Thxs.
actually i did some tests and when an error occurs it returns the sql generated so I think I managed to do What i wanted.
may be useless out of context but here is my final code, in case it brings light to someone else:
OPTION ACTIVE RECORD:
Code:
$this->db->select(" count(*) AS how_many_comments,
comment.id AS comment_id,
brand.name AS brand_name,
guitar.model AS guitar_model,
guitar.year AS guitar_year,
guitar.id AS guitar_id
");
$this->db->from('comment');
$this->db->from('guitar');
$this->db->from('brand');
$this->db->where("brand.id = guitar.brand_id");
$this->db->where("comment.guitar_id = guitar.id");
$this->db->group_by("comment.guitar_id");
$this->db->order_by('how_many_comments DESC, guitar_brand_name ASC');
$this->db->limit(10);
$data['query'] = $this->db->get();
$this->load->view('home_view', $data);
which does the same job as
Code:
$sql_right_column = "
SELECT
count(*) as how_many_comments,
comment.id as comment_id,
brand.name as guitar_brand_name,
guitar.model as guitar_model_name,
guitar.year as guitar_year,
guitar.id as guitar_id
FROM
comment,
guitar,
brand
WHERE
guitar.id = comment.guitar_id AND
brand.id = guitar.brand_id
GROUP BY comment.guitar_id
ORDER BY how_many_comments DESC, guitar_brand_name ASC
LIMIT 10;";
$this->db->query("SET NAMES 'utf8'");
$data['query_right_column'] = $this->db->query($sql_right_column);
For such queries, what is the best practice : use Active Record ? Why ?
Thanks for your advices.
Olivier.
