Handling errors the smart way

• For simple applications immediate death on error is fine

• For more advanced applications greater control is needed

• Life after death:

  $h->{RaiseError} = 1;
  
  eval { … $h->method; … };
  if ($@) { … }
  

• Bonus prize

  • Other, non-DBI, code within the eval block may also raise an exception that will be caught and handled cleanly

eval { } is very cheap: 4.4 microseconds on a SPARC Ultra 5.
