Combined condition Two or more conditions can be logically connected to form a combined condition. Syntax condition-1 {AND} condition-2 {OR } The condition to be combined can be any of the following: • A simple-condition • A negated simple-condition • A combined condition • A negated combined condition (that is, the NOT logical operator followed by a combined condition enclosed in parentheses) When relation-conditions are written consecutively, any relation-condition after the first can be abbreviated in one of two ways: • Omission of the subject • Omission of the subject and relational operator
