This example demonstrates the Execute method when run from both a Command object and a Connection object. It also uses the Requery method to retrieve current data in a recordset, and the Clear method to clear the contents of the Errors collection. The ExecuteCommand and PrintOutput procedures are required for this procedure to run.
Use the following example in an Active Server Page (ASP). To view this fully functional example, you must have the data source AdvWorks.mdb (installed with the SDK) located at C:\mssdk\samples\dataaccess\rds. This is a Microsoft Access database file.
Use Find to locate the file Adovbs.inc and place it in the directory you plan to use. Cut and paste the following code into Notepad or another text editor, and save it as Execute.asp. You can view the result in any client browser.
