Execute Stored Procedures to Amazon DynamoDB in BizTalk

Stored procedures implement Amazon DynamoDB actions that cannot be represented as SELECT, INSERT, UPDATE, and DELETE statements. This article shows how to generate a schema for a stored procedure. You can use the schema to execute the stored procedure from a send port.

Add the Adapter to Your Project

Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. The adapter will return metadata about the inputs of the stored procedure and its results. This metadata is needed to create the schema.

1. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
2. Select Add Adapter Metadata in the resulting dialog box.
3. In the resulting Add Adapter wizard, select the adapter from the list.
4. In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the Amazon DynamoDB Adapter.

5. On the Connection String page, enter authentication credentials and other connection properties if they were not already configured in the send port or the receive location.

   Below is a typical connection string:

   Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;

   The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

Generate the Schema

After you enter connection properties in the Add Adapter wizard, the Schema wizard is displayed.

1. On the next page, Schema Information, select the Send Port that you have configured to use the Amazon DynamoDB Adapter.
2. If you have configured the CData Amazon DynamoDB Adapter in a solicit-response send port, disable the One-Way option.
3. In the Command Type menu, select Stored Procedure.
4. Select the stored procedure from the menu and enter the values for the input parameters.
5. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
