Execute Stored Procedures to FTP in BizTalk

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

Stored procedures implement FTP 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 FTP 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:

    RemoteHost=MyFTPServer;

    To connect to FTP or SFTP servers, specify at least RemoteHost and FileProtocol. Specify the port with RemotePort.

    Set User and Password to perform Basic authentication. Set SSHAuthMode to use SSH authentication. See the Getting Started section of the data provider help documentation for more information on authenticating via SSH.

    Set SSLMode and SSLServerCert to secure connections with SSL.

    The data provider lists the tables based on the available folders in your FTP server. Set the following connection properties to control the relational view of the file system:

    • RemotePath: Set this to the current working directory.
    • TableDepth: Set this to control the depth of folders to list as views.
    • FileRetrievalDepth: Set this to retrieve and list files recursively from the root table.

    Stored Procedures are available to download files, upload files, and send protocol commands. See the Data Model chapter of the FTP data provider documentation for more information.

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 FTP Adapter.
  2. If you have configured the CData FTP 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.
