是否可以在CodeIgniter中使用手动SQL查询？

Question

Ive been learning codeigniter and I like their database methods. However I would prefer to write my own SQL queries. When I try to write a manual query it results in a codeigniter error.

Ive searched around if it is possible however I cant find much info on the subject. The closes Ive come to an answer was this .

Question

Is it possible to disable the build in Codeigniter database methods, and perform my own sql queries. Or run my own sql queries alongside CodeIgniter's database class?

If yes, how would I go about configuring this?

Thanks in advance

Answer 1

From https://www.codeigniter.com/userguide3/database/results.html , you can use query method from db library.

$query = $this->db->query("YOUR QUERY");

foreach ($query->result() as $row)
{
        echo $row->title;
        echo $row->name;
        echo $row->body;
}

Answer 2

$this->db->query('selec * from your_table');

you can use like this your core query ...

`

$sql = "select model,varient,(select color from mtbl_colors where
        mtbl_colors.colorid=mtbl_vehicles.colorid) as color from mtbl_vehicles";


$sql .= " where $where_clause = ?";
 $result = $this->db->query($sql, $where_value);
