Zoho Projects Icon Zoho Projects ODBC Driver

The Zoho Projects ODBC Driver is a powerful tool that allows you to connect with live data from Zoho Projects, directly from any applications that support ODBC connectivity.

Access Zoho Projects data like you would a database - read, write, and update Zoho Projects 0, etc. through a standard ODBC Driver interface.

Build a Simple VCL Application for Zoho Projects Data


How to build a simple VCL Application to view Zoho Projects data in RAD Studio using the CData ODBC Driver for Zoho Projects.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Zoho Projects, you gain access to live Zoho Projects data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Zoho Projects data. This article will walk through connecting to Zoho Projects and creating a simple VCL application with the Form Designer.

Create a Connection to Zoho Projects Data

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.

The connector uses OAuth to authenticate with Zoho Projects. CData Software has already registered an OAuth application with Zoho Project which is embedded and used to authenticate.

If you use the embedded credentials, set the InitiateOAuth connection property to "GETANDREFRESH".

If you would prefer to use your own custom OAuth app, see the Help documentation.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Zoho Projects data.

  1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Zoho Projects.

Create VCL Applications with Connectivity to Zoho Projects Data

Follow the procedure below to start executing queries to Zoho Projects data from a simple VCL application that displays the results of a query in a grid.

  1. Drop a TFDConnection component onto the form and set the following properties:

    • ConnectionDefName: Select the FireDAC connection to Zoho Projects data.
    • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

  2. Drop a TFDQuery component onto the form and set the properties below:

    • Connection: Set this property to the TFDConnection component, if this component is not already specified.

    • SQL: Click the button in the SQL property and enter a query. For example:

      SELECT Id, Name FROM Portals WHERE CrmPartner = 'true'
    • Active: Set this property to true.

  3. Drop a TDataSource component onto the form and set the following property:

    • DataSet: In the menu for this property, select the name of the TFDQuery component.

  4. Drop a TDBGrid control onto the form and set the following property:

    • DataSource: Select the name of the TDataSource.
  5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
