How to set up a connection to Google Calendar using different authentication methods




To access Google Calendar data from your applications, you need to provide some connection parameters that specify how to authenticate to the service. CData FireDAC Components for Google Calendars support three types of authentication methods: user accounts (OAuth), service accounts (OAuthJWT), and GCP instance accounts.


User accounts (OAuth) are the most common way of authenticating to Google Calendar. This method allows you to access your own calendar data or any calendar data that has been shared with you. To use this method, you need to obtain an OAuth client ID and client secret from the Google API Console, and then authorize the application using a web browser.


Service accounts (OAuthJWT) are useful when you want to access calendar data on behalf of a user or a group of users without requiring their consent. This method allows you to access any calendar data that has been delegated to the service account by the owner or administrator. To use this method, you need to create a service account from the Google API Console, and then generate and download a JSON key file that contains the credentials.


GCP instance accounts are convenient when you want to access calendar data from a Google Cloud Platform (GCP) instance, such as a Compute Engine or App Engine instance. This method allows you to access any calendar data that has been granted to the GCP instance by the owner or administrator. To use this method, you need to enable the Google Calendar API for your GCP project, and then assign the appropriate roles and permissions to the GCP instance.


Depending on the authentication method you choose, you need to provide different connection parameters to the CData FireDAC Components for Google Calendars. The following table summarizes the required parameters for each method:



Authentication Method


Required Parameters


User accounts (OAuth)


OAuthClientId, OAuthClientSecret, CallbackURL, InitiateOAuth


Service accounts (OAuthJWT)


OAuthJWTCertType, OAuthJWTCert, OAuthJWTSubject, OAuthJWTIssuer


GCP instance accounts


GCPProjectID, GCPLocation, GCPInstanceName, GCPInstanceZone


You can find more details and examples on how to set up these parameters in the documentation.


How to use CData FireDAC Components for Google Calendars in Delphi or C++ Builder applications




Once you have installed and configured CData FireDAC Components for Google Calendars, you can start using them in your Delphi or C++ Builder applications. You can use the FireDAC Explorer to browse and query Google Calendar data, or use the FireDAC components in code and data controls to access and manipulate Google Calendar data.


How to use the FireDAC Explorer to browse and query Google Calendar data




The FireDAC Explorer is a graphical tool that allows you to explore and query data sources using FireDAC components. You can use it to test your connection to Google Calendar, view the available tables and views, execute SQL queries, and export data.


To use the FireDAC Explorer with CData FireDAC Components for Google Calendars, follow these steps:


  • Launch RAD Studio and open the FireDAC Explorer from the Tools menu.



  • In the FireDAC Explorer window, right-click on the Connections node and select Add New Connection.



  • In the Connection Editor dialog box, enter a name for your connection and select CData.GoogleCalendar as the driver.



  • In the Parameters tab, enter the connection parameters that correspond to your authentication method (see the previous section).



  • Click Test Connection to verify that you can connect to Google Calendar successfully.



  • Click OK to save your connection.



  • Expand your connection node in the FireDAC Explorer window and browse the tables and views that represent Google Calendar data.



  • To execute a SQL query, right-click on a table or view and select Query Data. You can also use the SQL Editor tab to write your own queries.



  • To export data, right-click on a table or view and select Export Data. You can choose from various formats such as CSV, XML, JSON, HTML, etc.



How to use the FireDAC components in code and data controls




You can also use CData FireDAC Components for Google Calendars in code and data controls in your Delphi or C++ Builder applications. You can use the TFDConnection component to establish a connection to Google Calendar, and then use other components such as TFDQuery, TFDTable, TFDCommand, TFDUpdateSQL, etc. to access and manipulate Google Calendar data.


To use CData FireDAC Components for Google Calendars in code and data controls, follow these steps:


  • Create a new VCL Forms Application project in RAD Studio.



  • Add a TFDConnection component to your form and set its DriverName property to CData.GoogleCalendar.



  • In the Object Inspector, click on Params and enter the connection parameters that correspond to your authentication method (see the previous section).



  • Add a TFDQuery component to your form and set its Connection property to your TFDConnection component.



  • In the Object Inspector, click on SQL and enter a SQL query that retrieves Google Calendar data. For example: SELECT * FROM Events WHERE CalendarId = 'primary'.



  • Add a TDataSource component to your form and set its DataSet property to your TFD Query component.



  • Add a TDBGrid component to your form and set its DataSource property to your TDataSource component.



  • Run your application and see the Google Calendar data displayed in the grid.



  • You can also use other FireDAC components and data controls to perform CRUD operations on Google Calendar data. For example, you can use a TFDUpdateSQL component to define the SQL statements for inserting, updating, and deleting data, and then link it to your TFDQuery component. You can also use a TDBNavigator component to provide a user interface for navigating and editing data.



How to perform CRUD operations on Google Calendar data




CData FireDAC Components for Google Calendars allow you to perform CRUD (create, read, update, and delete) operations on Google Calendar data using SQL statements or FireDAC methods. You can insert, update, and delete data from tables such as Calendars, Events, Attendees, etc. using the standard SQL syntax or the FireDAC ExecSQL, ApplyUpdates, and CommitUpdates methods.


For example, to insert a new event into the primary calendar, you can use the following SQL statement:


INSERT INTO Events (CalendarId, Summary, StartDate, EndDate) VALUES ('primary', 'My New Event', '2023-06-12T10:00:00', '2023-06-12T11:00:00')


To update an existing event, you can use the following SQL statement:


UPDATE Events SET Summary = 'My Updated Event' WHERE Id = '1234567890'


To delete an event, you can use the following SQL statement:


DELETE FROM Events WHERE Id = '1234567890'


You can execute these SQL statements using the TFDQuery or TFDCommand components in your code or data controls. Alternatively, you can use the FireDAC methods to perform CRUD operations without writing SQL statements. For example, to insert a new event using the FireDAC methods, you can use the following code:


var Event: TFDDatSRow; begin // Create a new row in the Events table Event := FDQuery1.Table.Rows.Add; // Set the values for the columns Event['CalendarId'] := 'primary'; Event['Summary'] := 'My New Event'; Event['StartDate'] := '2023-06-12T10:00:00'; Event['EndDate'] := '2023-06-12T11:00:00'; // Apply the changes to the database FDQuery1.ApplyUpdates; end;


You can find more details and examples on how to perform CRUD operations on Google Calendar data in the documentation.


How to use advanced features such as caching, batching, and metadata querying




CData FireDAC Components for Google Calendars also provide some advanced features that can enhance the performance and functionality of your applications. These features include caching, batching, and metadata querying.


Caching is a feature that allows you to store a copy of Google Calendar data locally and access it without making requests to the server. This can improve the speed and reliability of your applications, especially when working with large or frequently accessed data sets. You can enable caching by setting the CacheLocation and CacheProvider connection parameters. You can also control how the cache is updated by setting the AutoCache and CacheTolerance parameters.


Batching is a feature that allows you to execute multiple SQL statements in a single request to the server. This can reduce the network traffic and improve the performance of your applications. You can enable batching by setting the BatchSize connection parameter. You can also control how the batch is executed by setting the BatchExecuteMode parameter.


Metadata querying is a feature that allows you to retrieve information about the structure and properties of Google Calendar data. This can help you understand and explore the data source without writing SQL queries. You can query metadata by using special tables such as sys_catalogs, sys_schemas, sys_tables, sys_columns, etc. You can also query metadata by using FireDAC methods such as GetTableNames, GetFieldNames, GetKeyFieldNames, etc.


You can find more details and examples on how to use these advanced features in the documentation.
