codeigniter query builder code example
Example 1: codeigniter raw query
$sql="Select * from my_table where 1";
$query = $this->db->query($SQL);
return $query->result_array();
Example 2: codeigniter 3 insert
$data = array(
'title' => 'My title',
'name' => 'My Name',
'date' => 'My date'
);
$this->db->insert('mytable', $data);
// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
Example 3: codeigniter where_not_in
$names = array('Frank', 'Todd', 'James');
$this->db->where_not_in('username', $names);
// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')
Example 4: codeigniter where order by
$this->db->select('ae_users.employee_id, ae_users.emp_name, ae_users.emp_name2, ae_users.emp_name3');
$this->db->from('ae_users');
$this->db->where_in('ae_users.employee_id',$employee_ids);
$this->db->_protect_identifiers = FALSE; // stop CI adding backticks
$order = sprintf('FIELD(ae_users.employee_id, %s)', implode(', ', $employee_ids));
$this->db->order_by($order);
$this->db->_protect_identifiers = TRUE;
$query =$this->db->get();
// echo '<pre>'; print_r($this->db->last_query());exit;
if ($query->num_rows()) {
return $query->result_array();
} else {
return 0;
}
Example 5: codeigniter insert
$data = array(
'title' => 'My title',
'name' => 'My Name',
