Sorting within the SQL statement will be the most efficient, use the database sort order and respect values such as dates which in your output might look nice but are a nightmare to sort by the shell. Is there a reason you can't update the SQL? If the SQL is used by other processes, make a copy of it and change that instead.
Can you show us the SQL and some meaningful sample output from it? (in CODE tags, of course)
Thanks,
Robin

sql::translator::parser::dbix::class
SQL::Translator::Parser::DBIx::Class(3) User Contributed Perl Documentation SQL::Translator::Parser::DBIx::Class(3)
NAME
SQL::Translator::Parser::DBIx::Class - Create a SQL::Translator schema from a DBIx::Class::Schema instance
SYNOPSIS
## Via DBIx::Class
use MyApp::Schema;
my $schema = MyApp::Schema->connect("dbi:SQLite:something.db");
$schema->create_ddl_dir();
## or
$schema->deploy();
## Standalone
use MyApp::Schema;
use SQL::Translator;
my $schema = MyApp::Schema->connect;
my $trans = SQL::Translator->new (
parser => 'SQL::Translator::Parser::DBIx::Class',
parser_args => {
package => $schema,
add_fk_index => 0,
sources => [qw/
Artist
CD
/],
},
producer => 'SQLite',
) or die SQL::Translator->error;
my $out = $trans->translate() or die $trans->error;
DESCRIPTION
This class requires SQL::Translator installed to work.
"SQL::Translator::Parser::DBIx::Class" reads a DBIx::Class schema, interrogates the columns, and stuffs it all in an $sqlt_schema object.
Its primary use is in deploying database layouts described as a set of DBIx::Class classes, to a database. To do this, see "deploy" in
DBIx::Class::Schema.
This can also be achieved by having DBIx::Class export the schema as a set of SQL files ready for import into your database, or passed to
other machines that need to have your application installed but don't have SQL::Translator installed. To do this see "create_ddl_dir" in
DBIx::Class::Schema.
PARSER OPTIONS
add_fk_index
Create an index for each foreign key. Enabled by default, as having indexed foreign key columns is normally the sensible thing to do.
sources
Arguments: @class_names
Limit the amount of parsed sources by supplying an explicit list of source names.
