 sparql_query(+Query, -Reply, +Options)

Where Query is either a SPARQL query text or a parsed query. Reply depends on the type of query:

SELECT	row(Col1, Col2, ....)
CONSTRUCT	rdf(S,P,O)
DESCRIBE	rdf(S,P,O)
ASK	Reply == true or failure of pred

Options are:

entailment(Entailment)

Specify the entailment module used. The default is controlled by the setting sparql:entailment.

base_uri(Base)

Specify the base IRI to use for parsing the query

type(-Type)

Returns one of select(-VarNames), construct, describe or ask.

ordered(-Bool)

True if query contains an ORDER BY clause

distinct(-Bool)

True if query contains a DISTINCT clause

 sparql_compile(+Query, -Compiled, +Options)

Performs the compilation pass of solving a SPARQL query. Splitting serves two purposes. The result of the compilation can be cached if desired and through Options we can get information about the parsed query.

 sparql_run(+Compiled, -Reply) is nondet

Runs a compiled SPARQL query, returning the result incrementally on backtracking. Provided there are no errors in the SPARQL implementation the only errors this can produce are resource-related errors.
