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.
