Connect to xBase Data from PowerBuilder





xBase ODBC Driver

xBase ODBC Driver は、ODBC 接続をサポートするさまざまなアプリケーションからxBase 互換データベースへの接続を実現するパワフルなツールです。

FoxPro およびClipper のようなxBase データベースに標準ODBC 接続でデータ連携。

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

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


Create a Profile for the ODBC Driver for xBase

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

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

    DataSource プロパティを.dbf ファイルを含むフォルダの名前に設定してください。 .dbf 以外の拡張子を持つxBase テーブルのファイルで動作するようにするには、IncludeFiles プロパティを指定してください。 複数の拡張子をカンマ区切りリストで指定します。

    See the help documentation for a guide to creating a xBase 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 xBase DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

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