Example

The following examples show how to define a subscription chronicle and add it to a subscription class:

// Define a chronicle for the subscription class
SubscriptionChronicle sc1 = new SubscriptionChronicle(
    flightSubscriptions, "FlightSubChronicle");
sc1.SqlStatements.Add(
    "CREATE TABLE MyAppSchema.FlightSubChronicle " + 
    " (SubscriptionId bigint, LeavingFrom nvarchar(6), " + 
    "  GoingTo nvarchar(6), Price float);");
sc1.SqlStatements.Add(
    "CREATE INDEX FlightSubChronicleIndex  " +
    " ON MyAppSchema.FlightSubChronicle " +
    " ( LeavingFrom, GoingTo );");
flightSubscriptions.SubscriptionChronicles.Add(sc1);

' Define a chronicle for the subscription class
Dim sc1 As SubscriptionChronicle = New SubscriptionChronicle( _
    flightSubscriptions, "FlightSubChronicle")
sc1.SqlStatements.Add( _
    "CREATE TABLE MyAppSchema.FlightSubChronicle " + _
    "(SubscriptionId bigint, LeavingFrom nvarchar(6), " + _
    "GoingTo nvarchar(6), Price float);")
sc1.SqlStatements.Add( _
    "CREATE INDEX FlightSubChronicleIndex  " + _
    "ON MyAppSchema.FlightSubChronicle " + _
    "( LeavingFrom, GoingTo );")
flightSubscriptions.SubscriptionChronicles.Add(sc1)
