• setBlobAsBytes

  public void setBlobAsBytes​(PreparedStatement ps,

                      throws SQLException

  从接口复制的说明: 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.

  指定者:

  setBlobAsBytes 在接口中 LobCreator

  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

  public void close()

  从接口复制的说明: 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.

  指定者:

  close 在接口中 AutoCloseable

  指定者:
