I have some data that is being enter into the system and sometimes the user will hit an extra key. I need to know how to averge this data so that I will know that the user hit an extra key.
For instance the user normally average anywhere from 20 to 25 snacks a day. So when entering in this data 123 is entered which is an error. I want to flag the error . I am a beginner with Sql so if you could explain I will appreciate.
