title: How to select data from jsonb column?
body: <p>I have got one column with type jsonb. The data in this column looks as below</p>
  
  <pre><code>{
      "random_number1":
      {
          "random_number2":
          {
              "Param1": 2,
              "Param2": 0,
              "Param3": 0,
              "Param4": 6,
              "Param5": 3
          }
      }
  }
  </code></pre>
  
  <p>How to write select for this column if I want f.e. all rows where "Param3"=6 ?
  I tried something like that</p>
  
  <pre><code>SELECT * FROM table WHERE column-&gt;'Param3' @&gt; '6'::jsonb;
  </code></pre>
