title: Oracle: export a table with blobs to an .sql file that can be imported again
body: <p>I have a table "Images" with two fields:</p>
  
  <ul>
  <li>Name VARCHAR2</li>
  <li>Data BLOB</li>
  </ul>
  
  <p>I would like to export that table to a .sql file which I could import on another system. I tried to do so using the "Database unload" assistant of Oracle SQL Developer. However the generated file does just have the content for the names in it but not the data. Thus after importing I would end up with all the names but the data field would be null everywhere.</p>
  
  <p>I'd really prefer it just to be one file (I saw some examples that included dumping the data to one file per field on the fs...)</p>
  
  <p>Is it possible to generate such a script with SQL Developer? or is there any other way/tool to do so?</p>
