Represents a event chronicle maintenance query to run for each generator quantum in which an event batch arrives into the parent event class.

Namespace: Microsoft.SqlServer.Management.Nmo
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

Syntax

'Declaration
Public NotInheritable Class EventChronicleRule

public sealed class EventChronicleRule : NamedSmoObject

public ref class EventChronicleRule sealed : public NamedSmoObject

public final class EventChronicleRule extends NamedSmoObject

public final class EventChronicleRule extends NamedSmoObject

Remarks

Event chronicle rules maintain the data in event chronicle tables. Each event chronicle has a name, an action, and an action time-out, and a parent event class.

Example

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
