Active Record method chaining syntax

[eluser]jmb727[/eluser]
[quote author="DrDave" date="1306198989"]Can someone tell me the correct syntax for chaining an active record update statement, or where I can find examples? I want to chain this just to get a handle on how chaining works:

Code:

$data = array( 'user_color' => 'blue' );
$this->db->where('user_id', $user_id);
$this->db->update('user', $data);

Thanks![/quote]

What do you mean by chaining?
Do you mean updating multiple table fields using an array with keys/values representing fields/new values?
