mysql problem help

Hi there,

  I am quite new to mysql. I have tried mysqldump to do DB backup. A strange
  thing is that I can create table field name including space and "-".   I can also dump the table without problem. But when I try to restore   the dumped txt file by "mysql < db_backup.sql", it complains that   "-" cause syntax error. It seems that either I change the name to   remove "-" or I have to add "`" before "-". However these two solutions are
  all awkward. Anyone knows how to work around this easily?   Thanks in advance!
