DBIx::Class::ResultSource::View - ResultSource object representing a view
package MyDB::Schema::Year2000CDs; use DBIx::Class::ResultSource::View; __PACKAGE__->load_components('Core'); __PACKAGE__->table_class('DBIx::Class::ResultSource::View'); __PACKAGE__->table('year2000cds'); __PACKAGE__->result_source_instance->is_virtual(1); __PACKAGE__->result_source_instance->view_definition( "SELECT cdid, artist, title FROM cd WHERE year ='2000'" );
View object that inherits from DBIx::Class::ResultSource
This class extends ResultSource to add basic view support.
A view has a "view_definition", which contains an SQL query. The query cannot have parameters. It may contain JOINs, sub selects and any other SQL your database supports.
View definition SQL is deployed to your database on "deploy" in DBIx::Class::Schema unless you set "is_virtual" to true.
Deploying the view does not translate it between different database syntaxes, so be careful what you write in your view SQL.
Virtual views ("is_virtual" true), are assumed to not exist in your database as a real view. The "view_definition" in this case replaces the view name in a FROM clause in a subselect.
$schema->resultset('Year2000CDs')->all(); SELECT cdid, artist, title FROM year2000cds me
$schema->resultset('Year2000CDs')->all(); SELECT cdid, artist, title FROM (SELECT cdid, artist, title FROM cd WHERE year ='2000') me
__PACKAGE__->result_source_instance->is_virtual(1);
Set to true for a virtual view, false or unset for a real database-based view.
__PACKAGE__->result_source_instance->view_definition( "SELECT cdid, artist, title FROM cd WHERE year ='2000'" );
An SQL query for your view. Will not be translated across database syntaxes.
Returns the FROM entry for the table (i.e. the view name) or the SQL as a subselect if this is a virtual view.
