Method

TrackerSparqlConnectionupdate

Declaration [src]

void
tracker_sparql_connection_update (
  TrackerSparqlConnection* connection,
  const gchar* sparql,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Executes a SPARQL update on connection.

This method is synchronous and will block until the update is finished. See tracker_sparql_connection_update_async() for an asynchronous variant.

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.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.
