Actually I want to make it clear this thing that below Two query are given. is there any overhead for server to excecute query.? what will be efficient exection of query.?
Query 1
$query = 'select n.id, n.title as newsTitle, n.short_description, n.news_slug, c.id as catId, c.name as categoryName, ig.image_name from news n, tpaper_current_news cn LEFT JOIN news_image ni ON (cn.news_id = ni.news_id) LEFT JOIN image_gallery ig ON (ni.image_id = ig.id), category c, news_category nc where cn.type = "breaking" AND cn.status = "Active" AND cn.news_id = n.id AND cn.news_id = nc.news_id AND nc.category_id = c.id AND n.date_publish like "%'.$date.'%" ';
if($is_tpaper != '') {
$query .= ' AND n.is_tpaper = "'.$is_tpaper.'" ';
}
$query .= ' order by cn.sort_order DESC ';
if($no_of_news != '') {
$query .= 'LIMIT 0 , '.$no_of_news; //n.date_publish DESC,
}
return $this->db->query($query);
Query 2
$conditions = array(
'cn.type' => 'breaking',
'cn.status' => 'Active'
);
$like = array(
'n.date_publish' => $date
);
$param = 'n.id, n.title as newsTitle, n.short_description, n.news_slug,c.id as catId, c.name as categoryName';
if($date != '') {
if(!empty($where))
$this->db->where($where);
$this->db->select($param)->
from('tpaper_current_news cn')->
join('news n','cn.news_id = n.id')->
join('news_category nc','n.id = nc.news_id')->
join('category c', 'nc.category_id = c.id');
if(!empty($conditions))
$this->db->where($conditions);
if(!empty($like))
$this->db->like($like);
if($is_tpaper != '')
$this->db->where('n.is_tpaper', $is_tpaper);
$this->db->order_by('n.id', 'DESC')->
limit(5, 0);
return $this->db->get();
