Method

TrackerSparqlConnectionquery

Declaration [src]

TrackerSparqlCursor*
tracker_sparql_connection_query (
  TrackerSparqlConnection* connection,
  const gchar* sparql,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Executes a SPARQL query on connection.

This method is synchronous and will block until the query is executed. See tracker_sparql_connection_query_async() for an asynchronous variant.

If the query is partially built from user input or other untrusted sources, special care is required about possible SPARQL injection. In order to avoid it entirely, it is recommended to use TrackerSparqlStatement. The function tracker_sparql_escape_string() exists as a last resort, but its use is not recommended.

Parameters

`sparql`	`const gchar*`
	String containing the SPARQL query.
	The data is owned by the caller of the function.
	The string is a NUL terminated UTF-8 string.
`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 results.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
