备注

The SubscriptionScheduledRule class represents a rule that uses simple parameter-based Transact-SQL queries to generate notifications for scheduled subscriptions.

Each SubscriptionScheduledRule object must specify an action, which is a Transact-SQL query that does the work of the rule. A subscription class can have multiple SubscriptionScheduledRule objects, and can also have SubscriptionConditionScheduledRule, SubscriptionEventRule, and SubscriptionConditionEventRule objects.

SubscriptionScheduledRule objects are associated with a subscription class through the SubscriptionScheduledRules property.

示例

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

// Add a rule to generate basic scheduled notifications
SubscriptionScheduledRule flightScheduledRule = 
    new SubscriptionScheduledRule(
    flightSubscriptions, "FlightScheduledRule");
flightScheduledRule.Action = "INSERT INTO FlightNotifications " + 
    "(SubscriberId, DeviceName, SubscriberLocale, " +
    " LeavingFrom, GoingTo, Price) " + 
    " SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " +
    " EC.LeavingFrom, EC.GoingTo, EC.Price " + 
    " FROM FlightEventChronicle EC, FlightSubscriptions S " +
    " WHERE EC.LeavingFrom = S.LeavingFrom " + 
    " AND EC.GoingTo = S.GoingTo " +
    " AND EC.Price < S.Price";
flightScheduledRule.ActionTimeout = new TimeSpan(0, 0, 30);
flightSubscriptions.SubscriptionScheduledRules.Add(
    flightScheduledRule);

' Add a rule to generate basic scheduled notifications
Dim flightScheduledRule As SubscriptionScheduledRule = _
    New SubscriptionScheduledRule(flightSubscriptions, _
        "FlightScheduledRule")
flightScheduledRule.Action = _
    "INSERT INTO FlightNotifications " + _
    "(SubscriberId, DeviceName, SubscriberLocale, " + _
    "LeavingFrom, GoingTo, Price) " + _
    "SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale,  " + _
    "EC.LeavingFrom, EC.GoingTo, EC.Price " + _
    "FROM FlightEventChronicle EC, FlightSubscriptions S " + _
    "WHERE EC.LeavingFrom = S.LeavingFrom " + _
    "AND EC.GoingTo = S.GoingTo " + _
    "AND EC.Price < S.Price"
flightScheduledRule.ActionTimeout = New TimeSpan(0, 0, 30)
flightSubscriptions.SubscriptionScheduledRules.Add( _
    flightScheduledRule)
