using LIKE in SQL query with activerecord

You've got some interesting SQL there. I can help you make the SQL statement run better by not concatenating tables.

Try something like this:

SQL:

Code:

SELECT  
  p1.id,
  p1.name
FROM
  product_p1,
WHERE
  p1.id='".$idProd."'
  AND p1.id NOT IN (SELECT id FROM p2)
  AND p1.tags = p2.tags --//the like is unnecessary here (you're comparing two columns directly)

You may not be able to like two column like this.
Active Record:

Code:

$this->db->select('p1.id, p1.name');
$this->db->from('product_p1');
$this->db->where('p1.id', $idProd);
$this->db->where('p1.id', 'NOT IN (SELECT id FROM p2', FALSE);
$this->db->where('p1.tags', 'p2.tags');
$query = $this->db->get();
