Hinweise

Event chronicles are optional; use them only if you need to maintain event information outside of the event tables used by an event class. A common reason to use an event chronicle is to store and maintain event data for scheduled subscriptions.

Each EventChronicle must have one or more Transact-SQL statements specified using the SqlStatements property.

Beispiel

The following examples show how to define an event chronicle and add it to the collection of chronicles for an event class:

// Define a chronicle for the class
EventChronicle ec1 = 
    new EventChronicle(flightEvents, "FlightEventChonicle");
ec1.SqlStatements.Add(
    "CREATE TABLE MyAppSchema.FlightEventChronicle " + 
    " (LeavingFrom nvarchar(6), GoingTo nvarchar(6), " +  
    " Price float);");
ec1.SqlStatements.Add(
    "CREATE INDEX FlightEventChronicleIndex  " + 
    "ON MyAppSchema.FlightEventChronicle " + 
    "( LeavingFrom, GoingTo );");
flightEvents.EventChronicles.Add(ec1);

' Define a chronicle for the class.
Dim ec1 As EventChronicle = _
    New EventChronicle(flightEvents, "FlightEventChonicle")
ec1.SqlStatements.Add( _
    "CREATE TABLE MyAppSchema.FlightEventChronicle " + _
    " (LeavingFrom nvarchar(6), GoingTo nvarchar(6), " + _
    " Price float);")
ec1.SqlStatements.Add( _
    "CREATE INDEX FlightEventChronicleIndex " + _
    "ON MyAppSchema.FlightEventChronicle " + _
    "( LeavingFrom, GoingTo );")
flightEvents.EventChronicles.Add(ec1)
