주의
When you use a condition action, you must specify which view or table contains the event data. This view or table is in a schema.
- If the input is the view named after the event class, the schema is the application schema. The application schema can be specified when defining the application database, or it can be the default value of dbo. For more information, see 응용 프로그램 데이터베이스 정의.
- If the input is an event chronicle, the schema is defined in the CREATE TABLE statement that creates the event chronicle. This is usually the same as the application schema. For more information, see 이벤트 클래스에 대한 기록 정의.
For more information about condition actions, see 조건 작업 정의.
예
The following example shows how to define a condition action. The query in the Transact-SQL expression selects data from the MyAppSchema.WeatherEventRule view, which contains data from the subscription class and from the MyAppSchema.WeatherEvents event view.
<ConditionAction>
<SqlLogin>[MyLowPrivLogin]</SqlLogin>
<SqlUser>[MyLowPrivUser]</SqlUser>
<InputName>WeatherEvents</InputName>
<InputSchema>MyAppSchema</InputSchema>
<SqlExpression>
INSERT INTO MyAppSchema.WeatherNotifications(SubscriberId,
DeviceName, SubscriberLocale, City, Forecast)
SELECT [Subscription.SubscriberId], [Subscription.DeviceName],
[Subscription.SubscriberLocale], [Input.City],
[Input.Forecast])
FROM MyAppSchema.WeatherEventRule;
</SqlExpression>
</ConditionAction>
