sub

See the current Perl documentation for sub.

Here is our local, out-dated (pre-5.6) version:


sub - declare a subroutine, possibly anonymously



sub BLOCK

sub NAME

sub NAME BLOCK



This is subroutine definition, not a real function per se. With just a NAME (and possibly prototypes), it's just a forward declaration. Without a NAME, it's an anonymous function declaration, and does actually return a value: the CODE ref of the closure you just created. See the perlsub manpage and the perlref manpage for details.

[talexb]: Wow, what hilariously bad form.
[SuicideJunkie]: Just wait; someday soon, you'll be given a DB with unicode emojis in the column names.
[Corion]: marinersk: Well, I have done select statements like select sum(foo) as "Total Amount", ..., but to have a table like that makes me shudder
[Corion]: SuicideJunkie: :-D
[marinersk]: SuicideJunkie LOL
[choroba]: Woohoo! Fixed a test that hasn't run for 3 years.
[marinersk]: Corion Yes, sometimes whitespace in column headers is acceptable, but I still consider it be less than desireable if that query might get revectored for an ETL-esque process...
[marinersk]: choroba++
