Remarks

When using a chronicle you should include one SqlStatement element that drops or renames the chronicle table if it already exists and one SqlStatement element that creates the chronicle table. If you do not drop or rename an existing chronicle table, you will receive an "object exists" error when you update the application. For an example, see SqlSchema Element for SubscriptionClass/Chronicles/Chronicle (ADF).

If you want to keep your subscription chronicle data when updating your application, you can comment out the CREATE TABLE statement in your application definition file (ADF) after you create the application.

Example

The following example shows a SqlStatement element that creates the subscription chronicle table StockSubscriptionChron.

<SqlStatement>
CREATE TABLE StockSubscriptionChron
(
SubscriberId bigint,
StockSymbol char(10),
StockPrice money
PRIMARY KEY (SubscriberId)
);
</SqlStatement>
