Create a Profile for the ODBC Driver for Open Exchange Rates

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Open Exchange Rates. In the Database Painter, you can use wizards and the UI to work with Open Exchange Rates data.

  1. If you have not already done so, create an ODBC DSN for Open Exchange Rates. The DSN contains the connection properties required to connect to Open Exchange Rates data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • AppId

    Open Exchange Rates API は、App Id によるBasic 認証をサポートしています。 登録すると、App Id がアカウントダッシュボードに表示されます。 これをAppId 接続プロパティに設定してください。

    See the help documentation for a guide to creating a Open Exchange Rates DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the Open Exchange Rates DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Open Exchange Rates Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Open Exchange Rates data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Open Exchange Rates Source'" CONNECT USING SQLCA; dw_projects.SetTransObject(SQLCA); dw_projects.Retrieve();
