Hinweise

A notification class schema defines the schema of the notification data in the application database. SQL Server 2005 Notification Services uses the fields defined in the schema to construct a table to store the notification data. Notification Services adds columns to the table for identifying and tracking notifications and to identify the subscriber, device, and locale.

Beispiel

The following example shows a Schema element that defines three notification fields: a 10-character stock symbol field, and a stock value field that accepts monetary data, and a computed field that determines how much the stock price has changed.

<Schema>
    <Fields>
        <Field>
            <FieldName>StockSymbol</FieldName>
            <FieldType>char(10)</FieldType>
            <DigestGrouping>true<DigestGrouping>
        </Field>
        <Field>
            <FieldName>StockPrice</FieldName>
            <FieldType>money</FieldType>
        </Field>
    </Fields>
    <ComputedFields>
        <ComputedField>
            <FieldName>StockPriceChar</FieldName>
            <SqlExpression>CONVERT(NVARCHAR(10), StockPrice, 1)
