title: Inserting blob in oracle DB where I don't have permissions to create tables
body: <p>I was looking at stack overflow for ways to insert blob data in oracle and found some ways to do so (<a href="https://stackoverflow.com/questions/43432415/how-to-insert-a-picture-into-blob-column-in-oracle-table-using-insert-syntax">How to insert a picture into BLOB column in Oracle table using INSERT syntax?</a>).<br>
  I am trying to insert a blob already retrieved in my oracle DB on an environment where I cannot create new tables. How do I insert this blob that I have? Can I do something where I convert the BLOB I have to raw data and then insert?
      Insert into TABLE values (1234,utl_raw.cast_to_raw(blob_data))
  Will the data be unmodified? Thanks!</p>
