Notes

An event class schema defines an event class table in the application database. Notification Services automatically adds ID columns to this definition when creating the database table.

Exemple

The following example shows a Schema element that creates two event fields: a 10-character stock symbol field, and a stock price field that accepts monetary data.

<Schema>
    <Field>
        <FieldName>StockSymbol</FieldName>
        <FieldType>char(10)</FieldType>
        <FieldTypeMods>NOT NULL</FieldTypeMods>
    </Field>
    <Field>
        <FieldName>StockPrice</FieldName>
        <FieldType>money</FieldType>
        <FieldTypeMods>NOT NULL DEFAULT 10</FieldTypeMods>
    </Field>
</Schema>
