Data that did not match any records

There are several ways that can be used in order to filter the data that you do not want your SQL statement to work on. The use of the keyword "not" can be used in any condition. With the presence of that word, the condition will be negated and consequently data that would otherwise not be ignored will be ignored.

 

Having said all that, here is a link to a basic tutorial:

Hope it helps.
