  rem -----------------------------------------------------------------------
  rem Filename:  backup.sql
  rem Purpose:  Generate script to do a simple on-line database backup.
  rem Notes:   Adjust the copy_cmnd and copy_dest variables and run from
  rem       sqlplus. Uncomment last few lines to do the actual backup.

  或者使用这个sql
