RDF::Helper::RDFRedland::Query(3pm) User Contributed Perl Documentation RDF::Helper::RDFRedland::Query(3pm) NAME
RDF::Helper::RDFReland::Query - Perlish convenience extension for RDF::Redland::Query SYNOPSIS
my $model = RDF::Redland::Model->new( RDF::Redland::Storage->new( %storage_options ) ); my $rdf = RDF::Helper->new( Namespaces => \%namespaces, BaseURI => 'http://domain/NS/2004/09/03-url#' ); my $q_obj = $rdf->new_query( $sparql_text, 'sparql' ); # arrays while ( my $row = $q_obj->selectrow_arrayref ) { # $row is an array reference. } # hashes while ( my $row = $q_obj->selectrow_hashref ) { # $row is a hash reference. } DESCRIPTION
RDF::Helper::RDFRedland::Query is the object retuned from RDF::Helper's new_query() method when using RDF::Redland as the base interface class. This object provides everything that an instance of RDF::Redland::Query offers, plus the convenience methods detailed below. METHODS
selectrow_arrayref Returns each row as a Perl array references. The order of the array's indices will correspond to the order of the variable bindings in the query. selectrow_hashref Returns each row as a Perl hash references. The keys in the hash will have the same names as the variable bindings in the query. AUTHOR
