Question

i am using codeigniter active records to execute a simple mysql query to select data in last one hour.

so my query is:

SELECT * FROM tablename WHERE added_datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR)

and my codeigniter code to form this query is:

$data=array(
            'added_datetime >='=>'DATE_SUB(NOW(),INTERVAL 1 HOUR)',

            );
            $query=$this->db->get_where('tablename',$data);

now the issue is codeigniter adds a single quotes around the DATE_SUB function and due to this the query not works on mysql server.

codeigniter produces:

SELECT * FROM (`tablename`) WHERE `added_datetime` >= 'DATE_SUB(NOW(),INTERVAL 1 HOUR)'

i also tried by adding FALSE as 3rd parameter in get_where but stil not worked

$query=$this->db->get_where('tablename',$data,FALSE);

it also produced the same query as above.
So please suggest me how to solve this issue.

-Thanks

Answer 1

Try doing something like this instead:

$this->db->where("added_datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR)", NULL, FALSE);
$query = $this->db->get('tablename');

$this->db->get_where(); doesn’t provide the function to unescaping your where clause.
