属性值

A String of up to 100,000 characters that specifies the Transact-SQL statements to execute each time the event chronicle rule runs.

备注

The Transact-SQL statements should maintain the event chronicle. Often you will select data from the current event class and update the event chronicle as appropriate for your application.

The action can contain calls to stored procedures.

示例

The following example shows how to create an event chronicle rule that simply copies all events to a chronicle:

// 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
