NAME

Class::DBI::Search::Count - return count of results rather than results

SYNOPSIS

        use base 'Class::DBI';

        __PACKAGE__->add_searcher(
                search_count => 'Class::DBI::Search::Count'
        );

        my $recent = CD->search_count(year => 2005);

This is equivalent to, but, as the counting is done at the database rather than in perl, faster than:

  my $recent = CD->search(year => 2005)->count;

DESCRIPTION

This is a simple search plugin for Class::DBI to return a count of results rather than the results themselves.

METHODS

add_searcher

        __PACKAGE__->add_searcher(
                method_name => 'Class::DBI::Search::Count'
        );

As with all Search plugins you can choose the method name for the search that it generates.

sql

We override the SQL to be our own COUNT(*) version

run_search

We override this to return our count rather than the search results.
