It may have an option to not die on error (DBI has one), and you could then
test for and manually catch exceptions. However, the (I'm assuming) default
behavior is a good thing, you just need to trap it. Here's one way to do it:

my $var;
eval {
    $var = $dbixclass_obj->dowhatever( ... );
    1;
} or do {
    # handle exception
    my $error = $@;
    # do whatever you want with the error.
    # the $error var holder is so that, if you make another call here,
    # it's results won't flush the $@ variable.
};

There's loads of exception handling modules out there that aid in this
stuff or make throwing exceptions better/easier/etc, but that's the basics.

If your'e already doing something like that and it's not getting caught or
something, please provide sample code or more details.
