BUG: DAO dbFailOnError causes RecordsAffected to return 0 (195226)

MORE INFORMATION

When you run an action query, you can find out how many records were affected by examining the RecordsAffected property of the Database or QueryDef object. If you specify the dbFailOnError argument so that you can trap for errors, the Microsoft Jet database engine incorrectly returns 0 for the RecordsAffected property.

Steps to Reproduce Problem

1. In Microsoft Access or Microsoft Visual Basic, create a new project with a form (Form1) and a command button (Command1).
2. Add the following code to the form's module:

         Private Sub Command1_Click()
         Dim db As Database
           Set db = DBEngine(0).OpenDatabase("", False, False, _
         "ODBC;driver={SQL Server};server=xxx;uid=;pwd=;database=pubs")
           db.Execute "Update authors set city = 'Paris' " _
            & "where city = 'Oakland';", dbFailOnError
           Debug.Print "To Paris:", db.RecordsAffected
           db.Execute "Update authors set city = 'Oakland' " _
            & "where city = 'Paris';"
           Debug.Print "To Oakland:", db.RecordsAffected
           db.Close
         End Sub
   
      NOTE: You must change the connect string in the OpenDatabase method to
      point to a valid data source.
   					

3. Use the Projects|References menu (or Tools|References menu) to add a reference to the following object library:

   Microsoft DAO 3.5 Object Library
   
   -or-
   
   Microsoft DAO 3.51 Object Library

   NOTE: Microsoft Access has this reference by default.
4. Run the project, open the form, and click the command button. The Immediate/Debug window will display 0 (incorrect value) for the first result and the correct number for the second result.
