public Query prepareQuery(QueryLanguage ql, String query) throws MalformedQueryException, RepositoryException Description copied from interface:RepositoryConnectionPrepares a query for evaluation on this repository (optional operation). In case the query contains relative URIs that need to be resolved against an external base URI, one should useRepositoryConnection.prepareQuery(QueryLanguage, String, String)instead.If you already know the type of query, using the more specific
RepositoryConnection.prepareTupleQuery(java.lang.String),RepositoryConnection.prepareGraphQuery(java.lang.String)orRepositoryConnection.prepareBooleanQuery(java.lang.String)is likely to be more efficient.- Specified by:
