title: Pull the new data from website into the existing table with Scrapy
body: <p>I have a Scrapy project with Python. I pulled all data from website that I want. But I want to pull new data from website into the existing table instead of pulling the data from the beginning at each update. For example,</p>
  <pre><code>+---------------------------+
  | ID  |  Name   |   Job     |
  +---------------------------+
  | 01  |  Maria  |   Doctor  |
  +---------------------------+
  | 02  |  Silvia |   Teacher |
  +---------------------------+
  | 03  |  Lora   |   Soldier |
  +---------------------------+
  </code></pre>
  <p>With the new update, new data has been added to website. This data is:</p>
  <pre><code>+-------------------------+
  | ID  | Name   | Job      |
  +-------------------------+
  | 04  | Blanca | Engineer |
  +-------------------------+
  </code></pre>
  <p>So, when I run my code, I just want to pull the new data from website into the existing table. Not all over again.</p>
  <p>How can I do it?</p>
