Eigenschaftswert

A String that specifies the name of a SQL Server login.

Hinweise

All SubscriptionConditionEventRule rules execute in the context of a database user that you specify. Using a low-privileged user minimizes the security threat in case anyone compromises your subscription management interface and inserts conditions that attempt to access other tables or perform other actions.

You specify the database user using the SqlUserName property. You specify the login account that is associated with the user using SqlLoginName property. The login must exist before Notification Services creates the application. If the login does not exist, Notification Services fails when attempting to create the application and rolls back the instance creation or instance update. Make sure the login will continue to exist while the application is deployed.

The login can be either a Windows Authentication login or a SQL Server Authentication login. The login is used within the Database Engine instance to run rule logic.

Beispiel

The following example shows how to define a condition-based, event-driven subscription rule and add it to a subscription class:

// Add a rule to generate condition-based, event notifications
SubscriptionConditionEventRule flightConditionEventRule = 
    new SubscriptionConditionEventRule(
    flightSubscriptions, "FlightConditionEventRule");
flightConditionEventRule.EventClassName = "FlightEvents";
flightConditionEventRule.ActionTimeout = new TimeSpan(0, 2, 0);
flightConditionEventRule.SqlLoginName = "MyLowPrivLogin";
flightConditionEventRule.SqlUserName = "MyLowPrivUser";
flightConditionEventRule.InputTypeName = "FlightEvents";
flightConditionEventRule.InputTypeSchema = "MyAppSchema";
flightConditionEventRule.SqlExpression =
    "INSERT INTO MyAppSchema.FlightNotifications (SubscriberId, " +
    "DeviceName, SubscriberLocale, LeavingFrom, GoingTo, Price) " +
    "SELECT [Subscription.SubscriberId], [Subscription.DeviceName], " +
    "[Subscription.SubscriberLocale], " +
    "[Input.LeavingFrom], [Input.GoingTo], [Input.Price] " +
    "FROM MyAppSchema.FlightConditionEventRule;";
flightSubscriptions.SubscriptionConditionEventRules.Add(
    flightConditionEventRule);
' Add a rule to generate condition-based, event notifications
Dim flightConditionEventRule As _
    SubscriptionConditionEventRule = _
    New SubscriptionConditionEventRule( _
    flightSubscriptions, "FlightConditionEventRule")
flightConditionEventRule.EventClassName = "FlightEvents"
flightConditionEventRule.ActionTimeout = New TimeSpan(0, 2, 0)
flightConditionEventRule.SqlLoginName = "MyLowPrivLogin"
flightConditionEventRule.SqlUserName = "MyLowPrivUser"
flightConditionEventRule.InputTypeName = "FlightEvents"
flightConditionEventRule.InputTypeSchema = "MyAppSchema"
flightConditionEventRule.SqlExpression = _
 "INSERT INTO MyAppSchema.FlightNotifications " + _
 "(SubscriberId, DeviceName, SubscriberLocale, LeavingFrom, " + _
 "GoingTo, Price) SELECT [Subscription.SubscriberId], " + _
 "[Subscription.DeviceName], [Subscription.SubscriberLocale], " + _
 "[Input.LeavingFrom], [Input.GoingTo], [Input.Price] " + _
 "FROM MyAppSchema.FlightConditionEventRule;"
flightSubscriptions.SubscriptionConditionEventRules.Add( _
    flightConditionEventRule)
