Use Updategrams with SAS Data Sets Data

In this article, you will create updategrams that can be executed by the CData BizTalk Adapter for SAS Data Sets. You will design a schema and use it as a template for generating insert, update, and delete updategrams.

Add the Adapter for SAS Data Sets to Your Project

Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. You will use the adapter to query SAS Data Sets for metadata about the table you want to modify.

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 CData BizTalk Adapter for SAS Data Sets from the list view.
4. In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the adapter.
5. When you click Next, the Schema Wizard is displayed.

Generate a Schema for an Updategram

Follow the steps below to create a schema in a BizTalk Server project in Visual Studio.

1. If you have not already done so, add the SAS Data Sets adapter to your project.
2. On the Connection String page of the Add Adapter wizard, enter authentication credentials and other connection properties, if they were not already configured in the send port or receive location. Below is a typical connection string: URI=C:/myfolder;

   Set the following connection properties to connect to your SAS DataSet files:

   Connecting to Local Files

   • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
   • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

   Connecting to Cloud-Hosted SAS DataSet Files

   While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

   Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

   See the "BizTalk Configuration" chapter in the help documentation for more information on the required connection properties.

3. On the Schema Information page, click Send Port in the General Options section. Select Updategram from the CommandType menu. If you are using the adapter in a solicit-response send port, disable the One-Way option.

4. On the next page, Statement Information, select the type of the updategram: Insert, Update, or Delete. Select the Table name and the columns you want to include in the schema. If you want to update or delete, the Id column is required.

   Note: When you create the updategram, you are limited to modifying the columns you include in the schema.

5. Click Next to view a summary of the schema and finish the wizard to create the schema. The resulting .xsd file is added to your project.

Generate Insert, Update, and Delete Instance Messages

After you create the updategram schema, you can use the .xsd file to generate the updategram: Right-click the .xsd file and select Generate Instance. You can also use this file as a template to manually create updategrams. Below are example generated updategram instances for inserts, updates, and deletes:

Insert

An example of INSERT is below. In this instance, there is only an after block, which specifies how the data will change.

Update

An example of UPDATE is below. In this instance, there is both a before block (how the data currently exists in the table) and an after block (how the data will change).

Delete

An example for DELETE is below. The after block will be empty to show that it is removing the item.
