DataBind to Workday のデータ in C++Builder with standard components and controls.
最終更新日:2023-06-12The CData ODBC Driver for Workday makes it easy to integrate connectivity to live Workday 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 Workday 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 Workday 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.
Workday 接続プロパティの取得・設定方法
ここでは、4つのWorkday API の接続パラメータを設定する方法、およびTenant とBaseURL を取得する方法について説明します。必要なAPI のパラメータが設定され、カスタムOAuth および / またはAzure AD API クライアントを作成したら、接続の準備は完了です。
接続の前提条件
API / 前提条件 / 接続パラメータ
WQL / WQL サービスを有効化(下記参照) / ConnectionType: WQL
Reports as a Service / カタログレポートの設定(ヘルプドキュメントの「データアクセスのファインチューニング」参照) / ConnectionType:
Reports
REST / 自動で有効化 / ConnectionType: REST
SOAP / 自動で有効化 / ヘルプドキュメントのWorkday SOAP API への認証を参照
BaseURL およびTenant の取得
BaseURL およびTenant プロパティを取得するため、Workday にログインしてView API Clients を検索します。 この画面では、Workday はBaseURL とTenant の両方を含むURL であるWorkday REST API Endpoint を表示します。
REST API Endpoint のフォーマットは、
https://domain.com/subdirectories/mycompany です。ここで、
- https://domain.com/subdirectories/ はBaseURL です。
- mycompany(URL の最後のスラッシュの後の部分)はTenant です。
例えば、REST API エンドポイントがhttps://wd3-impl-services1.workday.com/ccx/api/v1/mycompany の場合、 BaseURL はhttps://wd3-impl-services1.workday.com であり、Tenant はmycompany です。
WQL サービスを有効化
Workday WQL API を介して接続するには、はじめにWQL Service を有効にする必要があります。
- Workday を開きます。
- 検索バーにView Domain と入力します。
- プロンプトにWorkday Query Language と入力します。
- Allowed Security Group Types のいずれかに、接続するユーザーが含まれていることを確認します。
Workday への認証
Basic 認証以外のほとんどのWorkday 接続では、認証のためにOAuth ベースのカスタムAPI クライアントアプリケーションを作成する必要があります。これには、ユーザーがAzure AD 資格情報を介して接続するエンタープライズインストールも含まれます。 Workday への認証につての詳細は、ヘルプドキュメントの「Workday への認証」セクション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 Workday.
- 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 Workday.

Create VCL Applications with Connectivity to Workday データ
Follow the procedure below to start querying Workday 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 Workday.
- 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 Worker_Reference_WID, Legal_Name_Last_Name FROM Workers WHERE Legal_Name_Last_Name = 'Morgan'
- 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 Workday with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to Workday のデータ. This section provides workdayspecific examples of executing queries with the TFQuery component.
Connect to Workday 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 Workday ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to Workday 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 Workers where legal_name_last_name = :Legal_Name_Last_Name";
FDQuery1->ParamByName("legal_name_last_name")->AsString = "Morgan";
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 Workers where legal_name_last_name = :Legal_Name_Last_Name";
FDQuery1.ParamByName("legal_name_last_name")->AsString = "Morgan";
FDQuery1->Open();
