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 " + _
