  Description copied from interface: `LobCreator`
  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.

  Specified by:
    `setBlobAsBytes` in interface `LobCreator`

    `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:
    `java.sql.SQLException` - if thrown by JDBC methods
  See Also:
    `PreparedStatement.setBytes(int, byte[])`

### setBlobAsBinaryStream

  Description copied from interface: `LobCreator`
  Set the given content as binary stream on the given statement, using the given parameter index. Might simply invoke `PreparedStatement.setBinaryStream` or create a Blob instance for it, depending on the database and driver.

  Specified by:
    `setBlobAsBinaryStream` in interface `LobCreator`
  Parameters:
    `ps` - the PreparedStatement to the set the content on

### 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.

  Specified by:
    `close` in interface `LobCreator`
