Active record and date in where statement

[eluser]smilie[/eluser]
Hi all,

Following code:

Code:

$query = $this->db1->query("SELECT count(*) FROM table WHERE created >= '".date("Y-m-d H:i:s",strtotime("-1 day"))."'");
$res = $query->num_rows();

is working.

However, with active record code:

Code:

$this->db1->where('created >=',date("Y-m-d H:i:s",strtotime("-1 day")));

I receive no results from the query... Why is this?
I have tried to escape it - but no prevail.

Thanks!
Smilie
