Arbitrary rule
An arbitrary rule uses SQL relational and logical operators. Unlike
range rules, arbitrary rules allow you to use any relational operator
and any logical operator to define the rule. In addition, you can
reference any number of table columns in the rule. Arbitrary rules
typically include the use of the OR logical operator to group data,
as the following example shows:
FRAGMENT BY EXPRESSION
zip_num = 95228 OR zip_num = 95443 IN dbsp2,
zip_num = 91120 OR zip_num = 92310 IN dbsp4,
REMAINDER IN dbsp5
