备注
When you use a condition action, you must specify which view or table contains the event data. The fields from the view or table are used to build a new view for the event or scheduled rule. The condition action selects data from the event or scheduled rule view.
Typically, the InputName value is the name of an event view or event chronicle:
- If the condition action is in an event rule, the input is typically an event view, which has the same name as an event class.
- If the condition action is for a scheduled rule, the input is typically an event chronicle.
For more information about condition actions, see 定义条件操作.
示例
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>
