1. From the docs of DBIx::Class::ResultSet:
    search_literal

    Arguments: $sql_fragment, @bind_values

    Return Value: $resultset (scalar context), @row_objs (list context)

    my @cds   = $cd_rs->search_literal('year = ? AND title = ?', qw/2001 R
+eload/);
my $newrs = $artist_rs->search_literal('name = ?', 'Metallica');

    [download]
    Pass a literal chunk of SQL to be added to the conditional part of the resultset query.
  2. DBIx::Class::Exception perhaps?
  3. You can make a resultset, stuff it into a variable and keep it around without executing it and when you need it you can add to this results extra conditions and such and execute it. Unless and until you ask for the data in the resultset it will not make a trip to the database so its costs is minimal.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
