속성 값

A String that specifies the database user name Notification Services creates. Database user names typically, but are not required to, match their associated login name.

주의

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.

Notification Services creates the user account; it cannot exist before you create the application.

Make sure the database user, and its associated Microsoft SQL Server Login, which is named using the SqlLoginName property, has restricted permissions in the database. Also make sure the user and the associated SqlLogin are not likely to be removed from the server or the domain while the application is deployed, as this will cause application errors.

Notification Services grants the necessary permissions on Notification Services objects, but does not grant permissions on the input tables or views, nor does it grant permissions on any user-defined functions that are used by condition actions. You needs to grant these permissions when deploying the application. For more information about granting these permissions, see 조건 작업 정의.

예

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)
