Connect to Access Data from PowerBuilder





Access ODBC Driver

Microsoft Access ODBC ドライバーは、ODBC 接続をサポートする任意のアプリケーションからリアルタイムAccess データに連携できるパワフルなツールです。標準のODBC ドライバーインタフェースを使用して、どこからでもAccess データベースに接続できます。

This article demonstrates how to use the CData ODBC Driver for Access to connect to Access data and execute queries in PowerBuilder.

The CData ODBC Driver for Access can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to connect to Access data and execute queries from the Database Painter and controls such as the DataWindow.


Create a Profile for the ODBC Driver for Access

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

  1. If you have not already done so, create an ODBC DSN for Access. The DSN contains the connection properties required to connect to Access 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:
    • DataSource

    接続には、Access データベースのパスをDataSource プロパティに設定します。 See the help documentation for a guide to creating a Access 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 Access DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Access 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 Access data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Access Source'" CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
