DataBind to SurveyMonkey のデータ in C++Builder with standard components and controls.
最終更新日:2023-06-12The CData ODBC Driver for SurveyMonkey makes it easy to integrate connectivity to live SurveyMonkey 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 SurveyMonkey 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 SurveyMonkey 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.
SurveyMonkey はOAuth 2 認証標準を利用しています。SurveyMonkey がアンケートの回答を読むためにこれを必要とすることを考えると、アンケートを読むアカウントには有料プランのサブスクリプションが必要です。
SurveyMonkey への接続に使用できる認証方法は2つあります。
- プライベートoauth アプリケーションを登録するときに、パーソナルアクセストークンを使用します。
- パブリックoauth アプリケーションを登録するときに、OAuth を使用します。
パーソナルアクセストークンの使用
個人用トークンを使用して、自分のデータをテストし、アクセスします。個人用トークンを取得するには、ヘルプの「Creating a Custom OAuth App」の手順に従って、次の接続プロパティを設定します。
- OAuthAccessToken:アプリケーション設定で生成されたAccessToken に設定。
- InitiateOAuth:OFF に設定。
OAuth の使用
CData 製品はすでにSurveyMonkey にOAuth アプリケーションとして登録されています。そのため、デフォルトでは、自動的に埋め込みクレデンシャルを使用して接続します。
独自のカスタムOAuth アプリを使用したい場合は、ヘルプのCustom Credentials 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 SurveyMonkey.
- 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 SurveyMonkey.

Create VCL Applications with Connectivity to SurveyMonkey データ
Follow the procedure below to start querying SurveyMonkey 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 SurveyMonkey.
- 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 RespondentId, ChoiceId FROM MySurvey_Responses
- 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 SurveyMonkey with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to SurveyMonkey のデータ. This section provides surveymonkeyspecific examples of executing queries with the TFQuery component.
Connect to SurveyMonkey 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 SurveyMonkey ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to SurveyMonkey 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 MySurvey_Responses where choicetext = :ChoiceText";
FDQuery1->ParamByName("choicetext")->AsString = "blue";
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 MySurvey_Responses where choicetext = :ChoiceText";
FDQuery1.ParamByName("choicetext")->AsString = "blue";
FDQuery1->Open();
