title: Select id on grouped unique set of data
body: <p>My Problem is showing only id's of grouped unique Datasets. A simple example would serve best:</p>
  
  <pre><code>| id | color |
  --------------
  | 1  | red   |
  --------------
  | 1  | green |
  --------------
  | 1  | blue  |
  --------------
  | 2  | red   |
  --------------
  | 2  | green |
  --------------
  | 2  | blue  |
  --------------
  | 3  | red   |
  --------------
  | 3  | blue  |
  --------------
  | 3  | yellow|
  --------------
  | 3  | purple|
  --------------
  </code></pre>
  
  <p>Id 1 and id 2 have the same subset of data (red, green, blue), so the result table should only contain either 1 OR 2:</p>
  
  <pre><code>| id |
  ------
  | 1  |
  ------
  | 3  | 
  ------
  </code></pre>
  
  <p>I guess this relatively basic Problem was asked multiple times but I could not nail the specific keywords which would produce results.</p>
