• setBlobAsBytes

  void setBlobAsBytes​(PreparedStatement ps,
                      int paramIndex,

                      byte[] content)
               throws SQLException

  Set the given content as bytes on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBytes or create a Blob instance for it, depending on the database and driver.

  参数:

  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

  抛出:

  SQLException - if thrown by JDBC methods

• close

  void close()

  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.
