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
