Abstract Class::DBI's SQL with SQL::Abstract

 Class::DBI::AbstractSearch is a Class::DBI plugin to glue the
 SQL::Abstract module into Class::DBI.
 .
 Class::DBI provides a convenient abstraction layer to a database. It
 not only provides a simple database to object mapping layer, but can
 be used to implement several higher order database functions, at the
 application level, rather than at the database.
 .
 SQL::Abstract provides methods for generating abstract SQL from Perl
 data structures.
