语法

声明
Public Property EventChronicleRule As EventChronicleRule

public EventChronicleRule EventChronicleRule { get; set; }

public:
property EventChronicleRule^ EventChronicleRule {
    EventChronicleRule^ get ();
    void set (EventChronicleRule^ value);
}

/** @property */
public EventChronicleRule get_EventChronicleRule ()

/** @property */
public void set_EventChronicleRule (EventChronicleRule value)

public function get EventChronicleRule () : EventChronicleRule

public function set EventChronicleRule (value : EventChronicleRule)

属性值

The EventChronicleRule for the event class.

备注

If the event class has EventChronicles, you must define an EventChronicleRule. The chronicle rule contains the Transact-SQL queries that maintain the data in the event chronicle tables.

示例

The following examples show how to define an event chronicle rule and then assign it to an event class:

// Define the event chronicle rule
EventChronicleRule ec1Rule = 
    new EventChronicleRule(flightEvents, 
    "FlightEventChronicleRule");
ec1Rule.Action = "INSERT MyAppSchema.FlightEventChronicle " + 
    " (LeavingFrom, GoingTo, Price) " + 
    " SELECT LeavingFrom, GoingTo, Price " + 
    " FROM MyAppSchema.FlightEvents;";
ec1Rule.ActionTimeout = new TimeSpan(0, 1, 20);
flightEvents.EventChronicleRule = ec1Rule;

' Define the event chronicle rule
Dim ec1Rule As EventChronicleRule = _
    New EventChronicleRule(flightEvents, _
        "FlightEventChronicleRule")
ec1Rule.Action = _
    "INSERT MyAppSchema.FlightEventChronicle " + _
    " (LeavingFrom, GoingTo, Price) " + _
    " SELECT LeavingFrom, GoingTo, Price " + _
    " FROM MyAppSchema.FlightEvents;"
ec1Rule.ActionTimeout = New TimeSpan(0, 1, 20)
flightEvents.EventChronicleRule = ec1Rule
