org.openrdf.repository.RepositoryConnection.prepareTupleQuery()
Prepares a query that produces sets of value tuples. In case the query contains relative URIs that need to be resolved against an external base URI, one should use {@link #prepareTupleQuery(QueryLanguage,String,String)} instead. @param ql The query language in which the query is formulated. @param query The query string. @throws IllegalArgumentException If the supplied query is not a tuple query. @throws MalformedQueryException If the supplied query is malformed. @throws UnsupportedQueryLanguageException If the supplied query language is not supported.
