DataBind Controls to Facebook Ads データ in C++Builder
DataBind to Facebook Ads のデータ in C++Builder with standard components and controls.
最終更新日：2023-06-12The CData ODBC Driver for Facebook Ads makes it easy to integrate connectivity to live Facebook Ads 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 Facebook Ads 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 Facebook Ads 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.
Facebook Ads 接続プロパティの取得・設定方法
ほとんどのテーブルで、アプリケーション認証と同様にユーザー認証を必要とします。Facebook Ads はユーザー認証にOAuth 標準を使用しています。Facebook への認証には、組み込み認証を使用してブラウザ経由で完結することもできますし、Facebook にアプリを登録することで独自のOAuthClientId、OAuthClientSecret、CallbackURL を取得することもできます。
の設定方法については、ヘルプドキュメントの「OAuth」セクションを参照してください。
任意で以下の項目を設定して、フィルタリングや集計を行うもできます。必要に応じてご利用ください。
- Target：Facebook データのテーブルのいくつかはターゲットでフィルタリングできます。例えば、動画のコメントを取得するにはターゲットに動画のID を指定します。このプロパティは、クエリ結果を指定されたターゲットに合致するレコードにフィルタリングします。Target カラムを使ってクエリ毎にこの制限をかけることができます。
- AggregateFormat：CData 製品は、いくつかのカラムを文字列集合として返します。例えば、エンティティのいいねデータは集計されて返されます。デフォルトでは、CData 製品はJSON で集計カラムを返します。集計をXML で返すことも可能です。
- RetryLevel：このプロパティを使用して、特定の広告インサイトのクエリとエラーに対するクエリの自動再試行を制御します。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Facebook Ads.
- 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 Facebook Ads.
Create VCL Applications with Connectivity to Facebook Ads データ
Follow the procedure below to start querying Facebook Ads 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 Facebook Ads.
- 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 AccountId, Name FROM AdAccounts WHERE Name = 'Acct Name'- 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 Facebook Ads with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to Facebook Ads のデータ. This section provides facebookadsspecific examples of executing queries with the TFQuery component.
Connect to Facebook Ads 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 Facebook Ads ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to Facebook Ads 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 AdAccounts where name = :Name";
FDQuery1->ParamByName("name")->AsString = "Acct Name";
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 AdAccounts where name = :Name";
FDQuery1.ParamByName("name")->AsString = "Acct Name";
FDQuery1->Open();
