将MySQL查询转换为Codeigniter Active Records

Question

I`m new to codeigniter and I like to convert following MySQL queries into Codeigniter Active Record Queries.

'SELECT name, address, detail, status, startdate, FROM job_step WHERE username = '$_SESSION[username]'  and 'status'===0'

PS- job_step table consists of several columns, but I only need few not the entire table, addition to that information should filter according to session name and status (TINYINT which has 1 and 0).

Answer 1

$this->db->select('name, address, detail, status, startdate')
              ->from('job_step')
              ->where(array('username' => $_SESSION['username'], 'status' => 0))
              ->get()
              ->result();

This will get you an object. If you want array just change last line to ->result_array();

Answer 2

You can write the above query as:

$this->db->select('name, address, detail, status, startdate');
$this->db->where('username',$_SESSION['username']);
$this->db->where('status','0');
$rset=$this->db->get('job_step');
$result=$rset->result();
