ERROR syntax error, unexpected '& quot; pr_employees.doctype_id, pr_e' (T_CONSTANT_ENCAPSED_STRING)

Good evening I have the following query in phalcon and I get this error:

Parse error: syntax error, unexpected '"pr_employees.doctype_id, pr_e' (T_CONSTANT_ENCAPSED_STRING) in /var/www/html/apiabacus/app/controllers/EmployeesController.php on line 27

code:

public function getAction ()     {       $ id = $ this- > request- > getQuery ('id');       $ fieldString = '';       $ joinString = '';       $ whereString = '';       $ sql = '';       $ params = [': id' = > $ id];

  $sql = "SELECT" "pr_employees.doctype_id, pr_employees.id, pr_employees.last_name,
   pr_employees.last_name2, pr_employees.name, pr_employees.bod, pr_employees.gender,

  $result = $this->db->fetchAll($sql,  Phalcon\Db::FETCH_ASSOC, $params);
  $this->jsonResponseAction(['data' => $result]);
}

and I really do not find that I miss it, thanks for your help.
