format to write query in codeigniter - php

Question

I am new with codeigniter.
I have following query, each query having different table name and different where condition.
Can i make this query in single query or is it correct way to execute query.
i have to execute all this query.
$q = $this->db->where('id', $st)->update('st_info', array(
'status' => 0,
'updated_time' => $this->info_model->getTime(),
'updated_ip' => $this->info_model->getIP()
));
$q = $this->db->where('verid', $vid)->update('st_version', array(
'status' => 0,
'updated_time' => $this->info_model->getTime(),
'updated_ip' => $this->info_model->getIP()
));
$q = $this->db->where('id', $id)->update('st_raw', array(
'status' => 0,
'updated_time' => $this->info_model->getTime(),
'updated_ip' => $this->info_model->getIP()
));

Answer 1

Since you are using same columns for all the tables, i prefer to work with below method,
$data = array(
'status' => 0,
'updated_time' => $this->info_model->getTime(),
'updated_ip' => $this->info_model->getIP()
);
$q = $this->db->where('id', $st)->update('st_info', $data);
$q = $this->db->where('verid', $vid)->update('st_version', $data);
$q = $this->db->where('id', $id)->update('st_raw', $data);

Answer 2

That is correct you cannot combine all that into a single query.

Answer 3

Try this:
$data=array(
'status' => 0,
'updated_time' => $this->info_model->getTime(),
'updated_ip' => $this->info_model->getIP()
));
$this->db->where('id',$st);
$this->db->update('st_info', $data);
$this->db->where('verid',$vid);
$this->db->update('st_version', $data);
$this->db->where('id',$id);
$this->db->update('st_raw', $data);

Answer 4

Create a single function
public function update($table,$where,$data)
{
$this->db->where($where);
$this->db->update($table,$data);
}
Now call this function like this from controller
function update_call()
{
$data['status'] = 0;
$data['updated_time'] = $this->info_model->getTime();
$data['updated_ip'] = $this->info_model->getIP();
$where['id'] = $st;
$table = 'st_info';
$this->model_name->update($table,$where,$data);
unset($where);
unset($table);
$where['verid'] = $vid;
$table = 'st_version';
$this->model_name->update($table,$where,$data);
unset($where);
unset($table);
$where['id'] = $id;
$table = 'st_raw';
$this->model_name->update($table,$where,$data);
}
