NAME

Class::DBI::Plugin::AbstractCount - get COUNT(*) results with abstract SQL

SYNOPSIS

   use base 'Class::DBI';
   use Class::DBI::Plugin::AbstractCount;
   
   my $count = Music::Vinyl->count_search_where(
     { artist   => 'Frank Zappa'
     , title    => { like    => '%Shut Up 'n Play Yer Guitar%' }
     , released => { between => [ 1980, 1982 ] }
     });

DESCRIPTION

This Class::DBI plugin combines the functionality from Class::DBI::Plugin::CountSearch (counting objects without having to use an array or an iterator), and Class::DBI::AbstractSearch, which allows complex where-clauses a la SQL::Abstract.

METHODS

count_search_where

Takes a hashref with the abstract where-clause. An additional attribute hashref can be passed to influence the default behaviour: arrayrefs are OR'ed, hashrefs are AND'ed.

TODO

More tests, more doc.
