in reply to Have a sort of trouble.

Hi, $a and $b already contain the file path; if you want to sort by the path, just use them:

What about this?

for my $apache_file ( sort { $a cmp $b } keys( %{ $merge_structure{ ap +ache_log }\ } ) ) { print "$apache_file\n"; }

If you don't want to sort by the file path you should tell us, by what you want to sort.

The file path is the key, you are sorting by the value, whatever that may be...

    Duh, thank you! That's what happens when you don't write perl for a year :)

[erix]: then you might as well send that patch to the DBIC guys :)
[Corion]: erix: Yeah, I just found that it has no documentation at all on how to circumvent/ eliminate "1+n SELECTs" by building a local hash... I guess I have to make ->has_many do the hash lookup instead of doing the SQL query. But as the problem ...
[Corion]: ... has only manifested itself so far through the puzzled questions of other bystanders, I won't go deeper at this time. But the DBIx::Class documentation could well do with a document on how to make "it" (that is, ORMs in general) faster ;)
[Corion]: I find that DBIx::Class, like most ORMs makes things easy until they become performance critical and then makes it horribly hard to change things because the design is highly inflexible if you don't already know about the problems of 1+n :-/
[choroba]: that's why I don't like similar libraries. They pretend you don't have to learn SQL, but in the end, you have to learn how SQL plus to overcome their own limitations
[Corion]: "Just write the proper SQL beforehand" is of course the appropriate solution, but if you did that, you wouldn't/couldn't use DBIx::Class either. At least not in an obvious (to me) way.
choroba scratches a "how"
[Corion]: choroba: Exactly... But maybe that's just because I'm old and grumpy ;)
