Import Sybase Data into Microsoft Power Query



The CData Connect Server offers standards-based Web service endpoints that allow a variety of applications to access Sybase data. In this article, you will use the OData format to import Sybase data into Microsoft Power Query.

The Connect Server enables you to use Web services to connect to and query Sybase data. This article details how to import an OData feed of Sybase data into Microsoft Power Query.

Connect to Sybase from Power Query

To work with live Sybase data in Microsoft Power Query, we need to connect to Sybase from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Sybase data.

Add a Connect Server User

Create a User to connect to Sybase from Microsoft Power Query through Connect Server.

  1. Click Users -> Add
  2. Configure a User
  3. Click Save Changes and make note of the Authtoken for the new user

Connect to Sybase from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open Connect Server and click Connections
  2. Select "Sybase" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Sybase.

    To connect to Sybase, specify the following connection properties:

    • Server: Set this to the name or network address of the Sybase database instance.
    • Database: Set this to the name of the Sybase database running on the specified Server.

    Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

    Sybase supports several methods for authentication including Password and Kerberos.

    Connect Using Password Authentication

    Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

    • User: Set this to the username of the authenticating Sybase user.
    • Password: Set this to the username of the authenticating Sybase user.

    Connect using LDAP Authentication

    To connect with LDAP authentication, you will need to configure Sybase server-side to use the LDAP authentication mechanism.

    After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

    Connect Using Kerberos Authentication

    To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos. See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

    You can find an example connection string below: Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Sybase OData Endpoints in Connect Server

After connecting to Sybase, create OData Endpoints for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the Sybase database
  3. Select the table(s) you wish to work with and click Next
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Connect to Sybase Data from Power Query

Follow the steps below to import tables that can be refreshed on demand:

  1. Configure the Connect Server to use a version of the OData protocol that is recognized by Power Query. In the Connect Server administration console, click Settings -> Server and change the value of the Default Version property to 3.0.
  2. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From OData Feed, and enter the OData URL:

    https://your-server:8032/api.rsc
  3. Next, define authentication credentials and set privacy levels. Select Basic authentication and enter the credentials for a user authorized to make requests. Specify the Username field and enter the user's authtoken in the Password field.

    To change the authentication scheme that Power Query will use, click Power Query -> Data Source Settings. Select the OData feed from the list and then click "Edit Permissions..." Select the privacy level from the menu.

  4. You can now access Sybase data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Edit to open the Query Editor. This will display the table data.
