title: Is there a possibility to make text field in SQLite to point to a different field?
body: <p>I have a DB which I access through SQLite. 
  I have a text field with a url to the media file inside that field (named here UrlField). </p>
  
  <p>Is there a possibility (after downloading the files and inserting them as blobs to different table - Blob table with BlobValue field) to make UrlField value point to BlobField value and to access blobs through UrlField?</p>
  
  <p>Thanks,
  JRoma</p>
