NAME
Class::DBI::AbstractSearch - Abstract Class::DBI's SQL with SQL::Abstract::Limit

SYNOPSIS
  package CD::Music;
  use Class::DBI::AbstractSearch;

  package main;
  my @music = CD::Music->search_where(
      artist => [ 'Ozzy', 'Kelly' ],
      status => { '!=', 'outdated' },
  );

  my @misc = CD::Music->search_where(
      { artist => [ 'Ozzy', 'Kelly' ],
        status => { '!=', 'outdated' } },
      { order_by      => "reldate DESC",
        limit_dialect => 'LimitOffset',
        limit         => 1
        offset        => 2 });

DESCRIPTION
Class::DBI::AbstractSearch is a Class::DBI plugin to glue SQL::Abstract::Limit into Class::DBI.

METHODS
Using this module adds following methods into your data class.

search_where
      $class->search_where(%where);

    Takes a hash to specify WHERE clause. See SQL::Abstract for hash options.

      $class->search_where(\%where,\%attrs);

    Takes hash reference to specify WHERE clause. See SQL::Abstract for hash options. Takes a hash reference to specify additional query attributes. Class::DBI::AbstractSearch uses these attributes:

    •   order_by

        Array reference of fields that will be used to order the results of your query.

    •   limit_dialect

        Scalar, DBI handle, object class, etc. that describes the syntax model for a LIMIT/OFFSET SQL clause. Please see SQL::Abstract::Limit for more information.

    •   limit

        Scalar value that will be used for LIMIT argument in a query.

    •   offset

        Scalar value that will be used for OFFSET argument in a query.

    Any other attributes are passed to the SQL::Abstract::Limit constructor, and can be used to control how queries are created. For example, to use 'AND' instead of 'OR' by default, use:

        $class->search_where(\%where, { logic => 'AND' });
