Errors are most easly handled with block eval's:
eval
{
... # code here dies if there is an error
};
if( $@ )
{
... # code here can check $@ for the message
}
Whatever message the die passed out of the eval will be
in $@; which is guaranteed to be undef if nothing died.
This is the simplest way to deal with things since the
eval-ed code doesn't need to check for errors itself.
The DBI book and online doc's describe using this.
