      ps - the PreparedStatement to the set the content on
      paramIndex - the parameter index to use
      content - the content as byte array, or null for SQL NULL
      Throws:
      SQLException - if thrown by JDBC methods

    • close

      public void close()
      Description copied from interface: LobCreator
      Close this LobCreator session and free its temporarily created BLOBs and CLOBs. Will not need to do anything if using PreparedStatement's standard methods, but might be necessary to free database resources if using proprietary means.

      NOTE: Needs to be invoked after the involved PreparedStatements have been executed or the affected O/R mapping sessions have been flushed. Otherwise, the database resources for the temporary BLOBs might stay allocated.
