The following logical operators can be used when defining conditions, for instance at decision points or in boolean expressions:

- like
- <
- <=
- >
- >=
- =
- <>
- !=

<> and != can be used equivalently.

In order to negate a boolean value or expression, use the boolean not() function, for instance not(a and b). Refer also to not of Boolean Expressions. |
