Question intentional UPDATE exception

[Noremacam]

This question may not be specific to mysql. How do I make an UPDATE statement that will throw an exception if zero rows are affected by the update? Or is there an alternative that I'm missing?

Check if your dataset has any changes.

If yourDataSet.HasChanges() Then
    'Code to do your Update
Else
    MessageBox.Show("No changed records")
End If
