Overview

Here is an overview of the steps:

  1. Configure the DSN for BigCommerce data in the CData ODBC Driver for BigCommerce with the necessary connection properties.
  2. Set up the ODBC connection in Lazarus by configuring the TSQLConnector, TSQLQuery, TDataSource, and TDBGrid components with the required details.
  3. Test the connection to BigCommerce data by writing sample code on the Main form.
  4. Compile and run the application to verify the successful integration and display of live BigCommerce data.

Prerequisites

Before starting, ensure you have the following:

  • Lazarus IDE (version 3.4 recommended). Download from here.
  • CData ODBC Driver for BigCommerce. Download and try the latest version from here.


Configure the BigCommerce DSN Using the CData ODBC Driver

To start, configure the DSN (Data Source Name) for BigCommerce data in your system using the CData ODBC Driver for BigCommerce. Download and install a 30-day free trial with all the features from here.

Once installed, launch the ODBC Data Source Administrator:

  • On Windows: Search for ODBC Data Source Administrator in the Start menu and open the application.
  • On Mac: Open Applications, go to Utilities, and select ODBC Manager.
  • On Linux: Use the command line to launch ODBC Data Source Administrator or use unixODBC if installed.

Once launched, double-click on the CData BigCommerce data Source and enter the required values to establish a connection:

BigCommerce authentication is based on the standard OAuth flow. To authenticate, you must initially create an app via the Big Commerce developer platform where you can obtain an OAuthClientId, OAuthClientSecret, and CallbackURL. These three parameters will be set as connection properties to your driver.

Additionally, in order to connect to your BigCommerce Store, you will need your StoreId. To find your Store Id please follow these steps:

  1. Log in to your BigCommerce account.
  2. From the Home Page, select Advanced Settings > API Accounts.
  3. Click Create API Account.
  4. A text box named API Path will appear on your screen.
  5. Inside you can see a URL of the following structure: https://api.bigcommerce.com/stores/{Store Id}/v3.
  6. As demonstrated above, your Store Id will be between the 'stores/' and '/v3' path paramters.
  7. Once you have retrieved your Store Id you can either click Cancel or proceed in creating an API Account in case you do not have one already.

Create a New GUI Project

  1. Launch the Lazarus IDE.
  2. Navigate to File > New > Application to create a new GUI project with a Main form.

Add Required Connection Components to the Form

  1. Go to View > Component > Palette and check the Keep open at the bottom-left to keep the Components window persistently open.
  2. Search for the following components and add them to the Main form Form1 by clicking on Use at the bottom right.
    1. TSQLConnector
    2. TSQLTransaction
    3. TSQLQuery
    4. TDataSource
    5. TDBGrid


Configure the TSQLConnector Component

The TSQLConnector component in Lazarus Pascal IDE facilitates connections between your application and various databases or database APIs. Here's how to configure it:

  1. Select the TSQLConnector component on the Main form.
  2. Open the Object Inspector if it's not already open by going to View > Object Inspector
  3. In the Object Inspector on the left, set the following properties under the Properties section:
    Property Value
    Connected True
    Driver ODBC
    DatabaseName Your DSN name (e.g., CData BigCommerce Source)
    UserName Your database username
    Password Your database password
    HostName BigCommerce URL or localhost for local databases
    LoginPrompt False
    Transaction Select your TSQLTransaction component

If your credentials require a security token, follow these steps:

  1. Double-click the Main Form in the Lazarus Pascal IDE to open the code editor.
  2. Locate the procedure TForm1.FormCreate(Sender: TObject); section.
  3. Paste the following code below the begin keyword. Replace 'your_security_token' with your actual security token: SQLConnector1.Params.Values ['Password'] := SQLConnector1.Params.Values ['Password'] + 'your_security_token';



Configure the TSQLQuery Component

The TSQLQuery component in Lazarus Pascal IDE receives SQL code for queries and retrieves data from a database, simplifying data manipulation. Configure using the following info:

  1. Select the TSQLQuery component in the Main form.
  2. Set the following properties in the Object Inspector under the Properties section:
    Property Value
    Active True
    DataBase Select the name of your TSQLConnector component
    SQL (Click 3 dots) Your query (e.g., SELECT * FROM Customers)
    Transaction Your TSQLTransaction component




Configure the TDataSource, TDBGrid, TSQLTransaction Components

The TDataSource component in Lazarus Pascal IDE bridges a dataset (e.g., TSQLQuery) with data-aware controls like TDBGrid, allowing data to be displayed and manipulated. The TDBGrid presents the data in a tabular format, while the TSQLTransaction ensures database operations maintain data integrity by executing within a transaction. Here's how to configure all three components:

  1. Select the TDataSource component and set its DataSet property to the name of your TSQLQuery component.
  2. Select the TDBGrid component and set its DataSource property to your TDataSource component.
  3. Select the TSQLTransaction component. Set the following properties:
    1. Active: True
    2. Database: The name of your TSQLConnector component


Add Code to Test the Connection

To successfully test the connection, use the following code:

  1. Double-click on the Main Form to open up the Source Editor.
  2. Add the following code under the begin keyword and before the end. keyword.
procedure TForm1.FormCreate(Sender: TObject); begin // Code for your Security Token SQLConnector1.Params.Values ['Password'] := SQLConnector1.Params.Values ['Password'] + 'your_security_token'; try SQLConnector1.Open; ShowMessage('Connection successful!'); except on E: Exception do ShowMessage('Error: ' + E.Message); end; try SQLQuery1.Open; if SQLQuery1.IsEmpty then ShowMessage('No data found.') else ShowMessage('Data loaded successfully.'); except on E: Exception do ShowMessage('Error: ' + E.Message); end; end; end.

Compile and Run the Application

Save your project. Go to Run > Compile, then Run, or use the shortcut F9 to execute your application.



Next Steps: Play with the Data

Now that your data is successfully imported into Lazarus, here are some ideas to explore its full potential:

  • Enhance Your TDBGrid: Customize your TDBGrid to enable sorting, editing, or highlighting specific rows.
  • Visualize Your Data: Use components like TChart to create graphs and charts for intuitive data representation.
  • Filter and Search: Use components like TDBFilter or implement custom filtering logic to allow users to quickly focus on relevant data. Add a TEdit component for user input and link it to your filtering functionality.
  • Export Your Data: Utilize TSVExport or TFileStream components to save your data in formats like CSV or Excel for sharing or integration into other systems.
  • Perform Calculations: Use TFPCustomDataSet or your dataset's built-in features to calculate totals, averages, or other metrics. Display results in a TLabel or add them to your TDBGrid.
  • Create Forms and Reports: Design interactive forms using TForm and TDBEdit for user interaction. For reports, integrate components like RLReport or FastReport to generate and print professional-quality reports.

Take your data-driven application to the next level with these enhancements!
