How to build a simple VCL Application to view Veeva データ in RAD Studio using the CData ODBC Driver for Veeva.
最終更新日:2023-06-12Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Veeva, you gain access to live Veeva データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve Veeva データ. This article will walk through connecting to Veeva and creating a simple VCL application with the Form Designer.
Create a Connection to Veeva 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.

Veeva Vault への認証
本製品は、次の認証メソッドをサポートしています。
- Veeva Vault ユーザー資格情報
- Azure AD 認証プロバイダーのOpenID Connect
- Okta SSO
ユーザー資格情報
AuthScheme をBasic に設定し、User とPassword をユーザーログイン資格情報に設定します。
その他の認証方法で認証する場合は、ヘルプドキュメントの「接続の確立」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 Veeva データ.
- 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 Veeva.

Create VCL Applications with Connectivity to Veeva データ
Follow the procedure below to start executing queries to Veeva 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 Veeva データ.
- 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 ProductId, ProductName FROM NorthwindProducts WHERE CategoryId = 5
- 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.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
