Execute Stored Procedures to HPCC Systems in BizTalk

You can use stored procedures provided by the CData BizTalk Adapter for HPCC Systems to automate working with HPCC Systems data in BizTalk. Stored procedures implement actions available in the underlying API.

Stored procedures implement HPCC Systems 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 HPCC Systems 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:

    URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;

    To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

    Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

    Set Cluster to the target cluster.

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 HPCC Systems Adapter.
  2. If you have configured the CData HPCC Systems 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.
