Method

TrackerSparqlStatementexecute

Declaration [src]

TrackerSparqlCursor*
tracker_sparql_statement_execute (
  TrackerSparqlStatement* stmt,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Executes the SELECT or ASK SPARQL query with the currently bound values.

This function also works for DESCRIBE and CONSTRUCT queries that retrieve data from the triple store. These query forms that return RDF data are however more useful together with tracker_sparql_statement_serialize_async().

This function should only be called on TrackerSparqlStatement objects obtained through tracker_sparql_connection_query_statement() or SELECT/CONSTRUCT/DESCRIBE statements loaded through tracker_sparql_connection_load_statement_from_gresource(). An error will be raised if this method is called on a INSERT or DELETE SPARQL query.

Parameters

`cancellable`	`GCancellable*`
	Optional `GCancellable`
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`TrackerSparqlCursor`
	A `TrackerSparqlCursor` with the query results.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
