Logical Operators

Logical operators (and, or, not) enable you to logically combine multiple expressions to evaluate a larger, more complex expression whose output is true or false.

(left-hand side) (operator) (right-hand side)

These evaluations result in a Boolean output. The following operators are supported:

and

&&

((1 == 1) && (2 == 2))

true

((1 == 1) && (2 == 3))

false

or

||

((1 == 1) || (2 == 2))

true

Exclusive or (xor) is not supported.

((1 == 2) || (2 == 3))

false

not

!

!(1 == 1)

false

!(1 == 2)

true

The above examples apply to integer values only. Below, you can review how the comparison operators apply to different data types.

Usage

Logical operators are used to perform evaluations of expressions covering a variety of data types. Typically, they are applied in evaluations of values or rows.

Example data:

X

Y

true

true
