Performs a logical negation on a numeric expression.
NOT Expression1
Expression1
A valid Multidimensional Expressions (MDX) expression that returns a numeric value.
A Boolean value that returns false if the argument evaluates to true; otherwise, true.
The NOT operator treats the expression as a Boolean value (zero, 0, as false; otherwise, true) before the operator performs the logical negation. The following table illustrates how the NOT operator performs the logical negation.
| Expression1 | Return Value |
|---|---|
| true | false |
| false | true |
