DataBind Controls to Google Analytics データ in C++Builder
DataBind to Google Analytics のデータ in C++Builder with standard components and controls.
最終更新日：2023-06-12The CData ODBC Driver for Google Analytics makes it easy to integrate connectivity to live Google Analytics のデータ with standard data access components in C++Builder. This article shows how to create a simple visual component library (VCL) application in C++Builder that connects to Google Analytics のデータ, executes queries, and displays the results in a grid. An additional section shows how to use FireDAC components to execute commands from code.
Create a Connection to Google Analytics データ
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.
OAuth 認証標準を使用してGoogle Analytics に接続します。ユーザーアカウントまたはサービスアカウントで認証できます。組織全体のアクセススコープをCData 製品に許可するには、サービスアカウントが必要です。下記で説明するとおり、CData 製品はこれらの認証フローをサポートします。
ユーザー資格情報の接続プロパティを設定せずに接続できます。次を設定して、接続してください。 Profile：接続するGoogle アナリティクスのプロファイル、またはビューに設定。この値はProfiles テーブルから取得できます。指定しない場合は、初めに返されたプロファイルが使われます。接続すると、CData 製品はデフォルトブラウザでOAuth エンドポイントを開きます。ログインして、アプリケーションにアクセス許可を与えます。CData 製品がOAuth プロセスを完了します。他のOAuth 認証フローについては、ヘルプドキュメントの「OAuth 認証の使用」を参照してください。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Google Analytics.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Google Analytics.
Create VCL Applications with Connectivity to Google Analytics データ
Follow the procedure below to start querying Google Analytics のデータ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Google Analytics.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
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 Browser, Sessions FROM Traffic- Active: Set this property to true.
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.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.
Execute Commands to Google Analytics with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to Google Analytics のデータ. This section provides ganalyticsspecific examples of executing queries with the TFQuery component.
Connect to Google Analytics データ
To connect to the data source, set the Connected property of the TFDConnection component to true. You can set the same properties from code:
FDConnection1->ConnectionDefName = "CData Google Analytics ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to Google Analytics のデータ, set the Connection property of the component. When a TFDQuery component is added at design time, its Connection property is automatically set to point to a TFDConnection on the form, as in the application above.
Create Parameterized Queries
To create a parameterized query, use the following syntax below:
FDQuery1->SQL->Text = "select * from Traffic where transactions = :Transactions";
FDQuery1->ParamByName("transactions")->AsString = "0";
query->Open();
The example above binds a string-type input parameter by name and then opens the dataset that results.
Prepare the Statement
Preparing statements is costly in system resources and time. The connection must be active and open while a statement is prepared. By default, FireDAC prepares the query to avoid recompiling the same query over and over. To disable statement preparation, set ResourceOptions.DirectExecute to True; for example, when you need to execute a query only once.
Execute a Query
To execute a query that returns a result set, such as a select query, use the Open method. The Open method executes the query, returns the result set, and opens it. The Open method will return an error if the query does not produce a result set.
FDQuery1->SQL->Text := "select * from Traffic where transactions = :Transactions";
FDQuery1.ParamByName("transactions")->AsString = "0";
FDQuery1->Open();
