title: Query All Tables For All Fields Containing Value
body: <p>So I'm trying to figure out where this value is stored in this database. Is there a way to query across all tables in the database and return all rows that contain a certain value where the field name that would contain that certain value is unknown?</p>
  
  <p>For example:</p>
  
  <pre><code>select * from * where unknown_field_name = 'x'
  </code></pre>
