Class::DBI::AbstractSearch(3pm) User Contributed Perl Documentation Class::DBI::AbstractSearch(3pm) 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 { '!=', 'outdated' }, ); my @misc = CD::Music-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 { '!=', 'outdated' } }, { order_by =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: o order_by Array reference of fields that will be used to order the results of your query. o 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. o limit Scalar value that will be used for LIMIT argument in a query. o 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' }); AUTHOR
