Greetings Monks.

I'm a beginning-intermediate Perl programmer and am currently working on a pretty simple DBI-based program. The focus of my question, however is not DBI-specific. Rather, it's a question about using (I believe) anonymous subroutines. What I want to do is catch it when one of my DBI statements fails. Depending on the error that caused the failure, I may want to just continue on or I may want to quit. My question is two-fold:

  1. Is what I'm trying to do actually an anonymous sub?
  2. Is this a good way to do what I want, or is there a better way?

Code follows, with questions in the comments:

# This is just an insert statement. What I want to do # is catch any errors, and then vary my actions based # on the error. Can I do this better? $newSeriesSth->execute() || &{ # is this an anonymous sub? if( $newSeriesSth->errstr =~ /duplicate/ ) { # this error is okay, i don't want to quit print "Trying to insert duplicate row.\n"; } else { # some other error, better safe to quit now. die("Unhandled error. DBI says: " . DBI->errstr); } };

Now, given that this is acceptable programming (which it may not be), the special bonus question is why do I get this error message while running this code?
Can't use string ("1") as a subroutine ref while "strict refs" in use at line 167 (Line 167 is the if(..) statement).
