AND, OR, and NOT, Part 2 of 3

Posted by admin in D. WHERE Clause

> NOT does not connect two conditions like AND and OR.
Instead it reverses a single condition.

> NOT is placed before the column name or expression
and not before the operator.

> NOT acts on only one condition.
To reverse two or more conditions,
repeat the NOT for each condition.

> The following two statements are equivalent.
Choose whichever style works best for you.
