# TrackerSparqlConnection

TrackerSparqlConnection is an object that represents a connection to a SPARQL triple store. This store may be local and private (see tracker_sparql_connection_new), or it may be a remote connection to a public endpoint (See tracker_sparql_connection_bus_new and tracker_sparql_connection_remote_new).

A TrackerSparqlConnection is private to the calling process, it can be exposed publicly via a TrackerEndpoint, see tracker_endpoint_dbus_new.

Updates on a connection are performed via the tracker_sparql_connection_update family of calls. tracker_sparql_connection_update_array may be used for batched updates. All functions have asynchronous variants.

Queries on a connection are performed via tracker_sparql_connection_query and tracker_sparql_connection_query_statement. The first call receives a query string and returns a TrackerSparqlCursor to iterate the results. The second call returns a TrackerSparqlStatement object that may be reused for repeatable queries with variable parameters. tracker_sparql_statement_execute will returns a TrackerSparqlCursor.

Depending on the ontology definition, TrackerSparqlConnection may emit notifications whenever changes happen in the stored data. These notifications can be processed via a TrackerNotifier obtained with tracker_sparql_connection_create_notifier.

After use, a TrackerSparqlConnection should be closed. See tracker_sparql_connection_close and tracker_sparql_connection_close_async.

A TrackerSparqlConnection may be used from multiple threads, asynchronous database updates are executed sequentially on arrival order, asynchronous queries are executed in a thread pool.

    tracker_sparql_connection_new (TrackerSparqlConnectionFlags flags,
                                   GFile * store,

                                   GError ** error)

Creates or opens a database.

This method should only be used for databases owned by the current process. To connect to databases managed by other processes, use tracker_sparql_connection_bus_new.

If store is NULL, the database will be created in memory.

The ontologies parameter must point to a location containing suitable `.ontology` files in Turtle format. These control the database schema that is used. You can use the default Nepomuk ontologies by calling tracker_sparql_get_ontology_nepomuk ().

If you open an existing database using a different ontology to the one it was created with, Tracker will attempt to migrate the existing data to the new schema. This may raise an error. In particular, not all migrations are possible without causing data loss and Tracker will refuse to delete data during a migration.

You can also pass NULL for ontologies to mean "use the ontologies that the database was created with". This will fail if the database doesn't already exist.

Parameters:

`flags` –

values from TrackerSparqlConnectionFlags

`store` ( [nullable]) –

the directory that contains the database as a GFile, or NULL

`ontology` ( [nullable]) –

the directory that contains the database schemas as a GFile, or NULL

`cancellable` ( [nullable]) –

a GCancellable, or NULL

`error` –

pointer to a GError

Returns ( [transfer: full]) –

a new TrackerSparqlConnection. Call g_object_unref on the object when no longer used.

#### tracker_sparql_connection_update_blank

    GVariant *
    tracker_sparql_connection_update_blank (TrackerSparqlConnection * connection,
                                            const gchar * sparql,
                                            GCancellable * cancellable,
                                            GError ** error)

Executes a SPARQL update and returns the URNs of the generated nodes, if any. The API call is completely synchronous, so it may block.

The sparql query should be built with TrackerResource, or its parts correctly escaped using tracker_sparql_escape_string, otherwise SPARQL injection is possible.

The format string of the `GVariant` is `aaa{ss}` (an array of an array of dictionaries). The first array represents each INSERT that may exist in the SPARQL string. The second array represents each new node for a given WHERE clause. The last array holds a string pair with the blank node name (e.g. `foo` for the blank node `_:foo`) and the URN that was generated for it. For most updates the first two outer arrays will only contain one item.

Parameters:

`connection` –

a TrackerSparqlConnection

`sparql` –

string containing the SPARQL update query

`cancellable` –

a GCancellable used to cancel the operation

`error` –

GError for error reporting.

Returns –

a GVariant with the generated URNs, which should be freed with g_variant_unref when no longer used.

#### Tracker.SparqlConnection.prototype.update_blank
