## Description

Events occuring on a connection are each represented as a GdaConnectionEvent object. Each GdaConnection is responsible for keeping a list of past events; that list can be consulted using the `gda_connection_get_events()` function.

To avoid memory leaks, the list of connection events is cleared before each statement (or group of statements) is executed.

### gda_connection_event_get_event_type ()

    GdaConnectionEventType  gda_connection_event_get_event_type
                                                            (GdaConnectionEvent *event);

Get `event`'s severity (from a simple notice to a fatal event)

`event` : | a GdaConnectionEvent object
Returns : | the event type

### gda_connection_event_get_description ()

    const gchar *       gda_connection_event_get_description
                                                            (GdaConnectionEvent *event);

Get the description of the event. Note that is `event`'s type is GDA_CONNECTION_EVENT_COMMAND, the the dsecription is the SQL of the command.

`event` : | a GdaConnectionEvent.
Returns : | `event`'s description.

### gda_connection_event_get_code ()

    glong               gda_connection_event_get_code       (GdaConnectionEvent *event);

`event` : | a GdaConnectionEvent.
Returns : | `event`'s code (the code is specific to the provider being used)

### gda_connection_event_get_gda_code ()

    GdaConnectionEventCode  gda_connection_event_get_gda_code
                                                            (GdaConnectionEvent *event);

Retreive the code associated to `event`.

`event` : | a GdaConnectionEvent
Returns : | the GdaConnectionEventCode event's code

### gda_connection_event_get_source ()

    const gchar *       gda_connection_event_get_source     (GdaConnectionEvent *event);

`event` : | a GdaConnectionEvent.
Returns : | `event`'s source.

### gda_connection_event_get_sqlstate ()

    const gchar *       gda_connection_event_get_sqlstate   (GdaConnectionEvent *event);

Get the SQLSTATE value of `event`. Even though the SQLSTATE values are specified by ANSI SQL and ODBC, consult each DBMS for the possible values. However, the "00000" (success) value means that there is no error, and the "HY000" (general error) value means an error but no better error code available.

`event` : | a GdaConnectionEvent.
Returns : | `event`'s SQL state.
