More Custom Error Handling
 
 
- It is also possible for HandleError to hide an error, to a limited degree
- 
- use set_err() to reset $DBI::err and $DBI::errstr
- alter the return value of the failed method
- 
 $h->{HandleError} = sub {
 my ($errmsg, $h) = @_;
 return 0 unless $errmsg =~ /^\S+ fetchrow_arrayref failed:/;
 return 0 unless $h->err == 1234; # the error to 'hide'
 $h->set_err(0,"");	# turn off the error
 $_[2] = [ ... ];	# supply alternative return value by altering parameter
 return 1;
 };
- 
- Only works for methods which return a single value and is hard to make reliable (avoiding infinite loops, for example) and so isn't recommended for general use!
- 
- If you find a good use for it then please let me know.
