# RDF::Helper::RDFRedland::Query(3pm)

Perlish convenience extension for RDF::Redland::Query

## 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.
