I am trying to get case number value to be checked in my database and if that exists then to get redirected to another page

I have created a form module and as I am new with coding in Drupal 8,I need help to know how to fire queries in the function.

public function validateForm(array &$form, FormStateInterface $form_state) 
 $cname = $form_state->getValue('cname');
 $email = $form_state->getValue('email');
 if (strlen($cname) < 12) 
 $form_state->setErrorByName('cname', $this->t('The title must be at least 12 characters long.'));
 
 if (!valid_email_address($email)) 
 $form_state->setErrorByName('email', $this->t('Please Enter Valid Email Id.'));
 
 

public function submitForm(array &$form, FormStateInterface $form_state) 
 $cname = $form_state->getValue('cname');
 $email = $form_state->getValue('email');
 $name = $form_state->getValue('name');
 drupal_set_message($this->t('You specified a Case Number of %cname.', ['%cname' => $cname]));
 drupal_set_message($this->t('You specified a Email of %email.', ['%email' => $email]));
 drupal_set_message($this->t('You specified a Name of %name.', ['%name' => $name]));
