How to write counter (variable) data from Unity to SQLite database??

Question

SQLite

Good day! I'm making a game on Unity, the player collects items that one of the variables counts. It is necessary to record the number of items found per game in the database. Can you please tell me how to record the number of items found in the database when the game is closed?
item counting and collection code:

using System.Collections;
using UnityEngine;

public class RaycastExample : MonoBehaviour
{
  public string ObjectTag;
  public bool MissionObjects;
  public int device;
  public GUIStyle style;

  void OnGUI () {

    GUI.Label (new Rect (20, 50, 200, 50), "Найденно устройств: " + device);
  }
  private void Update()
  {
    if (Input.GetMouseButtonDown(0))
    {
      Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
      RaycastHit hit;
      if (Physics.Raycast(ray, out hit))
      {
        if (hit.transform.CompareTag("PickUp"))
        {
          device++;
          Destroy(hit.transform.gameObject);
        }
      }
    }
  }
}
