Connect to Zoho Recruit Data from PowerBuilder via ODBC

The CData ODBC Driver for Zoho Recruit can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to Zoho Recruit data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to Zoho Recruit as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To authenticate to ZohoRecruit, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

Using OAuth Authentication

First, you will need to register an OAuth application with ZohoRecruit. To do so, go to the Zoho Developer Console, add a new Client (Server-based application) and set a valid OAuth redirect URL. Your OAuth application will be assigned a client id and a client secret. Additionally, you will need to set the relevant Domain (.com, .eu, .in, .com.cn, or .jp), which defaults to .com.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to OAuth.
• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
• OAuthClientId: Set this to the client_id that is specified in your app settings.
• OAuthClientSecret: Set this to the client_secret that is specified in your app settings.
• CallbackURL: Set this to the Redirect URI that is specified in your app settings.
• Domain: Set this in ProfileSettings to your ZohoRecruit account domain (e.g. .com, .eu, .in, .com.cn, .jp).

Example connection string:

Profile=C:\profiles\ZohoRecruit.apip;ProfileSettings='Domain=.com';AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

Create a Profile for the ODBC Driver for Zoho Recruit

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Zoho Recruit. In the Database Painter, you can use wizards and the UI to work with Zoho Recruit data.

1. In PowerBuilder, click Tools -> Database Painter.
2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
3. On the Connection tab, enter a name for the profile and select the Zoho Recruit DSN in the Data Source menu.
4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Zoho Recruit Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Zoho Recruit data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC"
SQLCA.DBParm = "ConnectString='DSN=CData API Source'"
CONNECT USING SQLCA;
dw_attachments.SetTransObject(SQLCA);
dw_attachments.Retrieve();
