You can't with MyISAM and executing from shell prompt.
Either alter the table type to BDB or Innobase
If you stick with MyISAM you can use a higher level language (perl,php) to check the
return value of each insert and handle the flow accordingly. If the 2nd insert fails,
you'll have to complement the first insert with a delete.
