Is there an ODBC guide?

[eluser]chicoNERD[/eluser]
I been working with MySQL and of course everything is great, but I thought this had the same support for ODBC instead I keep running in to all kind of problems.

is there a guide showing which functions work for ODBC? At school it is the only dataabase they allowing us to use.

I was trying to use,

Code:

$this->db->insert_id();
or
$this->db->affected_rows();

I believe is probably more of an Access limitation than it is CI's, is there a way to get this information?
