Hi,
I’m trying to create the export tool for construct queries (for a large amount of data, up to 100M triples).
isql-v exec="set blobs on; sparql define output-format \"TURTLE\" CONSTRUCT { ?a ?b ?c. } WHERE { ?a ?b ?c. FILTER(isLiteral(?c)) }" > $TTL_PATH;
Returns Error 22023: [Virtuoso Driver][Virtuoso Server]SR…: The result vector is too large.
Without output format “TURTLE” it works fine, but I have no quotes, language, datatype, angle brackets for URIs.
In general, I need TURTLE format, or some another format, or some another way, which works with a cursor
