * @param   string  $glue        The glue by which to join the condition strings. Defaults to ,.
 *                               Note that the glue is set on first use and cannot be changed.
 *
 * @return  JDatabaseQuery  Returns this object to allow chaining.
 *
 * @since   11.1
 */
public function set($conditions, $glue = ',')
{
    if (is_null($this->set))
    {
        $glue = strtoupper($glue);
        $this->set = new JDatabaseQueryElement('SET', $conditions, "\n\t$glue ");
    }
    else
    {
        $this->set->append($conditions);
    }

    return $this;
}
