Excel ODBC Driver

The Excel ODBC Driver is a powerful tool that allows you to connect with live Excel file data, directly from any applications that support ODBC connectivity.

Access Excel Spreadsheet data like you would a database - read, write, and update data through a standard ODBC Driver interface.



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

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

Connect to Excel as an ODBC Data Source

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.

The ExcelFile, under the Authentication section, must be set to a valid Excel File.

Create a Profile for the ODBC Driver for Excel

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

  1. In PowerBuilder, click Tools -> Database Painter.
  2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  3. On the Connection tab, enter a name for the profile and select the Excel DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

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