title: MYSQL subset operation
body: <p>Is there a way to achieve something like:</p>
  
  <pre><code>SELECT *
  FROM tb_values
  WHERE (value1, value2, value3) SUBSET_OF
      ( SELECT value
        FROM tb_value
        WHERE isgoodvalue = true
      )
  </code></pre>
  
  <p><strong>More information:</strong>
  I have a table called projects. Each project has tags. A tag can be shared by multiple projects. There is a mapping table called projectTagMap.  Now users use tags to filter the projects. Tags are selected using checkboxes on the UI. So a user selects several tags to filter the projects. Am supposed to select the projects from projects table that contains all the tags selected by the user. </p>
