NAME Mojo::DB::Results::Role::Struct - Database query results as structs SYNOPSIS use Mojo::SQLite; my $sqlite = Mojo::SQLite->new(...); my $results = $sqlite->db->query('SELECT * FROM "table" WHERE "foo" = ?', 42); my $struct = $results->with_roles('Mojo::DB::Results::Role::Struct')->structs->first; my $bar = $struct->bar; # dies unless column "bar" exists use Mojo::Pg; my $pg = Mojo::Pg->new(...)->with_roles('Mojo::DB::Role::ResultsRoles'); push @{$pg->results_roles}, 'Mojo::DB::Results::Role::Struct'; my $results = $pg->db->query('SELECT "foo", "bar" FROM "table"'); foreach my $row ($results->structs->each) { my $foo = $row->foo; my $bar = $row->baz; # dies } DESCRIPTION This role can be applied to a results object for Mojo::Pg or similar database APIs. It provides "struct" and "structs" methods which return Struct::Dumb records, providing read-only accessors only for the expected column names. Note that a column name that is not a valid identifier is trickier to access in this manner. my $row = $results->struct; my $col_name = 'foo.bar'; my $val = $row->$col_name; # or my $val = $row->${\'foo.bar'}; You can apply the role to a results object using "with_roles" in Mojo::Base, or apply it to all results objects created by a database manager using Mojo::DB::Role::ResultsRoles as shown in the synopsis. METHODS Mojo::DB::Results::Role::Struct composes the following methods. struct my $struct = $results->struct; Fetch next row from the statement handle with the result object's array method, and return it as a struct. structs my $collection = $results->structs; Fetch all rows from the statement handle with the result object's arrays method, and return them as a Mojo::Collection object containing structs.
