title: Group data from 3 SQL tables
body: <p>I want to match some sql entries and group them like the fallowing:</p>
  <p>workers_table</p>
  <pre><code>ID    |   worker
  ------+--------------
  1     |    Smith
  2     |    John
  3     |    Luke
  </code></pre>
  <p>workers_tools_usage</p>
  <pre><code>worker_id    |   tool_id
  -------------+----------
  1            |    1
  1            |    2
  1            |    3
  3            |    1
  </code></pre>
  <p>tools_table</p>
  <pre><code>tool_id    |   name
  -------------+----------
  1            |    hammer
  2            |    wrenches
  3            |    drill
  4            |    screwdriver
  </code></pre>
  <p>And my desired match should look like this:</p>
  <pre><code>worker       |   tool
  -------------+----------
  Smith        |    hammer,wrenches,drill 
  Luke         |    hammer
  </code></pre>
  <p>Is this possible using Mysql ? Tried some UNION but no luck.</p>
