Method

TrackerSparqlConnectionupdate_async

Declaration [src]

void
tracker_sparql_connection_update_async (
  TrackerSparqlConnection* connection,
  const gchar* sparql,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Executes asynchronously a SPARQL update.

It is recommented to consider the usage of TrackerBatch to cluster database updates. Frequent isolated SPARQL updates through this method will have a degraded performance in comparison.

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, or to build the SPARQL input through TrackerResource. 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 update 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.
`callback`	`GAsyncReadyCallback`
	User-defined Gio.AsyncReadyCallback to be called when the asynchronous operation is finished.
`user_data`	`gpointer`
	User-defined data to be passed to `callback`.
