Chapter 8 Using Expressions and Operators : Logical Operators

Logical Operators
Logical operators join or negate expressions in rules language statements.
Valid Operators
The following table lists the logical operators that you can use with the rules language (both the word and the symbol are valid). The logical operator OR (|) takes precedence over the logical operator AND (&).
The expression evaluates to true (Y) if either logical operand is true, or if both are true.
The only permissible syntax for use with LIKE is: WHERE NOT(fieldname LIKE 'value').
Notes on the NOT Symbol
In ostty, you can enter the NOT operator by typing the word “not”, or by typing a caret symbol (^) (Shift+6 on some keyboards).
