How to retrieve database error from CodeIgniter

Why over-complicate it?

Code:

$this->db->simple_query

Does the same thing (faster) and doesn't return ANY error: so use with caution!

This is a public method on line 440 of DB_driver (in 1.7.0) anyway. ;-)

There's a very good argument to allow PHP to ignore duplicate inserts in some rare cases - and it's quicker to ignore the error in the same way as you might use "@" in PHP if you know it might happen.
